I'm dying for a clam, a Blue Maxima I think it's called. I have a small, 2" ish Coral Beauty Angel in the tank, a 90 gallon. Am I safe or will my $20 fish kill my $50 clam? Also in the tank is a Mandarin Goby, a Yellow Watchman Goby, 2 Perc Clowns, a Tomato Clown, and a CUC including a Coral Banded Shrimp, some cleaners and a Peppermint. Any concerns in there other than the Angel? Thanks!
