@ cosmicwitch, being a multi color it could be in any pattern. Luv there is actually my daughters betta, but over time I've kind of claimed him as my own. Our oldest betta & I think age is catching up with him. If your boy looks like him then I have to say you have quite a handsome boy on your hands!
@Horangi, without your boy in a full flare it's hard to tell what tail type he is. He could be a HM, but he could be a delta or super delta as well. If you can get a picture of him flaring it would be easier to tell. As for color, I'll have to let someone with more experience help you there. I don't have a clue, but it's a very pretty color, almost looks mint green.
