Skip the small clam as well. Smaller clams have more complex requirements that you might be better off avoiding while you're just getting into it. Down the road however you might want to try a clam that is at least 3", croceas are good little clams, often coming with lovely blues, purples, and teal greens.

Regardless though, you're probably a year out from after you switch your system over from adopting a clam.
