Of those, you could easily get the Percs, Firefish, Blenny, Crabs, Peppermint shrimp, Royal Gramma, Strawberry Pseudo, and the Blue Damsel, but not all together.
Maybe 2 Percs, a CUC including crabs, Firefish, Peppermint Shrimp, and maybe a Royal Gramma (Somebody correct me if this is overstocked).
Fish to AVOID
in that tank:
Yellow Tang (Size)
Mandarins (Specialized diet on live pods, need larger tank to hold LR)
Jewel Damsel (Size and Aggression as a damsel)
Coral Catfish (Size)
Sea Slug (Hard to care for unless it is a certain kind, hard to tell)
Valentini (Nipping and size) MAYBE
Blue damsel (Aggression)
