  • these things have invaded my 150 gallon aquarium. i put in a harsh chemical in my tan and hadt seen one sence.

  • These are good. No need to dump your tank. They are actually part of your cleanup crew and help to complete your ecosystem.

  • why the heck would u put a oscar in a 10 gallon!??!do u know how big they can grow ._.

  • those are flat worms (paramicieum) sp?

    it happens from over feeding your fish

  • hey its time to clean!

  • those are daphnia, also known as water fleas, they are harmless and usually occur due to overfeeding

  • If U Guys Had Brains There Called Dolphina or water flees

  • i have an idea, get yourself some mollies of platties, let em breed, and in a short time, all those lil things will be in the bellies of the fry

  • your fish shld eat those dude

  • it looks like an ostracod I just discovered in my tank, and I noticed tiny dots which moved too. probably came in on my plants (along with pond snails). they are kinda ugly, i hope i don't get an infestation like yours, even if they are beneficial, they creep me out.

  • dood, those thing are cleaning larva!XD the clean your aquarium. in my aquarium those things appeared and i saw my aquarium was cleaner.

  • looks like freshwater copepods they make wonderful live food

  • looks like mosquito larva. Have a filter?

  • They actually look like water fleas or daphnia which you can get from fresh water ponds or culture them at home. I used to hatch some daphnia for my guppy fry to eat.

  • fry

  • yay sea monkeys

  • i think i have those too!!!!

  • i have those too!!! they just came from no where in my turtle tank that ive had for like a year now.. didnt notice them til i put warmer water in it and got a new heating lamp...they are kind of cool to watch but would like to know what they are for sure

  • put pennys in your filter ,,, copper sulfate gets rid of all inverts

  • @lesterclaypool1 Good call, unless he has resident inverts he'd rather keep. I maintain a colony of shrimp and blackworms in every tank I have, and see them as vital indicator organisms, a source of live food, and a clean up crew. I don't have these big bouncy guys, but I do have some copepods that recently appeared along with planarians.... but they stay in one corner of the tank. I'm fine with that.

  • I have only one oscar now because he killed everything else in the tank. But I have the same problem.

  • So did you ever find out how to get rid of these pesky little things?? Cause turns out I have the exact same thing... sick! I have been cleaning the tank alot and they kinda die down for a bit... but then BAM there they are again and ten fold too! guhhhhhhhh

  • i wonder how they get into your tank in the first place, it's not like they can fly (which they don't)

  • the eggs can be dried so they can come in on fish food , plants , other fish ,, but usually plants

  • Try feeding your fish a little less and do more waterchanges, they sould dissappear then.

    As long as your fish and plants are healthy most bugs aren't parasites and can't do any harm. Bugs just appear when the water is too dirty.

    If you have small (semi) predatory fish like livebreeders, labyrinthfish, barbs, danios and tetras, they'll eat the bugs whan they get hungry. Most catfish will leave them alone though.

  • If you and get mosquito fish, Gambusia, they will eat their weight in ostracodes in no time. I use them to get rid of millions of them in water lily ponds.

  • These are ostracodes and probably came in with new plants or pond gravel. The eggs can dry out and survive. A hungrier fish will eat them but they are harmless.

  • Dude, those are mosquitos larvs, dont' you have a filter or somethig to have the water on constantly move? The mosqitos lay their eggs on static water.

  • I know what mosquito larva look like. These are not mosquito larva.

  • @wacvet there's a strange "crustacean" in my tank to, is like 4mm long, look liked to a shrimp, with 3 tails, white, don't know if it is a parasite or something, i tried to catch it but it went below the gravel, there are 2 Oscars and a Bubblegum Parrot, any idea about it!?

  • Sorry. I don't know what that would be.

  • @pablo2cabrera amiphipods they are good

    

  • @pablo2cabrera do u have a filter or airator it is a a type of shrimp that grow in still water

  • check out water fleas or fish lice i cant get a close enough look but copper sulfate get rid of all unvertabrites ,,, so put a few  green pennys in your filter it usually gets rid of them ,,, also sold under the name had a snail

  • On second thought i was wrong but they are bug but then they turn into spiders,mosquitoes and flys

  • spiders don't have larva...

  • i think(my opinion) those are babies i thing cause when i had one i saw those too in a couple months i saw them getting bigger i think you think they are bugs because its very dirty

    (MY OPINION)

  • arghh...I just noticed some in one of my aquariums. Did you get rid of yours and how?

  • the funny thing is before i watched this i thought they were baby fish

  • wow to think that i would actually watch this!!!!!!!!

    man i need a life.....

  • haha

  • put some larve eating fish in their like guppies or mosquito fish (that the right name?) or hell just put an oscar.

  • an oscar in a 10 gallon?

  • Those are ostracods, not copepods, and they are not parasites. Almost impossible to get rid of, though.

  • my mollies had around 100 babies and i put all the babies alone in the one of my aquariums that had an outbreak of these and they were completely gone within a couple weeks

  • i know what those are there a type of parasite( spelling?) the come around when gravel is old or really dirty there harmles the eat the dirt particals..my boyfriend hand them in his prannah tank them..buth they passed away..i don't know to tell you how to get rid of them.. but i know that i would sugest that if you ever get a new aquarm don't use the old gravel because that is what happend to let him get them

  • Not a parasite, a parasite would be something that lives in or on another animal to suck their blood/tissues etc. :) (Parasites wouldn't be harmless)

  • Comment removed

  • those are a tipe of freshwater shrimp probobly. Most likely they came through the water but their harmless.They only eat bits og things they find at the bottoms of rivers

  • Cyclops ! Form of copepod

    Usually harmless, and fish will tend to eat them if they are visible :)

  • they look like harmless copeds I wish my fish hadnt eaten them all mine came with the plants I got from area lake. the plants were added first to cycle the tank than added mollies who finished off every coped. Your lucky fish love to eat them and they are harmless

  • they are likely copepods, almost certainly some kind of crustation. if you can get a good look under 5X you could be sure. i doubt they will do anything but provide live food for the fish.

  • They look like moquitoes lavars.

  • omg i have little brown bugs like pepper size in ym tank also...but all i have are small algae fish...2 small n one kind of medium.all i did was give em goldfishy food.they eat that...but havent cleaned the water in a few weeks...could it be killing them?im scared

  • man if that ever happened i will just put the fishes in a nother bowl and dumb that thing in the pond i have a phobia of insects and that creeped me out

  • I did that the first time I had them. Then I realized what they were and that they provide live food for my fish, so I decided to let them be.

  • whoa, and the fish havent eaten them yet?

  • Actually, yes, the fish eat them. I'm now trying to figure out how they got there so I can get more and the fish will have more fresh food!

  • i have no idea what it could be, but if you do find out, send me a message so i could try it on my fish. lol

  • It may have come from freeze dried "tubifex worms" by Wardley.

  • once you put fish in there the rotifers are history.

    you would have to set up a tank just for breeding this crustaceans
