ok. I happen to be retarded when it comes to dimensions. So 20x20x20 to me just sounds like.. a fairly decent sized tank hahah.. how about in gallons?
Anywhoo... your fish list so far is what I have in my tank, 2 percs, 1 bi color blennie, and I also have a yellow watchman.
I'd say choose an active fish, one you will see... if your liimited to the amount of fish you can have.. then yeah, choose an active fish you will see out in the open all the time. I am not sure what to recommend... perhaps some kind of wrasse or goby???
