I recently tried to keep peacock bass which later devoloped an infection and died. About two weeks ago I saw a school of babies(1.5") for sale and I bought three more. They ate well on blood worms, brine shrimp and on day two started eating pellets. They are being grown out in a 10 gallon at 82 F with hopes to move them to the 55 when they grow just a little bit more. The runt of the litter ate, but never trusted me(skiddish) and ate considerably less than his two brothers. four days ago he simply died, no symptoms of anything except his decreasing body mass. The other two continued to eat well. Today I woke up to find another one died that looked completely healthy last night. I still have one fat baby left that appears healthy. Is water quality to blame and i should continue to do massive water changes? are baby peacocks just really sensitive? Or does anyone have little tips or hints for ideal water quality/raising peacocks, my water is also pretty hard.
