    "Black Ghosts are carnivores so I feed HER frozen food like bloodworms, artemia, krill and gammarus shrimp."

    i just got one today :)

  • It's almost impossible to distinguish male from female in this species, so I just randomly called it "her".

  • nah there pritty easy fish but they need to eat blood worms

  • i saw one at my petshop but was wonderin if i should get it i have a 15 gallon aquarium will dat be enough to make the knifefish happy and what does it eat and is it hard to take care of?

  • @xXxGildartxXx 15G isnt enough... it grows over 20inch long.. may b 150 gallon tank would do..

  • Are these similar to the African Brown Knife fish?

  • How much do they sell for where you guys at? 74.99 in hawaii

  • @Tinwelende only 14 bucks in canada

  • @Tinwelende i feel lucky being in malaysia... i bought about 4 for 2US dollars each... but didn't have luck with them, pretty hard to keep in a community tank... and very shy

  • @MrBballin32 $12.

  • @MrBballin32 17to 20 dollors

  • don't do oscars with them-- we thought our knifey's would be alright, but as soon as our big red oscar's mouth was big enough, he bit the head off of one of our BGKs :( I don't recommend learning this lesson the hard way like we did- oscars grow very fast and have a huuggee appetite

  • I want to get one so badly, do you think they can live in a 20 gallon fish tank?

  • Abaolutely not! They need at least a 140 gallon tank!

  • @Tinwelende

    Not true my friend.30-40 gallons is a decent minimum size, when buying them small (2-3")

  • Ever considered the fact that they will grow, though? In the beginning they're fine in a smaller tank, yes. But people buy them just because of that and doesn't take into consideration that they'll soon need to buy a bigger tank, which they can't afford. And if you can't, you shouldn't buy this fish at all.

  • @Tinwelende

    I have, but remember that fish do a great job of adapting to the size of their environments. Now obviously that doesn't mean a 75 gallon fish should be kept in a 10 gallon tank. However, I have two needlenose gars in my 55 gallon thank that are about 6" long, and about 4 years old. There are also needlenose gars in the lake at my university that are well over 3 feet long.

    I understand what you're saying though, I just think 40 gallons is acceptable.

  • They do because they get distressed in too small spaces, which causes negative stress to their bodies, and organisms under stress like this don't develop as much as happy organisms do, therefore the smaller size. They've done experiments like this on human children as well, measuring their height compared to their living conditions and how much stress they've been put under during their upbringing. So it's the neglect that causes them not to grow as big as they do in the wild.

  • @Tinwelende Go to PetsMart and check the tag!

  • i brought mine today..he seems to be settling nicely

  • What temp do I need to put my tank? I'm getting one and need to know.

  • Between 72 and 80 degrees F is what a black ghost prefers.

  • We are wondering whether to put some Oscars in with ours. Figured if maybe we start with small Oscars n they kinda grow up together they might be ok? Guess its the luck of the draw if they get on!

  • Yes, I think so, too. It's a risk, but small oscars SHOULD be ok. But, ya... you never know... :S

  • Comment removed

  • @makkapakka5 But Oscars grow so quickly, so you'll have to start with a larger, older ghost fish and then get the small, baby oscar

  • @makkapakka5 But Oscars grow so quickly, so you'll have to start with a larger, older ghost fish and then get the small, baby oscar

  • Can BGKs be kept with Blood parrots?

    I've gotta admit one of my 4's is pretty retarded..

  • Comment removed

  • I think the parrot fish might be too harsh on the BGK, so I wouldn't risk it.

  • @Tinwelende

    But i've seen people keep them with Oscars... :/

    I bet if i provide them multiple hiding spots they'll be ok..?

  • It's very individual, but my experience is that parrots are a bit more... bitchy, than oscars...

  • @Tinwelende

    Wow my 4 inch knife fish is still there...along with 4 yoyo's

    I guess its really about the hiding places..

  • Had one, he was my favorite fish.... He was huge and stayed in a log all the time, except when he ate... Mine hated the light, only came out when it was dark... He ate some type of fish chips I bought, came out and scarfed them up... Found him floating dead in the tank one day, don't know what happened - hoping it was just old age as the other fish have been fine...

  • help i need to find out waht they eat please help im desperate.

  • They are strictly carnivorous, so feed him only animalistic foods, like blood worms and brine shrimp and such things. Blood worms are good, cause the knife fish likes to scavenge them from the bottom.

  • @malia2010910 They need bloodworms.

  • Why does a tiny black fish ghost need a huge tank? i wanna get a black ghost & ima put him in a 10gallon tank just him why is this a bad idea?Please reply thanks.

