I have a single veilttail, because I raised it from a petco baby betta. He is PURPLE, so I love him. A nice purple is hard to find, because its red with an overcast of blue, which you can't see unless he holds still and you look up close.
I prefer beautiful colors regardless of tail type, but I'm less likely to buy a veiltail colorful or not.
I also have a HM plakat, crowntail, delta tail, and three females(two crowntails, one ...delta tail?). I like plakats, halfmoons, and deltas. My mom Loves crowntails.
