Compatibility brief
Can Molly live with Platy?
Often a workable match in a suitable, well-run tank. Still verify behaviour in your setup.
In many setups, Molly and Platy are often kept together in a suitable peaceful community when temperature and pH are matched and the tank is sized for adults. Individual behaviour, filtration, and layout still decide whether it works in your home.
