It really depends what fish it is. I have a longfin bristlenose and I love the flowing fins. I also like butterfly koi’s. Now if it was an Oscar or tiger barbs, then no.
Looked these up. They are incredible. Those swordtails are far beyond any betta or goldfish. Can't decide if I love them or hate them.fire cracker sword tails are really nice.
not sure what you mean by longfin bettas, do you mean halfmoons?I don't like longfin bettas, but otherwise I like longfin fish.
