Euchema is a semi rigid non calcified macroalgae with irregular bumps. In our system we keep it under dimmed Fluval LEDs. It is found in nature in deeper water than most of the species we carry. We recommend placing it near the bottom of your established tank under lighting that would be suitable for mushroom corals which is low to moderate in intensity. Each portion is 40 cubic inches or larger. It can grow up to 1728 cubic inches in aquaria, but is easy to trim. The trimmings can be used to start new plants.
