I've not decided entirely yet. My list of potentials so far is:
Two young slightly different clowns that are young and see if they will pair up.
White or Yellow Banded Possum Wrasse if I don't get clowns.
Court Jester Goby
Green Clown Goby
Purple or a young Helfrichi Firefish (Maybe a pair)
Zebra Barred Dartfish
I don't know about the clowns because if I get them, I will feel limited with additions due to the semi aggressive nature and the size of the tank I have, (not to mention that they get somewhat large)
