I have 2x 2.5g nano tank, all my fishes just died because of the broken power head. Now the tank is full of some kind of "micro worms". They are white colored, snail like, and they are mostly attached to the glass/acrylic. There is a bunch of these things climbing now. Are these good or bad? Should do a water change or complete kill the tank?

if you have no fish, just re-start everything

You mentioned fishes... how many were there in that 2.5g tank?... please do not tell me it was more than two.....

Those white things are called parasites. Typically all fresh water tanks have parasites hidden in the gravel. I would usually use the python to suck out the parasites and the poop on the bottom of the tank.

That's not necessarily true. There are a lot of "good" micro critters that can and do live in freshwater tanks. I can't say with 100% certainty without seeing them, but hey are most likely some sort of planaria or freshwater limpet, especially if the tank is newly fishless. Many fish eat them and this usually keeps the population in check. In fact planaria in particular are thought to be key to the captive survival of some sand sifting fish like Mooseface loaches. It's only when there is a population boom (either through lack of predation and/or over feeding of the tank) that you'll see them on the glass or in the water column.

I agree and think they probably are planaria, most likely from overfeeding as a tank that small difficult at best to judge of how much to feed.

I'm also curious as to what fish you had in there?
Also not sure why you would have had a powerhead on there..didn't you have a filter on the tank?

Best to drain & empty the tank, wash the gravel thoroughly with tap water (will kill anything living in it). Then rinse the tank with water & bleach (9 parts water to 1 part bleach), drain, rinse well & let it air dry.

Then start over and cycle the tank again before you add new fish.

yeah just give the tank a good scrub down i believe they are planaria too, give us some pics, i had them before from overfeeding my discus, but 2.5G is small.... even for freshwater, unless ur keeping shrimps or something

I'd bet they are Trumpet snails, Very hard to be rid of..All you need is 1 to have a tank full down the road. They are very hardy creatures, make sure you do a total breakdown,filters and anything else you have in that tank..

[nycfatcow]

You can try using really hot water to rinse down the tank and everything... that usually works...and as others had said it is probably from overfeeding
