I want to get a pair of Banghai Cardinals. I have a 10g tank with only one firefish in it plus the usual live rock and 2 peppermint shrimp. Would the BC's be "happy" in a 10g? I give this consideration because they seem to be the sort of fish that don't need a great deal of swimming room. All the BC's that I have seen usually just hang around and don't move around much at all. I can move the firefish to another tank if necessary. Also, I understand that the sexes of these guys are indistinguishable. If I got two younger ones will one of them change sex if necessary to become a pair like clownfish??
Thanks in advance for any advice on these fish.
