  • what fish are in there with it?

  • I'm curious about how big ur tank is too :)

  • @Purality 240 liters

  • @sqbbe is that a ropefish i see close by or a dinosaur eel?

  • @ryanw00dddddddd ropefish

  • You have a very nice pair of kribensis :)

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

  • That looks alot like Bloodworms

  • If you continue to feed him beef heart...he will outgrow your tank very quickly ....it is like fish steroids!!!! I speak from experience

  • how big is your tank?

  • Won't he eat the smaller fish? I since they are predators and carnivorous I would be worried about them...

  • do you just throw in the frozen beef heart straight out of the freezer or do you need to defrost first?

  • @TebooTedMarshall you just throw them in straight from the freezer

  • @sqbbe you should defrost it, but i don't think it makes a difference.. it hasn't with me :D

  • @TebooTedMarshall About frozen beef heart it is best to defrost it atleast a little bt before feeding this makes it eazier for the fish to eat it the down side is it will be a little messy so many people throw it in frozen so it stay in one piece

  • Yes j1nxowner they will eat flake food at first. Once mines got large enough to eat feeders then he didnt touch the flake food

  • he must be the biggest black ghost i seen so far

  • That fish looks awesome and very healthy. Does it ever eat your little fishes?

  • I also have one in my tank and I feed him brime an blood worms. He loves them.

  • would a thirty gallon tank be big enough to house him the only thing in it is a dragon goby and it seems to have plenty of space(it looks more like a 40 gallon tank) i also have a cory dora but if hes eatin not to be mean but not a big deal

  • are they blind or just seeing verry bad?

  • Are these aggressive?

  • Killer Fish! I am thinking of getting one!

  • do black ghost knife fish kill smaller fish say 10cm

  • nope their friendly but agressive to their own kind

  • @neweditionmaterial Of course they do i, mean i had loads of new born guppies and 1s with fair growth all got eaten by the Bgkf

  • black ghost knife fish looks like dogs

  • he looks big?how big is he?how bigs your tank,does he bully the little ones?

  • black ghost knife and rosy barbs for the win!

  • mine eats worms, dead fish, shrimps, and ham

  • how much did you buy yours for and where?

  • i dont no about were he gt it but i got mine 4 $8

  • what is that its eating?and is that its daily diet?

  • He`s eating frozen beefheart. He gets that 2 3 times a week

  • i have one ghost fish and yes it eats flake food or dead fishes

  • lucky, mine wont eat flakes, just frozen brine shrimp

  • i used to have one do you think that a new one would be ok in a semi agressive tank

  • yes. I have 2 Alligator Gars, an Oscar, and a Black Ghost in a 120gallon setup.

  • would they eat flake food ?

  • not in my experience

  • @j1nxowner I've got 1 and mine has always eaten flake food.. after a few months i told my local fish shop that I've got 1 and he said I should give it bloodworm but then went on to say that if its been eating flake food for a few months and theres no problems then it can carry on with flakes... I've had it for over a year now..

    simple answer should of been yes but I thought I should go into detail

  • @j1nxowner some can, but they prefer life or frozen food at least. 

  • excellent mate really healthy fish tank mate bgk is out of this world

  • Oh my, what a beautiful BGK! We have a little one in our 125gal tank. Well, it's not little little, but still a youngin :) I can't wait for it to get big like that one though! They have the cutest faces :D

  • Hey i just bought a black ghost knife yesterday and wat should i feed it

  • frozen beefheart and/or frozen red bloodworms

  • frozen bloodworms i had one now i have an african brown ghost knife

  • how big is this tank?

  • 240 liters

  • That is the biggest, healthiest and most active Ghost knife I have ever seen, good fucking job dude,wow.

  • r u serious?wow that is real ive had one

  • i have three

    lol i was joking

  • love the plants. are they some kind of onion?

  • its a cool fish I have some bass at home

  • i went by a pet store 2 days ago to buy more fish and bgk totally caught my attention i got two, im amazed with them knives... very unique...

  • i like your tank, really cool variety its too bad you had to sell your knife. how long did it take him to get that big?

  • He grew that big in one year

  • sweet kribs--i got meself a proven spawning pair---their favorite thing is the lava rock (sandsifters, cave spawners) cool stuff really

  • Hey what kind of grass is that? Do you use fertilizers? Cool fish!

