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.

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.
