Marine Fish sometimes has some rare species. I was there about two weeks ago and they had Two Gold Heart Triggers. That is a very rare fish I have been told. I was told there that there are only 10 in the U.S. and Marine Fish had 5 of them. I only saw two. If you ask me thats a pretty rare fish. They can order you pretty much anything you want I would think.
I have a book called Clownfish. Imagin that, and they have alot of different rare clownfish in it and I beleive that one is in it. It has the great barrier reef clown I know that. I would recommend it. It also talks about there care.
