They thrive in groups and do best alongside other peaceful species of similar size. Good tank mates: balloon mollies, guppies, swordtails, corydoras catfish, neon tetras and other small tetras, rasboras, otocinclus, peaceful gouramis, nerite snails, neocaridina shrimp (with cover). Avoid: aggressive cichlids, large barbs known for fin nipping (e.g., tiger barbs), and any fish large enough to swallow a 2–3 inch platy.
