Recommended

Established 30-gal reef

30+ gal cycled 6+ mo

Established reef with shaded/low light + low flow. Frag-friendly and spreads.

Photo coming soon
Ideal

Mature reef + dedicated mushroom garden

75+ gal / display rock with named morphs

Mature reef with named mushroom morphs in a shaded zone — Bounce, Yuma, Ricordea morphs reach show colour with stable params. Ricordea yuma (Indo-Pacific) — larger and more colourful than Florida ricordea; HIGHER light + feeding required.

Life & growth stages

How this animal changes through its life — each stage often has its own care, diet and space needs.

Photo coming soon
Planula larva

Corals begin as a free-swimming planula larva released into the water column after spawning or brooding. The tiny, ciliated larva drifts and swims until it finds suitable hard substrate to settle on.

Photo coming soon
Single polyp

Once settled, the larva metamorphoses into a single founding polyp that secretes a calcium-carbonate (or proteinaceous) base and extends a ring of tentacles to feed. Reef-building corals begin laying down skeleton at this stage.

Mature colony stage
Mature colony

The founding polyp buds asexually into a colony of many genetically identical polyps, building the species' characteristic growth form — branching, plating, encrusting, or massive. A mature colony can reproduce and contributes to reef structure.

Color & pattern variants

Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.

Natural
Rainbow Yumarepresentative

Rainbow Yuma

Multicolor morph with red, orange, green and blue vesicles on a single polyp — one of the most prized and expensive mushrooms in the hobby.

Orange / Redrepresentative

Orange / Red

Solid warm-toned vesicles with a contrasting mouth; a classic, vivid yuma color form.

Bean Bag Yumarepresentative

Bean Bag Yuma

RareIntermediate

A psychedelic striped yuma where the normally solid, bubbly vesicles each carry an erratic red-orange stripe or squiggle, giving a 'bean bag' patterned look. Young polyps emerge as plain orange yumas and only develop the signature striping as they mature.

Tip: Like all Ricordea yuma, this is best treated as an intermediate coral that needs stable water quality. Place it low in the tank under modest light (roughly under 100 PAR) with gentle flow so the vesicles inflate fully, and avoid moving it once settled. The striped pattern shows best on mature, well-fed polyps.

Frosted Nurple Yumarepresentative

Frosted Nurple Yuma

RareIntermediate

A bubbly yuma with frosted, pale-toned vesicles contrasting against a deeper colored body, the 'frosted' look giving it a soft pastel sheen.

Tip: Ricordea yuma is more sensitive than R. florida, so keep water quality stable. WWC recommends placing it low in the reef (under ~100 PAR) with low flow and target feeding roughly once a week to keep it plump and colored up.

Melon Hunter Yumarepresentative

Melon Hunter Yuma

RareIntermediate

A warm melon-and-green toned yuma with bubbly textured vesicles, named for its watermelon-like color blend.

Tip: Treat as an intermediate coral needing stable parameters. WWC advises placing it low on the rockwork or sand bed under low light (under ~100 PAR) with low flow; weekly target feeding helps it expand and intensify.

Watermelon Boba Tea Yumarepresentative

Watermelon Boba Tea Yuma

RareIntermediate

An extremely bubbly yuma with green-and-pink watermelon tones and round, bubble-tea-like vesicles that inspired the name.

Tip: As a more sensitive Ricordea yuma, keep water quality steady. WWC recommends placing it low (under ~100 PAR) with low flow so the dense vesicles inflate, and target feeding about once a week; avoid high-flow spots that flatten the bubbles.

Blueberry Boba Tea Yumarepresentative

Blueberry Boba Tea Yuma

RareIntermediate

An extremely bubbly yuma in cool blue-purple 'blueberry' tones, part of WWC's bubble-tea-themed line.

Tip: Ricordea yuma needs more stable conditions than R. florida. WWC recommends placing it low in the reef (under ~100 PAR) with low flow so the heavy vesicle structure stays fully inflated, with weekly target feeding.

Sun Scorched Yumarepresentative

Sun Scorched Yuma

RareIntermediate

A fiery yuma in scorched orange, red and yellow tones, named for its sunbaked appearance.

Tip: Keep water quality stable as this is an intermediate-level coral. WWC advises placing it low with low flow and modest light (under ~100 PAR), and target feeding weekly to maintain the warm coloration.

Honeydew Yumarepresentative

Honeydew Yuma

RareIntermediate

A soft green-yellow 'honeydew' melon toned yuma with the classic bubbly yuma vesicles.

Tip: As with all Ricordea yuma, aim for stable water parameters. WWC recommends keeping it low in the tank (under ~100 PAR) under gentle flow, with weekly feeding to keep it full and richly colored.

