The thing in the front is a Alligator pipe fish.
I feed him plankton, and at the same time I feed the others flake food so there is no real problem.
The tank has been set up for about 2 months now, but I used sand and live rock from a small FOWLR tank I had going for about 2 years.
I have had the clam for 2 weeks now and hes doing great, hes almost always open.
As far as the pipe fish, I like him because he looks kind of like a seahorse, but hes a community fish, nice addition.
