Additional Notes

Can get harassed by Clown Gobies, Blennie's, shrimp, most Angel fish and Butterfly fish. == Look out for snails attacking your clam, they are very small 1-4mm found around the mantle and devour your clam. They are a pain to destroy, as far as I am aware these little so and so`s do not have many predators, the six line wrasse will have a good look but mine will not touch them. It comes down to a torch after lights out and a good pair of tweezers to pick them off.
