Green Ricordea Yuma, commonly called a Flower Mushroom Coral, is a member of the order Corallimorpharia. It has beautiful features of short, club, or berry-shaped tentacles. It shares some resemblance to stony hard corals, and is also called a Disc Anemone as they are close cousins of both corals and anemones. It is found in a variety of color forms, but green is the most common Ricordia Yuma.
Pacific yuma can be sensitive and challenging so we do not recommend them for the beginner
Water Flow and Lighting
Pacific Yuma require a low to moderate water movement, and for their health they must be placed in an area that will keep the lighting at a low level. Otherwise they will not do well over the long term. Lighting can be Power compacts, T5's, LED's or even Metal Halides. All lighting can grow Florida Ricordea Mushrooms 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 to a Par 150. Which means they need to be placed in an area where they are shaded or kept from receiving direct light. If after a few weeks your Yuma are reaching toward the light, move them slightly toward the light. Do not change there position very much. After another few weeks see if they are good or reaching. Keep working with your Ricordea Yuma till they are in the perfect position. 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. If after a few weeks your Yuma are reaching toward your light, move them slightly towards the light. Do not change there position more than one or two inches. After another few weeks see if they are good or reaching. Keep working with your Ricordea Yuma till they are in the perfect position. For lighting spectrum use between a 14-20K color spectrum for your bulbs for best coloration.
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.
