black swordtails

Question
what fish do the black swordtail get along with?

Answer
Hello Jillian,
The only fish I wouldn't put swordtails with, is 2 males together, not that they would fight, but if females are there would be competition. Unless you have a large tank and 2-3 females per male.

Other than that swordtails are one of the best tank members as they don't pester any of the other tank mates.
