I was in a thread the other day about Petco, so I decided to stop by my local one. Decent selection of SW fish, they had quite a few blue tangs that might have been an inch long ! Hope folks know how big they get. They did have some emerald crabs also, I almost got one, But decided not to. I have film algae in the DT, not sure if it would have decent food supply. Stuck with my salt purchase .
