The Hairy Mushroom, Discosoma sp., also known as the Furry Mushroom, is a species of Discosoma that is covered with an abundance of hair-like tentacles across its usually brown/tan body. The Hairy Mushroom is particularly a good choice because it does not require specific tank alterations to thrive: it needs moderate waterflow, moderate lighting, and can be placed in the bottom or middle of a tank. Further, the Hairy Mushroom can be a proficient colonizer as it tends to frag very quickly. This can make for good fun watching your Hairy Mushroom expand across your tank, or it can be a colonization that you might want to control. Due to this, you should not house the Hairy Mushroom directly next to another sessile organism. It feeds photosynthetically through the zooxanthellae living within it but will also benefit from supplementary feeding of meaty foods. The Hairy Mushroom is a great addition to most reef tanks, especially for beginners as it is relatively easy to keep in the home aquarium.
