well not to discourage you, but maybe consider a smaller fish. If you put perculas instead you could expand into other fish such as basslets, gobies, or even chromis.
I have:
1 royal gramma
1 YT Black Chromis
1 YT Blue Damsel
2 Blue Damsels
1 Green Chromis
I am very happy with my tank, but i am trying to remove the damsels to put in firefish (much nicer)
