I have about 30 African peacock cichlids in a 20 gallon tank there are a few months old everything seems to be normal except one fish has really ballooned up in the last couple days. Is there anything I can do to fix this problem ?
29 healthy Peacock Fry out of 30 isn't bad. You might transfer the bloated baby to a hospital tank and fast him for a few days. That might allow his system to eliminate the blockage.
Don't fast the healthy fry.
