They're beautiful! My female is huge and the males are just starting to crest up. I love this species, they're so easy to keep and you really can't beat the males in the breeding season for eye popping colours!
I've been a voyeur on this post, just wanted to say I've been enjoying the progression of these guys and all of your updates!
