Platy Tank Mates

Platies are small, hardy, endlessly colourful livebearers — a forgiving first community fish.

Peaceful and undemanding, they mix with virtually every calm community species the engine knows. Like all livebearers they breed readily, so expect fry unless you keep a single sex. They prefer slightly hard water but tolerate a wide range.

Tank & group guidance: Keep a small group in a 10-gallon tank or larger. A trio of one sex avoids constant breeding; mixed groups should have more females than males. The planner below is pre-set to 10 gallons — add your real list to test it.

      Common questions

      What fish can live with platies?

      Most peaceful community fish: guppies, mollies, swordtails, corydoras, neon and ember tetras, and peaceful shrimp. Platies are easy-going and rarely cause trouble.

      Do platies need to be in groups?

      They are happiest in a small group of three or more. Keep one sex, or more females than males, to manage breeding and avoid harassment.

      How many platies in a 10-gallon tank?

      A small group of three to five suits a 10-gallon, remembering that they breed — plan for the fry, or keep males only.
