Yesterday I saw a jet black angel about 2 inches in length at the LFS. It was listed as a "black" angelfish. I tried to find the same fish on the internet and what I found is not the same fish. At saltwater.com the black angelfish actually has white vertical stripes. Does anyone know of a jet black angelfish and if so does it stay that color, adult size, minimum tank size?

Thanks for any help you can give me on this issue.
