Help!! My clown fishes are dying.
My girlfriend and I are new to Marine creature. She bought 5 clown fishes and I bought another 5 for each of our houses. We got them from the breed center in southern part of Thailand.
At my girlfriend's tank, 2 weeks after they were past away, then the last one that i got left shown a sign of white stuff and it is eating its tail. When I compare with my tank, all survive perfectly.
I don't know if it is causes fungus or bacteria. I noticed that my girlfriend put her hand into the water to arrange live rock and small coral 4-5 times a week. Can any one tell me what happen? And how to cure....she seems hurting and I want to save her.