  • The plant is Vallisneria and I didn`t use fertilizer

  • Very gorgeous fish! Hope his new home is treating him well :)

  • wont he eat the other small fishes

  • He grew up with small tetras and I guess that`s the reason he doesn`t eat them. And the fact that he was fed very well.

  • How big is he today?

  • I sold him a 3 months ago when he was about 35cm

  • D= but why? are u a breeder? doesnt matter anyways its ur choice. wat kind of blood worms did u feed him? frozen or if there is even fresh? uhh mine tore through a tiny cubed frozen one but thats the first time i saw him eat for like half a week! my first half a week too and i was so glad i through the other half of the cube in, glad he didnt snack on my pleco or 2 angels on the way XD i am going to go through frozen pack before i try..not frozen...if its even any "better" or what ever he likes!

  • I sold him because he was way to big for a 240 liter tank.

    He only got frozen bloodworms, never tried the fresh stuff.

  • how big do they get.

  • They can grow up to 50cm

  • They can grow to 50cm

  • Those fish are nice and cute when they're small just like Plecos

  • and dogs, and cats, and cows, and humans.

  • very nice... gsk in las vegas dont live long for some reason lol

  • do u have autaras in that ?

  • Don't GK's need at least 75 gallons.

    I went to the pet store today and thats what the guy told me . .

    but I didn't know they could get 2 be 2 feet long . .I was told 1 foot . .and i have a 35 gallon tank . . so that was a bummer . .

  • hey jarkkofan you shouldnt worry about about your tank size. I have a 44 gal pentagon corner tank that i just started and i bought 3 of these guys. they dont grow fast so you really have nothing o worry about. my Cichlids will most likely outgrow em before they even grow an inch. go get one man =D

  • one other thing, anyone recommend a commercial food, cos mines will only eat frozen bloddwom, daph etc but it'd be handy to have something commercial

  • wow that BGK looks like a beast, what size is it? ive had mine 4 yrs and its only 6 inches long lol

  • Do you think those black ghost won't eat 1 month old guppies??? I had mine extinguished eventhough they were smart at hiding and running away from neons and rainbows...I felt so sad

  • BGKs are predators and they may eat neons and guppies. Mine didn`t eat the cardinals I had but I think I was lucky with mine speciment.

  • does your blackghost eats neon tetras??? it seems my 1 month old guppy kids has been eaten by my two 10cm blackghosts...there were 7 of them, only one who were growing bit faster than most were left unharmed.... I am so sad...it was my uncle who recommend me to buy those two ghosts...He told me that it won't eat those guppies but seems like they did....

    what do you experience with those little fishes or are some a bit more predatory???

  • Very nice knife! Mine has developed his own way to eat. I only feed him every other day due to his diet but he gets mad that other fish on flake food get feed every day. Now he swims upsidedown and backwards along the top and eats all the flakes! I am not underfeeding him he is just a pig! haha. Him and my two dojo loaches are my favorite fish to watch. They the most personality of any fish I have ever owned.

  • wow that is some crazy fish where did you get it?

  • hey..what kind of food do you feed him..is that cooked beef or raw?

  • I`m not sure if it`s cooked or not. I by it frozen from the store.

  • My BGK won't eat if light is turned on

  • I have a 650 liter AQ, and would say its the minimum size to keep this fish. I have 2 one about 15-20cm and other +30cm. Very teritorial and aggressive towards other likes, so you need a lot of hiding places for each fish... Eats about everything you feed it:) If he doesnt like it he wont eat it:P

  • Thanks for the reply, also I have a ghost knife, zebra loach, angel, ram and three rosy barbs in my spacious, planted 29gal. Do you reccomend me getting a couple of neon tetra or cardinal? If so, which one? Thanks again. (you should show an updated version of your tank :)

  • Many say that the BGK hunts tetras, but I haven`t seen this. I would prefere to have the cardinals. They are more beautiful and "everyone" has the neons.

  • There is no such thing as a spacious 29 gal. You'll need at least 100 gal within a year, as it'll be nearly a foot long by then.

