I have this repeat problem: I stock a 70 gallon tank with sunfish I catch using minnow traps. After a couple of months the fish start showing excess slime production and die. I have a canister filter and a hang on the back filter on the tank. I feed them twice a day. They eat avidly. I checked the ammonia and nitrite today and it is fine.

There are about 4 dozen 2 inch dollar sunfish, bantam sunfish, red spotted sunfish, blue gill and a few oddballs in there.

I started treatment with formaldehyde today.

I would suspect crowding, but the NH4 and NO2 is fine. I do a 50%+ water change every month.

Any suggestions?

IS THIS A BAIT TANK?
your tank is over stocked for sure!
i would vac the gravel every week and do a 20% water change @ the same time.your fish are weak and they get ill.
add salt to your water.and look into building one of these for a tank this heavily stocked.

Not to start a fight, but this does not sound like advanced captive care. You are significantly over-stocked, and significantly over feeding. You probably dont want to hear about the over-stocked, but at least slow down on the feeding... fish could easily be healthy eating every other day (four times less than you are feeding)... and that has to have an effect on water quality whether you are measuring it or not.

I agree with all previous statements. Good thing this wasn't posted on a tropical fish-keeping forum, as you would get reamed for having a severely overstocked tank. But in all honesty, you do. You seriously have 48 2'' fish in a 70 gallon tank? Also, what is "fine" when you speak of your nitrite levels? Just to reiterate, decrease number of fish, change water more often, feed less. Ugh, I DO sound like a frustrated tropical fish-keeping forum member...

Edit: I hope this doesn't come off too harsh. After reading it back to myself, I know that tones can be misleading when we can only type to one another.

What are your Nitrate levels and as asked before what are your actual nitrite and ammonia levels? do you have much water surface agitation? Being that overstocked the fish would be pretty stressed. Also do you quarantine any of the newly caught fish before adding to the main tank?

First thing i would do is re-home at least 1/3 of the fish, just so the tank has a fighting chance of stabilizing. I know this is my first post on this forum, but I've been keeping fish for years. Good Luck...
