I know that there was a small blue-clawed pistol shrimp in the tank, but I would asume he would've eaten the even smaller yellow clown goby??? And I know that three fish to a ten's too much, but I'm building a stand for my 7bow as we speak! ;-) They were very small a good price and I was trying to get a little excitement in my ten till I got my 54bow finished. (hint-hint dan) I do have a few nassa. snails and alot of bristles, so if they died behind the rock, it's possible that they were eat'n??? but still no clowns, Harry and Loyde will be missed:(
