White & Yellow Polyp Toadstool Leathers are a hardy, easy-to-maintain coral; are easy to propagate and can grow very quickly into an attractive show piece in the aquarium. Toadstools are considered peaceful, beacuse they don't have sweeper tentacles; however, they grow rapidly and can release a toxin that irritates its neighbors, so ensure you provide enough space between these corals and their neighbors; for a safe introduction, give them a saltwater rinse after shipping and ensure your filtration has carbon. Toadstools can tolerate many non-ideal conditions, such as low light and high nutrients, although it is important to keep nitrates and phosphates low for the continued success of this coral. That being said, most will do best with a moderate flow/lighting and nutrient combination.
