Hey, how long did it take yours to reach 7 inches?Mine only hangs out at night. I never see him during the day. However I do know that he is doing his job since the tank is realatively clean and when I do see him he has a nice fat belly. He has been in my tank for more than four years and he is about seven inches long.

Mine seems ot have stopped growing at around 5''.. he's maybe 2 years old. Very healthy fish though
