Hey Guys,
I bought a Atlantic blue Tang on Tuesday. Looked good in the shop for the last week and I brought him home. He is in a QT tank that I use. I have used copper in it but I cleaned it out really well when I heard that copper is not good for tangs. I have 2 bubblers in it and a sponge filter. Put new water in and acclimated him. Water is at 78 and 1.021. he is eating really well swimming very active. Today I noticed this spot on him so i am still new to this with almost a year under my belt. I have no idea what this is please help. It is blackish and swirly.