  • Because he will grow up to 20 inches no matter what and require a 145 gallon tank eventually! You can keep him in a smaller tank for now, but you WILL NEED a much bigger one eventually. If you don't have that kind of a tank already, you should not get the fish, either, cause you never know if you'll be able to buy a tank like that in a year or so or not.

  • @Tinwelende i know that but im saying i mean a lil thing as 20 inchs in a 145 galon or 120galon tank is just i mean why tho?

  • The smaller it gets, the less he'll thrive. That's just how it is. I didn't come up with the 145 gallon, experts did. 120 gallons wouldn't kill it (right away), but he'll have a longer, happier life the bigger the tank is.

  • can u please tell me the name of the fish in 0:43 .. in the tunnel behind the  black ghost

  • It's a yo yo loach (Botia lohachata).

  • those look sooo kool! they look like feathers floating in the water, and the name is kool too!

  • Hi, my knife fish Hack has poop hanging from his "chin". Is that where it usually comes out or..? I'm new to knife fish, and I guess their anal fin leaves only the throat to poop from, but I'd like to be sure ;)

  • No, the poop comes out from their cloaca, which is located approximately after 4/5 of the body lenght. The poop on the chin has propably just come floating by and got stuck. It will probably go away by itself after a while.

  • @lucymia yes u r right in case of BGK there poop come out just after his chin end and where his fin started,, nothing to worry this is normal for him,but be care full dnt keep any sucker types of fish with black ghost knife.M faced problem before its sucked on the skin of BGK,as u know BGK dnt hv any scale so its bad for him and also can die for this reason so be careful.Also careful to add any types of chemical or salt adding in water ,bgk hv very sensitive skin which nay cause itching prob.

  • Can I feed him guppies and does it need a heater

  • Yes, it needs a heater. Don't feed it live food when you don't have to.

  • hiya! plz checkout my bgk video called black ghost knife-awesome fish

  • hiya! plz checkout my bgk video called black ghost knife-awesome fish

  • Nice BGK Come see mine on my page he is still just a baby: )

  • very nice aquarium. Can you please look at my black ghost knife fish? i don't think their growing cause im only feeding them bloodworms. can you please suggest other food for baby black ghost knife fish??

  • Brine shrimp, turkey heart, all kinds of animalistic frozen foods, since they're carnivores. I'd say that the more variation there is to their food the better it is and the more likely they'll grow. ;) And make sure they've got plenty of hiding places, so that they're not stressed. If they're stressed they won't eat as much and they won't grow. Good luck!

  • @thefishboy25 frozen beefheart is like a steroid for these guys - if you want your BGK to grow quickly, feed it to him/her 2-3 times a week

  • @notyetlaughing ok thanks!

  • @thefishboy25 they do take a while to grow as long as he's eating its fine they will look around for food scraps in the sand or gravel looks nice. iv found they like to hide facing upwards. they can get very big so dont wish him to grow to much lol

  • @thefishboy25 you have to feed iti with tablet feed that don't flows over the water.

  • what song is  this

  • Anam Cara by Enya

  • bought 1 yersterday.so excited. likes blood worm.

  • wow, fat loaches. nice!

  • Hey I got one but it's kinda swimming straight up like it's facing down .... What should I do ?? Anyone ??

  • What's The Max Size They'll Grow

  • Here you go: lmgtfy.com

  • the sucky things are called loaches right? i need some of hose in my community

  • Yes, they are.

  • is this fish tetra friendly? or agressive?

  • It's mostly friendly, but will grow really, really big and will eat anything that fits into it's mouth.

  • well, i got a columbian catfish, 2 silver dollers and pleco . im looking into adding a BGK to the tank and maby some other little interesting fish, maby an angel fish, or w/e ... my main consern is ... with the black ghost knife fish be agressive and attack or fight?

  • It's more likely that the angel fish and the other fish like that will attack the black ghost, but as long as you have a lot of hiding places, it should be fine. It's mainly nocturnal. But the black ghost needs at leasf 145 gallons to thrive, so if you don't have a big enough tank, I wouldn't recommend you to get one.

  • Whhere did you get the gravel?

  • Normal pet store, but in Sweden. 

  • I just bought one today (July 21st). It was on sale at Pet Smart. I put it in my tank and it immediately hid under a treasure chest ornament. Are they hard to care for? I bought a packet of frozen blood worms. Should i put the cube in frozen? I just wan to be sure it gets food.

  • Yes, they are quite sensitive to water conditions and such. They are nocturnal, so it will hide most of the day. Try to feed it once you've turned the lights off at night. You can put the blood worms in frozen. Hopefully it will be easier for it to find them that way. Your other fish will try to eat them, too, so try to put it close to where the bgk is hiding. It might take weeks for him to dare to get out of his cave to eat, though. Good luck!

