I had some a few years ago pre-move, likely wild caught. Really nice fish but a tiny bit nervous, they can be jumpers. I haven't read how captive bred coloration looks when adult. I did see something about "gold denisonis", a hybrid with a close relative, I think. I hope breeders are NOT going there, denisonis are so pretty, we don't need "gold" or "long fins"... or please not "balloon".
Yours do look like s. denisoni to me...I'll be interested to hear (& see) how yours color up, captive breeding is important to keep wild populations sustainable but inbreeding & mutations, meh.
