Thanks for all the suggestions.
I'm leaning towards getting a Banggai and possibly another clown soon, and then probably some form of a goby (neons look cool) and shrimp sometime later. I really want a mandarin but I've heard they are reaally picky eaters and do better in larger tanks so I decided against it.
Just another question, none of the pet stores nearby carry any of these kinds of fish. The one I usually visit only has clowns, damsels, and common fish of that type. I visited the other one that had a large variety in the past and they seemed to have either run out of stock or downsized their marine section. The main thing about buying online is the shipping, which will probably end up costing more than the actual fish. What are your experiences with getting your LFS to order fish for you?
