Swordtails

Swordtails get their name from the males who have an extended lower tail fin that looks like a sword coming from their tail. Females do not have this extension.

Swordtails are community fish that can be housed with other peaceful, community species. They can also be housed with other swordtails and do best in groups of three or more.

These active fish that do best in small groups should be housed in a 20 gallon or larger tank to be suitable for their adult size.
