Why is my Yuma Ricordea shrinking and detaching?

Shrinking or detaching is usually a stress response to excessive water flow or excessively bright lighting. Relocate the coral to a gentler, more shaded area of the tank with low water movement.

How can I tell the difference between Ricordea yuma and Ricordea florida?

The easiest visual distinction is the mouth. Ricordea yuma has vesicle bubbles covering the oral cone right up to the mouth opening, whereas Ricordea florida has a smooth, bare area immediately surrounding the mouth.

Does Ricordea yuma need to be fed?

While they can survive solely on light via their symbiotic zooxanthellae, target feeding with fine meaty foods will significantly boost their growth rate, encourage reproduction, and enhance their overall health.

Will clownfish host a Yuma Ricordea?

It is entirely possible; some clownfish will readily adopt a large Ricordea yuma as a surrogate anemone. However, this can sometimes irritate the coral if the fish is too rough, causing it to remain closed.

Why is my Yuma mushroom turning white?

Turning white, known as bleaching, indicates the coral is expelling its symbiotic zooxanthellae. This is typically a severe stress response to sudden spikes in temperature or a rapid increase in light intensity.

About the Yuma Ricordea

Ricordea yuma is a distinct species of mushroom coral native to the Indo-Pacific. It is easily distinguished from its Caribbean cousin, Ricordea florida, by the presence of bubble-like pseudotentacles across its oral cone, reaching right up to the mouth opening. Available in a staggering array of vibrant, fluorescent colours ranging from neon greens to deep pinks and oranges, it serves as a spectacular focal point in the lower regions of a reef display.
