^ not necessarily actually, females can be just as pretty, though in most cases the male is more... obvious...
Female- there is a "tail" type where the male has the SAME short fins:
Female- Tihs Vieltale - multi- colored
Female- Wildfire Vieltale - orange
Butterfly male- Flagg (Viel tail type)
Multi-colored male- Pickle (Spade tail type)
But there are also different fin types:
Hurricane - green and red
There are also, Halfmoons, Deltas, Plakats, and Super Deltas, but I have no pictures of them...
