frag section fish?

Some larger pods can annoy corals, especially zoas. Wrasses also help keep flatworms and other bad critters under control. I guess I should have been more specific, since I would not recommend a mandarin or anything like that.

A blenny is a great idea. I have a bi color that's been great. Small and hardy

I cant see a reason to keep one in their, this will be in the sump of your main display so their will be enought nutrients comming from the display not realy needed IMO but if you must a wrass would be a good bet
