These images aren't the best, the front of his tank is dome shaped, so it makes it difficult to get a good shot. As for his fins, he has obviously developed a lot of "spikes," and he is now getting splits on his tail fin. I thought he had stopped developing but these splits just started showing up a few days ago! I guess he's a veil tail, but his tail fin doesn't seem to totally fit that bill so he's probably a cross. I don't know what other tail shape you'd call that!
The first picture is taken with flash, and the second is without. I thought I'd add both just to get the best perspective. Let me know what you think on his tail type!
