It's the two clownfish, they are the black ones with white stripes. No coral or anything. Early on I had some of the tiny hermit crabs and a snail but they all passed on after 2-4 years. The two clownfish have dug out a little 'home' for themselves by removing some of the sand around a hiding area that is created by the live rock and seem quite happy.
I'm in Washington, DC, in the Adams Morgan area. Please let me know if you're interested!
