Where to start?....
Sixline wrasse, Shrimp gobies, firefish (they jump, though, so watch out), some of the cardinals, a great species tank for dottybacks, skunks or ocellaris clowns (tomato's, clarki's, and marroons can be aggressive if you want any other tankmates), some of the tiny basselets, little gobies like the twinspot, rainford's, etc, etc. :wink: HTH
