Well I have 300 Watts of MH in a 18' deep tank and mine is doing great. Hmmm bruising... can I get a "fish whisperer" to come over and tell my clowns that are hosting in it to be careful :P
Though I have lost one in the past that was in the middle of the tank and bounced it way to the bottom >_< :cry .
Good luck with it when they settle in and puff out they are a center piece I think
