it looks like it could be a cross of some kind is that him flareing? he kindos resembleds a veil tail but his fins are much largers. he's a beutiful fish
Looks like a cross between a Deltatail and a Veiltail. It has almost got the shape of some they are calling (heart tail) I think thats what they call it. Basically mixing 2 different types of tails. The thing is, they don't reproduce the same types of fry.
It looks more like combtail to me, a cross between a veiltail and crowntail. You can tell by the tail shape, the small spikes. Not long enough to be a crowntail and not short enough to be a veiltail.
