hmm that's interesting about your thoughts on the dorsal spike, he's a pic of my previous pair. I witnessed this pair spawning, but the female unfortunately ate the eggs
First the male
And the female
A couple of things i thought were interesting comparing these pics to Billaney's and my above unknown pair:
Billaney's male has a large dorsal spike, my male in the pic above demonstrates a large dorsal spike but my female's spike in the above pic actually appears larger in proportion to the other dorsal rays. My unknown male which i'm going to call X from now on has a very sport spike.
My male in the first pic has a black matte spot, with slight blue flecking on the outside, X is similar, Billaney's male i can't tell due to the angle of the shot
Billaney's male, my male and X have longer pelvic rays, the females in all three pics have blunt pelvic rays shorter in length.
All three females demonstrate a pinkish hue behind the pectoral fin, this isn't evident in Billaney's male, my male and X
Billaney's female, and my female show a small black smudge behind the main black dot which isn't shown in either pics of the known males. X shows this black smudge in one photo but not the other??
So just some observations, I'm still pretty unsure on the what sex X is, maybe it's a transgender fish :lol: or a hemaphrodite!
I thought this would be any interesting discussion so if anyone else has pics of their known sexed pairs please post them up so we can compare
