I lost a common goldfish to high nitrates a year ago. Since then I've
been trying to get the nitrates under control (unsuccessfully). I have 2
goldfish, a 5 inch common and a 3 inch fantail and they were in a 10
gallon tank. They both just sat around on the bottom of the tank most of
the time and the common goldfish has weird lumps on his sides. No amount
of water changes would bring the nitrates down so this week I bought a
30 gallon tank for them.

I can't speak to the environment, but perhaps they are bored. Goldfish
like to shoal together and root for food on the bottom. Maybe they have
nothing to do? What do you have in the tank?


I thought would help and that they would perk
up but they still sit around on the bottom. There is a little ammonia in
the water right now (about .25-.5) but all of the other parameters are
great. Are these little guys just permanently brain damaged from sitting
in nitrates for a year?

Is it Nitrates or Nitrites?
