yah the biggest salt water tank the fish store that i got it from was 60 gallons and they didnt realize that a Queensland grouper grows fast and big until it arrived and they saw what they know it to be called a bumble bee grouper . my tank is 480 gallons and i know that wont work forever but its only 6 inches now and it was almost free so i couldnt say no . i figure i have a couple years before i have to call sea world . thanks for all the replysJakob;3461564; said:Nice Queensland grouper.