  • totally agree. Your tank is already completely overstocked. The 29 gallon shouldn't have Angels, Ghost Knifes, or Rams. its too small

  • well as far as the GK . .

    our local store as 3, Six inch GK's....in a 29 Galleon tank . . with other fish too . .

    [I asked what size the tank was] . .

  • what size tank is that? I have a baby bgk right now but i need to get a bigger tank asap

  • This tank is 240 liters and it`s way to small for a fish of this size. It should be at least twice this size.

  • WOW! You GK is very healthy, is that his full size? Mine is about that size. What are the plants in the background? Really cool.

  • Thanks. He`s almost full size. That plant in the backgound is Vallisneria

  • what are you feeding them?

  • I feed him frozen beefheart

  • awesome fish how old is it ????? i just recently bought one and already it is becoming a fav i have it in a cichlid tank but no1 bothers it

  • In this video he`s about 1 year old

  • i love these fish, can anyone tell me how to get them to not eat any mollies guppys ect because i think ill get one thanks!!

  • yeah don6 get mollies or gupies

  • there's really no way to unless you get a baby one. if his mouth is big enough to fit one of your fish in, it'll most likely eat it.

  • i need some help im re doing m tank all fresh with new fish how does this sound all together black ghost knife platies mollies siamese fighter golden apple snail and a pleco

  • That sounds alright

  • Well in mine i have a blck ghost,fire eel,african butterfly,2 ropefishes,weather loach,red tail shark,a pleco,algua eater and 2 albinos cleaning ugly fishes...and they all get along real great

  • aww its so cute. im getting one of those in four days

  • whats he eating!! i have one and i feed him blood worms!

  • He`s eating frozen beefheart

  • You do realise that feeding mammal meat to fish is very bad for them? You'll shorten their lifespan.

    Much better to feed fish meat like Tilapia.

  • I have two of these guys (different tanks). One of them has a curly tail, and he's the thickest one I've ever seen! He tries to kill my snails though.

    You have quite the active tank! I'm suprised the little fish will go near the BKG.

  • Hey thanks, I found the perfect place to buy a BGK, theyre very active there. I got two last questions. First one, will a fire eel eat neons, mine are like half an inch long. And the second one, how big is your tank?

  • I don`t think a fire eel will eat neons. My tank is 240 liters, which is way to small for a big BGK, so I`m scouting for someone with a big tank to give him a new home.

  • how big is 240litres in inches

  • Great BGK, those fish are so cool. I have a quick question.

    Im getting a new 40 gallon tank this summer and I wanted to know if an Elephant nose, Ghost Knife, and a Fire eel will get along? I heard that the ghost knife and elephant nose are really friendly and get along great with each other and fish like platies, neons, etc.

  • Some say that you shouldn`t mix elephant nose with bgk, but I have seen many that do it with no problem. If you like these fish you should go for it.

  • My BGK hides allday in his pirate ship and will only come out when i turn of the tank light. will he ever become more friendly?

  • It helps if you feed him with the lights on. BGK are quite sensitive to light so if you have powerful lamps he might never come out.

  • wat do they eat?

  • i feed him beefheart

  • Most interesting fresh water fish save the fresh water sting ray , maybe. They are compatible too. You can also keep them with discus and angels.

  • How would a 79 gal not be good enough for a 12 inch fish? I can understand about not housing alot of them together but have you ever seen breeding tanks that house hundreds of them and they are just as healthy as if they were housed alone.

  • Beautiful fish! I just got a new 79 gallon tank 150x51x66 cm: will it be sufficient for a black ghost knife fish? :)

  • It will be to small when the black ghost is fully grown

  • hey a 75 wont be big enough theres a vid on here of one in the wild pretty sure its bigger than 12in just type in amazon black ghost knife fish

  • can i put 2 BGK together in a 200g tank??

  • Yeah I think that would be okay, because with such a large tank they`ll probably make their one teritory.

  • Like sgbbe said it should be okay , I had two in a 55 gal and there wasnt enough room to each esatblish territory, the smaller one eventually died probably had a hard time feeding because of the sonar.

  • could you mix a black knife, and a clown knife together?

  • I guess so if the ghost is at least as big as the clown???

