Moses,
How are the black muscles doing? I bought some that looked like that at the grocery store ...not too smart. They were cold water muscles and they didn't last very long at all.
What beach did you get yours from, Maine, Florida, San Diego? I called "Your Reef" about the green lipped muscles but he said that he didn't ever get requests for them. I had some a long time ago. That was before I could feed the tank like I can now so I might be able to keep them alive. Are they tolerant of tropical tanks?
Also, does anyone have access to barnacles that are from warm waters? I think they will be happy in well fed tanks. I like the way that they feed so actively. I wish that I could get some of the living ones that are big and purple like the dried ones that are available for decoration or homes for blennies. Anyway, barnacles would need to be attached to something that can go into the reef tank unless they could be found in a large clump.
Oh, I bought different types of the clams from the sea food counter and most of the them are doing quite well after a year. Some have a better chances than others. Perhaps 60% are still around and are growing. They aren't very pretty sitting on or burrowing into the sand but at 2 to 5 bucks a bag, they added some variety to my stark new tank when I started it up.
We have talked about brittle stars. What other critters could be collected, in warm waters like Florida, that we are passing up? Divers aren't that expensive.
