Hello! First off thanks for taking the time to look at my post. I bought these salvini a couple months ago they were only about half this size. I would like to know if i have male or female. Im pretty sure from what i read the one with the black on the dorsal fin is a female. The other is the one im not sure of. Im adding multiple pics of the same fish so you can have a good view. It has great colour and not dull like they say males tend to be. Also I see some black spots in the dorsal fin just not a prominent stripe. Anyways i look forward to yalls opinions! Thanks again.
