Hi,
I recently bought 4 frontosas--3m and 1f--from a guy off craigslist. He had raised them since they were small. The males are each around 12" and the female is about 8". After bringing them home, the female began to show signs of float or air trapped inside of her. She is now swimming strictly at the top of the tank with her dorsal fin exposed. The problem is that her stomach is now sunken (looked normal when I got her). There is no huge pocket of air bulging out of her. I treated the tank with salt and have been doing a 30% water change every other day. The water parameters are pH of 7.8, ammonia and nitrite 0, nitrate 30-40ppm. She is eating (had a piece of shrimp a few hours ago) and is sectioned off from the group. The tank is a 100g and is a quarantine tank. They will be going into a 350g in a week or so.
What should I do to fix this problem?
