The Calvert Marine Museum has a tank that has what looks like an oyster bed with the striped blennies in there but I believe that they are the only species that live in that tank. They use oyster shells as their reef but I doubt any are alive. I may give them a call or an email and ask them about what parameters they maintain the tank at and some tips about collecting specimens. It's a cool tank! If you're down that way you should stop in and see it. They also have a terrific marine fossil collection.
