Stocking a 29 gallon biocube????

[eveningstar15]

I have a coralife 29 gallon biocube. Coralife protein skimmer, heater, 20lbs base rock, 10lbs live rock, 2" live sb, intank media basket with filter floss, purigen, chemi pure elite. Right now I have 5 astrea snails, 5 dwarf ceriths, 5 dwarf blue legged crabs, and a porcelain crab. As for fish I have a yellow rose goby/candy stripe pistol shrimp and a yellow clown goby. I am wanting to get another small fish (max size 2in). I want something that is active and not going to hide all the time. Anyone have any suggestions?? In the future I would like to add 2 false clowns. Are clowns more aggressive if there is two of them. Would that be too many fish? Would it be better to just get one false clown??

I got a chalk bass a few years beach because my fiancée begged me for him. At first I hated the thing but now he is one of my favorites. Very colorful, active, always begging for food. Down side to you requirements is they get 3-3.5"
