I believe over year ago a story broke out about Hawaii boycott selling Yellow tangs and other fish to Petco. I wrote a post over a year ago about same thing about their fish. Only answer was stop shopping there. Big chain store for at least for fish department is a complete failure. Only thing Petco is doing is showing you if you don't know how to run a saltwater System. This is how you get ick and sick fish. Only thing they can do is sell dog, cat ,bird stuff. I blame wholesaler that sells they fish to Petco. Shame on them. I heard they not allow copper in there system and don't have hospital tank either. I used to look at their bettas and even those are sick and to small. Terrible .....
