I really like those dumbo bettas with their big white pectoral fins. All that I have seen have been white and purple and I really want one but $20 is just too much for one betta I think.
But I might splurge someday and get one anyway. Hopefully they'll eventually come down in price like the halfmoons finally are. My local pet store sells both dumbo plakats and dumbo veiltails, For some reason they are always purplish and the "ears' are white. I've never seen any other color but they look really nice in purple anyway.
