Experienced breeders can do what they want IMO. They know what they are doing.
spade tails are pretty common, they are not uncommon at all, i've seen many before
No baby bettas. I don't have anywhere to house the girl (gourami tank, livebearer tank, fry tank) and my mom might kill me of I get anymore fish. I have to figure out what to do with the ones I already have when I go to college in August. I'm taking my betta, but the rest need new homes
