I'm still way off from stocking my tank but have been thinking about the inhabitants. I've always liked Anthias, so I've been reading up on them a bit. I'm looking in to some of the smaller 3" species, and noticing that they are recommended to be housed in a 120 gallon aquarium. I kinda find it hard to believe you need a 120 for 3 3" fish. Anyone have experience with these guys. If i'm wrong i'm wrong, but it just seems a little hard to swallow.
