Hmm...Daisy, I would have bet foreground green is male with those long dorsal & anal fins...unless than lonngg dorsal is an optical illusion (or streak on the glass? a pic thing? I think not)
Still anal fin is way too long for female. Of the 3 adult sevs I guess the gold is most likely female with fins & chubby tummy too, but the background "lurker" has similar fins.
Your fish are breaking all my "rules" of cichlid sexing, lol! I'm always willing to admit I'm wrong. But have you actually watched who lays the eggs & who fertilizes them?
