Care notes

Livebearers; breed readily. Tolerate some salinity (brackish adaptable). Prefer alkaline water. Males may harass females—keep 1:2 ratio.

Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
