A powerful filtration system is essential to maintain water quality, as Ranchus produce a significant amount of waste.
Ensure the filter has an adjustable flow rate, as Ranchus are not strong swimmers and need a gentle current.

Live plants such as Java fern, Anubias, and hornwort are excellent choices. They provide hiding spaces and improve water quality.
Avoid delicate plants that can be uprooted by the fish or consumed.
