Okay, I've completed my stocking list for my 40 gallon. 4 or 5 blue/green chromises, 2 tank raised percula clownfish, 1 neon goby, 1 cleaner shrimp, 3 or 4 pajama cardinals, 40 blue legged hermit crabs, and 3 or 4 turbo grazer snails. And 1 or 2 other types of small inverts. Is this too many fish and inverts? Are there any other fish I should choose over another?