  • @Tinwelende Thanks for the info. It is still hiding right now. I put the blood worms under the ornament where it is hiding! You're right! I think it will be a while before it ventures out into the tank! Take care!!

  • Can the black ghost knifefish shock you

  • No, it can't.

  • Wow, a beautiful BGK! I've had mine for about 3 months, about 5 inches :( how long did you have yours until it got that big?

  • He didn't get much longer than this before he died, actually.

  • Could i get one to put with my oscar, convicts, parrotfish, goldfish, and other cichlids?

    And plus im getting a fire eel, a gar, a pleco,puffer,and arowana.

    Would that be a good mix?

  • No, it wouldn't. For sure the arowana would eat it, and some of the others are pretty aggressive, too. Cichlids are also very tough, so a Black Ghost would not be a good alternative.

  • i remember mine called wiggly put he died ;(

  • lol @ the music

  • Mine is being eaten by my cichlids. His tail is now just a white dot. I think my poor fishy is about to die.

  • hehe, I have two pakistanian botias to, and waiting for the new aquarium for my black ghost. but he is a lot smaller, and the botias are around 12cm long, so they wont get in his tub until he is bigger =) Nice video by the way, I will upload one as soon as it is all set up =)

  • My lfs sells them for 12 bucks at like 3 inches or so I cant wait to get one

  • finally some one who understands bgks dont mindlessley kill neons/cardinals

  • i bught one today he is like 4-5cm long but he don´t eat but that maby cuz is only the first day

  • Yes, he'll start eating in a few days when he's starting to feel more at home in the tank. ;)

  • @Porre1337 I would try frozen bloodworms. Then as gets eating good try other varieties of food. I once owned an 18inch clown knife fish that wouldn't even touch feeders. All he wanted was pellets, krill, and bloodworms.

  • У меня такая же. Аптеронотус-обожаюю!!

  • BGK go for £10 at my LFS 2-3" hth

  • I have yo-yo and a BGK too,they get on fine,but my ghost is quite shy-he pops out but then reverses back behind cover :(

    I have an established tank and he is not new,i figure it's just him!

  • cost* sorry

  • can you get these guys at any pet store chain or do you have to go to more of an exotic pet store?

    and how much do these guys gost anyways?

  • You can get them at a pet store. I don't know what they cost in the U.S., but in Sweden they cost around 21 bucks, but it depends on the size. $21 is for a 3-4 inch one.

  • @Tinwelende a Bgk in the US is about $20

  • 5/5

  • Thanks for this I have those fish first I bought 2 but one died from getting attaked and after that 2 more died and now I know whom don it

    But there so cute and u know it!!!!

  • if it died the botia killed it i put a goldfish in with 2 botias and about 1 day later the botia attacked it

  • nice botia lochata and pllz dont get black ghost and lochata together the lochata will start atking the ghost

  • I would love to add a BGK to my aquarium, great video!

  • Could a BGK live with 4 African cichlids 1pictus cat 1 red tail shark 1 red belly pacu 3 tiger barbs.

  • All those fish can be quite vicious sometimes. They are all tough fish and BGKs are quite slow and clueless. Though it has no long fins that would attract the other fish except it's tail fin, which is very sensitive. All fish are different individuals, and I would guess that in your case, it's a 50/50 chance he'd be unharmed.

  • @Tinwelende BGKs are related to the electric eel which mean any tail nipping fish that would want to try to bit it would get a little shock and then probaly leave it alone

    and to be on the safe side i would get a bigger BGK unless all the other fiss are still babies

  • put it this way it would get attacked by the tigers, and the shark will attack it until its dead, thats what happened to mine

  • Nice, looking BGK! I have one myself. Very graceful fish (IMHO). :-)

  • whats this song???

  • Read the info...

  • Have you ever had a problem with your Ghost knife eating your Tetras or any other small fish that will fit into its mouth

  • I have not, no, cause my BGK never got that big before he died. I don't know why he died, but I've heard they are quite sensitive fish and tricky to keep alive. I know that they do eat small fish once they fit into their mouths, though.

  • nice vid of ur bgk 5 stars for the info on the side bar! my bgk is 5 years old and about 12inches long check my vid...keep up the good work!

  • no prob bro

  • i was talking to the abhipattu dude but you seem very informed uh Tinwelende

  • Oh, ok, I thought you were talking to me, since you commented on my video and not responded to his post.

