hotsauce;3346418; said:they get very big, easily 12-15" first year. i started mine in a 55gal and it lasted all of 6 mnths. max out around 30-45" and 40-60lbs. starters tanks for these fish is no such thing. they are fast gowing and at minimum get a 100 gal or better a 150 since they are wider. it would last for years
