The Pacific Yuma Mushroom – Ricordea Yuma is one of the most colorful corals in our hobby. It is sometimes mixed up with Ricordea Florida, that looks almost the same , but has some differences in the positioning of its buble bumps.
Most have two colors but there are many with one color and a few with pallete that is envysome by many! Red, green, tan, brown, translucent, grey, blue, orange, purple, pink…. any color really can be in the mix.
Often there is a main color of the discus, a color of the mouth, another color in the bumps, and a few have an extra color in the pumps around the mouth that can be the same with the bumps on the bumps on the edge of the discus.
Like all mushrooms it is round with a very short stalk. It has bubble like bumps radiating in rows leading in to tis mouth. The bumps close to the mouth are sometimes larger. The bumps on the rim of the discus are sometimes longer.
The radiating positions of the bumps and the closeness to the mouth are the main discernable differences of the species.
Looking close to the mouth area you can sometimes see if it tends to divide. The usual shape of the mouth is a slit, here you see a second slit forming.
This coral benefits from peace and quiet. A slow cuttent is best, it will tolerate near stagnant current and medium flow.
It does not need too much light. If acclimated to non-harsh strong light , it will tolerate it. Low and non-reef lights are also possible, but not perfect. Medium light is best, when in a high light tank, put it in relative shade or close to the side glass.
The mouth can extend to eat a rather big meal. A 1cm piece might be pushing it, but it will probably handle it. Smaller pieces are lead to the mouth slowly through its mucus movement. It may lose up to digest its food, and may expel its guts into the enclosure the closed-up discus makes. This may be to help with digestion.
It usually grows to 5cm diameter. It multiplies by dividing, and less often by pedal laceration.
It is best to wait it out to make new individuals. It is not famed for its durability after it has been cut – though it is doable.
I got these!
Orange, on deep purple body, pink skirt and green mouth
I got 3 of them, one is a prized specimen, the second is a smaller cousin and the third…. I am attempting to save if from the jaws of death!
