Hey everyone, I'm getting a frag tank built right now that will be 22x27x11" right around 28-29 gallons. I'm going to have a frag rack on the left 2/3 of the tank that will be propped up leaving space under it and on the entire right 1/3 of the tank.

I'd like to keep a fish or 2 in here, anyone have any ideas? I've read a lot about the sixline's in frag tanks but don't really have any pest issues for them to monitor. I'm looking for a cool fish or 2; any ideas?

I originally thought about a pair of clowns an a nem on the empty side, thoughts? Opinions?
