St. Thomas Mushrooms are a beautiful species covered with big bubbles which almost make them look like bubbletip anemones. They are hardy and easy to care for and come in a assortment of colors. St. Thomas Mushroom is also called the Warty Corallimorph, or the Caribbean Bubble Mushroom. It is wild collected and offered as single polyps. It's totally unique in it's bubbles, colors & patterns! These are loose polyps and are not attached to any significant amount of substrate. They will eventually attach to any clean substrate in your tank, or you can epoxy or superglue them to what ever you want. As a member of the Rhodactis genus, it takes a beating and can easily be fragged down the middle with a brand new razorblade or coral bandsaw.
Water Flow and Lighting
St. Thomas Mushrooms Corals are all easy to maintain in the reef aquarium. They prefer a low to moderate water movement, and a low to moderate lighting level. Lighting can be Power compacts, T5's, LED's or even Metal Halides. All lighting can grow Mushroom Corals as long as the proper level of light is provided. If a Par meter is available the appropriate lighting level is anywhere from a Par 80 all the way to a Par 200. Which is a wide range of acceptability. For lighting spectrum use between a 14-20K color spectrum for your bulbs for best coloration.
>All mushrooms are semi-aggressive and require adequate space between themselves and other corals. Placement can be any where in the aquarium as long as it receives adequate water flow and lighting levels and leaves enough room around your corals that they have room for growth without infringing on another corals growing room or lighting.
Diet and Feeding
Mushroom corals receive the majority of their nutritional requirements through the process of photosynthesis, which simply means their lighting creates symbiotic algae called zooxanthellae in the body of the coral which provides its nutrition. We do recommend providing supplemental food such as micro-plankton or foods designed for filter-feeding invertebrates.
