Thanks! I got individual ones of them, here's another of the whiter one. He has a cool red mustache, but I couldn't get a pic of it.
And the darker one. I love that he has large extra metallic scales perfectly evenly dispersed over his body. This is the best pic I got that shows them. He is so pretty swimming.
Overall, I really like their tail fin markings. I've seen a lot of them with nondescript tails, the markings on these give them nice definition.
