thanx. the hippo is new. got it for $35 at lfs a week ago. i had a real small one b4 long time ago that didnt make it after 2 days. i think that was bc my system was very new at that time. now, i feel i can pretty much put anything in it. i need to pimp up my 150 fowlr b4 i take pics of it. that tank is being neglected somewhat.
