Thank you, Lil, much appreciated. That was exactly the sort of critique I was looking for!
I couldn't get a full flare shot, as she moves too fast when she is riled up. She is for sure a female as you could clearly see through her when the black spread was less. I think she might actually have been a fish from a HM spawn that the breeder had mislabelled or perhaps a HM x HMPK cross. The fins are pretty long when she is not displaying too.
I've kept a lot of my females jarred/isolated and I think it definitely makes them more willing to flare and display like a male would. Panda even flares at fingers and pens, not just a mirror or other fish. They're too feisty though. I had just turned my back one time and I guess Panda had jumped the divider and was having it out with the female next door. The notch seems to be permanent so far, much to my annoyance, but it is worse on the other girl... Looks like the entire top of the dorsal just got chopped off. >.>
I would like to breed her to a decent veiltail to get a black marble VT line started. The male I have isn't anything particularly special, but he a dark bodied yellow bicolour without irid ("chocolate" is the term, I think?). I would also like to have regular HMPK line, but didn't really know if she would be any good for that (I just lost recently what I thought was a very well formed HMPK female and so had to rework my plans).
