Ahhh lol, that's the fella.
I don't know if I got some strange mutant strain or what, but the ones I had weren't gray, but especially the males had an iridescent blue on the filaments and on the fin edges. I wouldn't call them feather fin pretty, but I never found them to be lacking myself.
I feel sorry for you if it's their first spawn. Once they start they aren't going to quit! No, it's a great treat to watch all the different generations interact with one another.
