Rhodactis (Rhodactis sp.)mushrooms are a diverse group of mushrooms that are loved by beginners and advanced hobbyists alike. They come in a variety of colors and sizes and some of the species, like the Bounce mushroom with their brightly colored bubbles are one of the most popular species on the market. They are native to the Indo-Pacific. When placing them in an aquarium, they should be placed in an area where they will experience moderate light and flow. It should be noted that they are able to release their foot and move around the tank, settling where they feel best. They contain a symbiotic algae that provides them with a source of food, but they will also feed on a variety of foods placed in the tank such as phytoplankton, or coral food. Before adding a mushroom to the tank make sure to dip it and then acclimate it. As a note, when mushrooms are irritated they can produce a mucus that makes them difficult to hold. That mucus can also be dangerous if it touches sensitive skin or is ingested by humans, cats, or dogs.