Berry Boppin Yumarepresentative

Berry Boppin Yuma

RareIntermediate

A berry-toned yuma blending pinks, purples and greens across its bubbly vesicles.

Tip: Treat as an intermediate coral that prefers steady water quality. WWC recommends placing it low in the reef with low flow (under ~100 PAR) and target feeding weekly to keep it plump.

Sunrise Yumarepresentative

Sunrise Yuma

RareIntermediate

A graduated orange-to-yellow yuma evoking a sunrise, with bubbly textured vesicles.

Tip: Ricordea yuma is more demanding than R. florida; keep conditions stable. WWC recommends placing it low in the reef (under ~100 PAR) with low flow and target feeding about once per week.

Buried Treasure Yumarepresentative

Buried Treasure Yuma

RareIntermediate

A large, multicolor yuma (specimens up to ~3.5 inches) with a treasure-chest mix of warm and cool tones across dense vesicles.

Tip: A larger yuma still needs the stable water quality this intermediate-level species demands. WWC advises giving it low-flow space low in the reef under modest light (under ~100 PAR) and feeding weekly to support the big polyp.

Golden Eclipse Yumarepresentative

Golden Eclipse Yuma

UncommonIntermediate

A golden-orange yuma with vibrant, textured vesicles that catch the light and sway in current.

Tip: While vendors market it as hardy, Ricordea yuma is generally an intermediate coral that is sensitive to poor water quality. Keep it low to moderate light with gentle flow and stable parameters; occasional feeding boosts coloration.

TRF Rainbow Yumarepresentative

TRF Rainbow Yuma

UncommonIntermediate

A multicolor rainbow yuma that shows predominantly blue and orange as juveniles and often develops red tips as it matures, so a colony of mothers and babies can look like two different mushrooms.

Tip: The Reef Farm rates this aquacultured line as very hardy and forgiving of higher nitrates (under ~50), but as a Ricordea yuma it still benefits from stable water quality. Place it low under low-to-moderate light with gentle flow.

Rainbow Yuma (Ultra Rainbow)representative

Rainbow Yuma (Ultra Rainbow)

UncommonIntermediate

The classic premium grade yuma displaying three, four or even five distinct colors across its body, mouth, inner rings, outer tentacles and skirt.

Tip: Place low in the tank under low-to-moderate light with gentle flow. As an intermediate Ricordea yuma it does best with stable parameters and detectable (rather than ultra-low) nitrate and phosphate, which help it stay plump and colorful.

Habitat & enclosure

Best in a **mature, stable reef tank, 10 gal (38 L) and up**. Yumas prefer cleaner water than nutrient-loving Discosoma but are not as fussy as SPS. Parameters: temperature **76-80 F (24-27 C)**, salinity **1.025 SG**, pH **8.1-8.4**, alkalinity **8-9.5 dKH**, calcium **420-440 ppm**, magnesium **~1300 ppm**, nitrate low (~2-10 ppm). Place mid-to-lower rockwork with good but not blasting light.

Substrate

Attaches to **live rock or frag plugs**. Seat fragments in a perforated container with rubble in gentle flow until the foot grips. Not a sand-dweller. Provide a stable, well-lit ledge once attached.

Equipment & setup

Moderate-to-strong reef lighting (**PAR ~75-150**) — higher than other mushrooms but below SPS levels. Low to moderate flow. Heater, quality salt, protein skimmer recommended for cleaner water, plus a spot-feeder for supplemental feeding.

Diet

**Photosynthetic** and also a willing feeder — gentle **spot-feeding** of small meaty foods or coral/amino foods 1-2x weekly improves color and growth. Yumas appreciate slightly more light energy than other mushrooms, so balanced lighting plus light feeding gives the best vesicle color.

Behavior & temperament

Peaceful with **no sweeper tentacles**; does not sting neighbors but should not be placed touching other corals. Slower to spread than Rhodactis/Discosoma, so it stays where you put it longer. Can detach if flow is too strong. Handle with gloves. A good 'next step' coral once a keeper has mastered easy mushrooms.

Health

Generally hardy but a bit more sensitive than common shrooms — sudden parameter swings, dirty water, or low light cause it to deflate, lose color, or detach. Pacific Ricordea (R. yuma) is widely regarded as slightly more delicate than Caribbean R. florida. Confine detached polyps in rubble to re-anchor; restore stable parameters and moderate light to recover color.

Tips, DIY & hacks

Frag by bisecting a polyp through the mouth with a sterile blade; each half heals into a new yuma. Because growth is slow, give cut pieces extra healing time in a low-flow rubble container. Provide a touch more light than for Discosoma to maintain the signature jeweled vesicles, but ramp light up gradually to avoid bleaching.
