WYSIWYG TRUE Rainbow Yuma Mushroom (Ricordea yuma)

You are buying the exact coral in the photo. This is a true rainbow Ricordea yuma, and it shows the full range of color a yuma can carry. Under blue spectrum reef lighting the outer ring is made of large, rounded teal bubbles. Moving inward, the bubbles get smaller and turn orange and copper, packed tight around the center. Bright neon green glows in the tissue between them, and the mouth is a raised orange-red cone with a glowing yellow-green slit. Teal, green, orange and red on one mushroom is what makes a yuma a true rainbow. Conditioned in our Key West systems and photographed in our showroom.

About Ricordea Yuma (Ricordea yuma)

Ricordea yuma is an Indo-Pacific mushroom covered in rounded bubble-like vesicles instead of a flat disc. It is one of the most sought-after mushrooms in the hobby because of how much color a single polyp can hold. Multi-color rainbow yumas are uncommon, and each one is different, which is why they are sold as one-of-a-kind pieces.

Care Guide

Easy to moderate care. Yumas reward lower light and stable water with full inflation and richer color.

Lighting: Low to Medium — PAR 50–150. Too much light can shrink the bubbles and fade the color.
Flow: Low — gentle flow keeps it open and inflated.
Placement: Sandbed or shaded lower rock.
Feeding: Low — it lives mostly on light, and will take small meaty foods placed on its mouth.
Aggression: Peaceful, but keep it a few inches away from other corals so it can spread.
Water Parameters: Temp 76–78°F, salinity 1.025–1.026, Alk 8–9 dKH, Ca 420–440, Mg 1300–1400. Stability matters more than exact numbers.
