Hi, this is the 4th day i use copper on the blue tang and clown, still looking good, blue tang refuse to eat for 4 days no matter what pellet i throw in, today i remember i still have frozen mysis, so i throw in and he eat like pig!!!!
If you need copper pls do not buy, i can give you some, bought from sealife they mixed for me and it a big bottle, use 2 years also cannot finish, hahaha.
