I have 30 - 40 adult tilapia available for an Aquaponics system. They average about 12 inches in length. They are white / pink in color and are over two years old. Please contact me with any questions. I have to get rid of them to start construction on the breeding room. I am somewhat flexible on the price in order to find a good home for them. When purchased they were $150 including delivery and where about one inch each. I would accept less that that. Ty for looking.