  • Hey, you have a very nice tank, in all your videos of you knife it looks like hes getting bigger. how many of those could i put in a 38-gallon tank? and i was thinking 3?

  • They say you should never have more tha one BGK in a tank, because the electric signals they send out disturbe the others. A 38G tank is also way to small for a fish like this. They get very big and need the space. They sould at least be in a 130G tank.

  • Is thats those cubes of beefheart you are feeding him? or do you have a whole chunk of it, that u cut peices off of it?

    Also, how do you get yours to sink? I have the cubes of beefheart, and mine dont sink, they float.

  • I feed him with cubes of frozen beefheart. They just sink. I don`t need to do anything to get the to sink.

  • Hmm.. thats weird, because mine dont sink.

    Can you tell me what brand of beef heart you buy?

  • "Fina fisken"

  • were did you find that fish?

  • GOOD

  • How do you pre treat your water before doing water exchanges?

  • I don`t do anything to the water before I do the water exchange.

  • thats a ghost knife??? o_0

    wow i didnt expect it to be as big as that??

    i saw that fish in the shop about the sise of a small goldfish

    can it grow bigger than a clown knife?

    are there any more fish like them?

  • No they cant get as big as a clown knife, but they can get quite big. Max size 50cm.

  • he wont eat the little guys

  • cool ty man

  • he is a real beauty, can u hand feed him?

  • I have never tried it. I want to keep my hands put of the aquarium as much as possible.

  • i have a BGK too bur mines way shy he wont come out of this log any ideas on how to get him out

  • What do you feed him? If they get something they really like(like beefheart) they`ll usually come out.

  • They can be very mean to Other BGK! I have seen ppl fight them, almost like dog fighting. Sad but true. But watching them swim is the coolest!

  • do you have any tips on how to make my BGK not shy just got it yesterday...

  • when your bgkfish what did you feed it and how did you do itwhen did you usually feed it

  • Haha that kribensis had no say i it, the BGK was havin its food too!! lol great fish

  • your tank is awesome. It's on my favorite's. Do you think the following mix of fish will work/look nice? - 1 BGK, 1 reticulated stingray, large shoal of serpae tetras, a pair of red crayfish, 1 reed/rope fish, and possibly a pair of discus. With driftwood, plants, and white sand.

  • I`m glad you like it. It sounds like an interresting mix, but BGK and discus don`t mix well(have I heard).

  • thanks for your help. I 'll try getting a cheap discus and if it lives, I'll trade for a good looking, expensive one. btw, i'm not getting a reed fish, but a fire eel instead.

  • you got an eel in there?!

    i can see it at 0:35

  • Yeah. It`s a reed fish. I got 2 of them. They are about 36-37 cm.

  • knife fish dont eat small fish?

  • ok so it might be ok if i get a biggfer tank? I want a tank set up like yours that was the idea those would just be the main fish I was just worried that the white ips were just a bit to rambunctous for the needle fish and knife. but thanks for the help cool tank and nice vid

  • I started with eight baby black ghosts in a 75-gallon tank, with no other fish in the tank at all. It's been fifteen years now, and I have two left, one of which has grown to a pretty massive 16 inches in length. They're by and large peaceful, but I have seen them fighting each other and that can get pretty brutal as they jockey for territory in the tank.

  • hey is is ok to put a black ghost knife in a 50 gal. tank with 3 white tip sharks and a needle fish or will they kill each other?

  • I`m not sure. In my experience the black ghost is a peaceful fish, but each speciment can have different behavior. A 50 gal tank will eventually be to smal, because this fish grows big fast.

  • you have beautiful fish hey. i love my ghost knife's and i had one at almost 20 cms so to hear yours are so big and they're very healthy one question though...what are you feeding it? they love it! mine takes frozen blood worms from me so i was curious. ne ways great fish!

  • Thanks for the comment. He likes to eat frozen beefheart. He sometimes eat frozen red bloodworms aswell, but the favourite is the beefheart.

  • I'm sorry but eventually all of your neon tetras will be eaten by the ghost knife.

  • I don`t think so. He`s quite peaceful and gets plenty of food. My tetras are cardinal tetras. They get bigger than neons.

  • How long does it take for this fish to get up to this size?

  • Aprox 1 year

  • they can grow up to 50 cm
