overstocked
too many gobies if you want 2 firefish get either two firefish or two purple firefish. neon gobies are tiny though they are cool. I have heard other people say their neon gobies got stuck in their filter. Dont put a royal grama in with a dottyback (the psuedochromis) choose on of the other. Clowns might pick on gobies. I wanted a horseshoe crab also until I learned they will grow to be as big as the ones in the wild. (hopefully you know how big those are) Instead of getting a coral banded shrimp I would get a peppermint shrimp or scarlet skunk cleaner shrimp. also porceline crabs are a nice addition to your tank. hope this helped
