I have discovered some weird little creature in my reef tank. He is about the size of quarter(except he is oval), flat like a flounder, black with several white spots on his back and two antenea-looking things sticking out fom his head(?).
I have several pictures, none of them very good, as he likes to stay somewhat hidden and is hard to photograph. I will post better pictures if I can get some.
Thanks for any ideas you may have.