  • BGK grow Huge bro and if you plan on putting it with the oscars i woudnt do it they can both become very aggresive and i think the BGK can produce a little bit of electricity

  • I've never had any oscars in my tank, I know they can become aggressive. The electrical organ is not strong enough to harm other fish, they use it only to locate insect larvae.

  • Hi I hv two tanks. One with tiger barbs and some chiclets and other with oscars and red devils. Can I add a BGK to any of these tanks? tank sizes are 70 gallon and 40 gallon.

  • I would say you need at least a 130 gallon tank to keep a BGK in good conditions, since it can grow so big, so I wouldn't recommend you to get one at all for any of your tanks, unfortunately. :(

  • yeh!^^ nice BGK i got mine for about a moth now

    on the day i bot him he got bite on his tail but hes doing fine now!^^ please rate mine^^

  • Nice looking bgk.....Check out mine he looks the same as yours..

  • How big of a tank does it have to be? I have a 20 gallon. Too small? I want one! Saltwater or Freshwater?

  • It's freshwater, but I'd say that it would need at least a 145 gallon tank to thrive... I didn't know that when I bought mine...

  • how do you keep your gravel in its colour?

    mine starting to have some blown colour thingy on my gravel...

  • It should stay in it's color (unless you have algae on it). Otherwise it's not a very good gravel, and the risk is that it gives off some kind of substance to the water if it changes color like that.

  • can someone help me can you put BGK with afrian cichids dont worry about water just will they get along

  • what song id that?

  • Enya - "Anam Cara"

  • I had one that lived for ten years, it was a small one and couldn't have been more than seven inches.

  • i don't have that fish O.O i have clown knifefish but that fish died on 7/09/2009 lol it died to day R.I.P Clown Knifefish

  • Thanks

  • The orange freshwater one,but mines yellow.

  • Ok, then I actually think they might get along. Nothing's certain, though, since all fish have their own personalities, but I think it might work. If you keep the tank temperature around 80 F and put a lot of plants in for the knife fish to hide in during the day, it should be all right. And you should have at least an 80 gallon tank for them, since both species grow really big. Good luck! :)

  • I've got one ,and does it get along with a parrotfish??

  • Do you mean the orange freshwater parrotfish, or do you mean the saltwater one?

  • i have a BGK along with my 2 tiger oscars and silver arowana and 3 red ear slider turtle and they get along fine my BGK is super cool with my tiger oscar but my african cichlids bites my BGK which i removed after i made the video..check it out!!!!!!!!!!!BGK!!!!!!!ty

  • Dude, word, no way. Oh ya but you do know that Oscars are also Cichlids. What ever, my Fire Mouth Cichlid is a bitch to my BGK but luckily I am Getting a 125gallon tank in a few days(other wise I would not have the BGK). It will be sweet. They will be able to have there own territories with out any trouble. There will also be a Fire Eel and my Alligator Gar. I will put a video of it on youtube once it is all done.

  • kinda graphic but you really know your stuff!

  • mine eats tonnes of food!

    when i got it 2 months ago, it was about 3-4 cm, now its like 10-12cm!

  • i have a blackghost knife fish :) they are shy lil fish and they tend to hide

  • I just got a ghost knife about a week ago and since then it hasn't come out of hiding once. I can see his head/tail occasionally under the fake coral or in the castle, but other than that not a glimpse.  My tank is a little overcrowded right now, and I'm saving money for another. Could that be why? Do you think he's stressed?

    Also, when he gets bigger do you think he may try to eat my Glass Cats?

  • He will probably not eat your glass cat fish. Not until he's fully grown in that case, but I really doubt it.

    Knife fish are really shy, but part of that is because they're nocturnal. But try to give him plenty of hiding places and then just wait until night time. ;) They're aggressive towards its own kind, so I'm guessing that because of this, they don't really have the need of swimming in a school and rather hide in daylight - which is safer, when being alone. Good luck! :)

  • mine died at 50 cm

    the thermometer exploded :( :'(

  • haha

  • :P NOT FUNNY :( ;P

  • 50cm? :O

  • yup :P

  • do you stay have it if so what can you put with it

  • No, I don't still have it, unfortunately. You can put all calm, friendly fish with it, that are big enough not to get eaten once the knife fish grows. Also you need to make sure the fish have the same water quality needs and the same temperature needs and such.

  • hey guys im an experienced hobbysist, and the bgkf is definintly one of my favs, one do not keep them with aggressive fishes thieir white striped tails are ideal for fin nipping,two good filterd well oxygenated water hiding places and some vegetation in your aquarium would be optimol, not to mention feeding them natural foods like frozen blood worms, some insects, they may be tricky to feed at first and may die so it is in your best intrest to buy a pack of bloodworms or brinshrimp good luck!
