Ricordea Yuma is a corallimorph known for its large mouth that dominates the oral disc and the rounded, ball-like tentacles that spiral outward from the center. Because it doesn't build a hard skeleton, it has a soft, undulating form quite different from stony corals. It's commonly sold in vivid, fluorescent color morphs that stand out in any reef display. It moves little and has a calm temperament, rewarding careful attention to water quality and lighting with slow, visible changes in color and tentacle spread. As an intermediate-level species, it's best suited to keepers who already have some experience managing a reef tank.

About Ricordea Yuma
Ricordea Yuma is a corallimorph with a large mouth and spiraling, ball-shaped tentacles. It builds no hard skeleton and is often sold in vivid fluorescent colors. Considered an intermediate-level species to keep.
7 things to know before welcoming a Ricordea Yuma
1Lighting & Placement
Ricordea Yuma tends to settle in well under moderate to slightly subdued lighting rather than very intense light. Placing it in a spot shaded by rockwork or in the mid-water column, away from direct high-intensity light, often helps it stay stable. After placement, watch how its color and disc expansion change and adjust its position if needed.
2Keep Water Flow Gentle
Prolonged exposure to strong flow can cause the oral disc to close up or shrink. A gentle, steady current helps it stay open and display its tentacles naturally. Periodically check and adjust the direction of your pumps.
3No Hard Skeleton
Unlike stony corals, Ricordea Yuma doesn't form a hard skeleton. It grows and multiplies by splitting rather than skeletal growth, so keep that in mind when deciding how to secure it in your layout.
4Give It Some Space
Corallimorphs like this one can affect neighboring corals or livestock through their tentacles or chemical interactions, so it's safer to leave some distance between it and other specimens. Placing them too close together can affect each other's growth and health.
5Feeding Is Optional
In nature it's thought to supplement photosynthesis with small captured food particles, but many specimens do fine without deliberate feeding. If you do feed, offer small portions sized to its mouth and watch how it responds before continuing.
6Stable Water Quality
As an intermediate-level species, it can struggle with extreme swings in water parameters. Keeping a consistent water change schedule and avoiding sudden changes is key to keeping it healthy long-term.
7Add It to a Mature Tank
It's reassuring to confirm your tank is fully cycled and stable before bringing one home. Treat the period right after placement as a settling-in phase, watching for changes in color and disc expansion as it adjusts to its new environment.

- A.Very intense lighting isn't required, and it often does well under moderate to slightly subdued light. Adjust the lighting based on how it responds after placement.
- Q.Do I need to feed it?
- A.Feeding isn't strictly necessary, and many specimens do fine without it. If you choose to feed, offer small portions sized to its mouth sparingly.
