I have a large tank 180 gallon with adult tilapia fish. I rescued babies and was wondering how big should the younger fish have to be before they get ate by the adults? or do they have to be adults before I reintroduce them back into the main tank?
How long do adult tilapia fish live? when should I harvest them before they die of old age? currently about 1 year old. I would prefer to harvest only 1/2 dozen at a time.
