I sent an email to the seller (breeder). Hopefully get a reply and the and some clarification. I'll try and get better pics this weekend.Mcasella said:They look like black blushing angels, but they could be pinoy blushing (blue-black, is someone says blue pinoy they don't realize pinoy literally means blue-black for angels). They are nice looking really long fins.
