Aquarium Filtration
Use an efficient filter that provides reliable biological filtration and moderate water movement. Regular partial water changes help maintain stable water quality and reduce waste accumulation.

Moderate LED lighting enhances the Rose Velvet Molly's warm colouration while supporting healthy plant growth. Maintain a consistent day–night cycle.
Aquarium Heating
Maintain a stable temperature of 24–28°C using a reliable adjustable heater and thermometer.
