Thanks guys! It's fish only with live rock. It's somewhat of a practice tank, and if things go well I'll move to reef setup in a couple years. That'd be with an entirely new setup though, so I'm not too worried about the conversion to reef until it happens.
Substrate is play sand, bought at Lowe's, about 3" deep.
I put the clown in last night... my first!
It was fun watching the little bugger keep swimming at the powerheads, seems to be his new hobby. I do kind of feel like he needs a friend though, seems like a lot of empty space and I'm not sure if the fish get lonely.
