mini pellia is a very undemanding plant just keep your tank healthy it will do good. It will do good in tanks with light as low as 1.5 wpg or 10 micromoles per second however it will do great in high light too the more light/co2/ferts that are applied to the tank the faster it grows.co2 is not necessary however it will grow about 30x faster with compressed co2 rather than without
