Poor water quality, keep up with the water changes, and increase aeration in the tank, how many gallons or litres in the tank, and how many fish are in the tank.
And how long has the tank been set up.

Swim bladder can be fetched on due to poor water quality and diet.
Are the fish huddling together.

Last night everything was fine, and this morning I wake up to 3 dead pim pictus (all I had) and 1 dead p. demasoni, and I'm not sure why.

Tank stats: 75gal, fluval 404, AC 70, temp: 79 F, Ammonia: 0, NitrIte: 0.5 (I think this is from 4 dead fish overnight, because 3 days ago nitrite was 0), Nitrate: 5. Did my 50% weekly water change yesterday as per usual, I used dechlorinator as I always do.

This tank was fishless cycled and on 6/20/06 I added 7 L. Caeruleus, 6 P. Acei, 6 M. Callainos, 1 P. demasoni, all juvies w/the exception of 3 adult labs. A week ago, I added 3 pim pictus, all around the 4 inch range. No ammonia or nitrite spikes of any kind until today, or some time in the last 3 days since I tested. All the fish were eating well, including the pictus, except for 2 holding labs, and the demasoni. I thought she (demasoni) was holding, though it was hard to tell because she was so small, anyways she hadn't eaten since 6/30. Now I'm beginning to wonder if something wasn't wrong w/her from the start.

Answered your other thread it sounds like an internal bacteria infection.
