I have a hunch that they both may be female, however one (the one I was told was male) has less of the feminine characteristics. The colour on the female is not as vibrant as it normally is, however, she usually has more yellow on her face and back, and brighter spots on her dorsal fin than the male. the male is also quite a bit larger. I am only guessing genders from what I have been told so I could be completely wrong:;dk. Male (or so I was told) View attachment IMG_2642.jpg Female - she normally has far more purple on her belly.
