What kind of tail does my goldfish have?

Question

I have a telescope/globe/dragon eye (which ever one you like to call it) goldfish. I always thought that mine has a double tail fin. But it ended up that he only has one...I'm not sure what kind of fin type this is. It is like a upside-down triangle and always flat when he swins or just drags down when he stops moving. I always thought that maybe when it grows up (since its only 2.5 inches and I've only had it for about a week) the fin will turn out like those butterfly tail types. Does anyone have this kind of tail type with their fancy goldfish? Don't get me wrong, he is my baby, just curious if there are actually other tails like his.

Its like a big skirt flowing at the back

Answer 1

Yes, that is called a forked tail and it sounds as if you have the veil version. Here's a link to similar fish and some more detail
