Many fish stop growing in a tank and some just keep growing. I usually keep hipp tangs and copperbands about 10 years but they never get to big. Maybe 4" and they remain healthy. But if I take a local flounder or sea robin and keep it, they get huge in a year or two. I once had a remora and I could almost hear the thing growing.
It grew to about 10" in less than a year and I gave it to the New York Aquarium.
