Ricordea Yuma vs Florida Comparison: Care and Coloration
Ricordea mushrooms are the gateway drug to corallimorph collecting, but the two commonly sold species demand surprisingly different care regimes despite looking superficially similar on a shop frag tile. A careful ricordea yuma vs florida comparison shows that getting Yuma colouration right is harder than the price tag suggests, and Florida’s apparent simplicity hides a preference for specific flow profiles. This guide from Gensou Aquascaping at 5 Everton Park explains the practical differences so you can pick the species that matches your lighting, feeding habits and budget. Singapore frag pricing and supply chain notes are included.
Taxonomic Basics
Both are corallimorphs, not true mushrooms in the Discosoma sense. Ricordea florida comes from the Caribbean, primarily Florida Keys, Cuba, Haiti and occasionally Puerto Rico. Ricordea yuma originates from the Indo-Pacific, with most imports via Indonesia. The two species share the distinctive circular vesicle-covered disc but differ in vesicle size, pattern density and colour range. Yuma displays larger vesicles and a wider pigment palette; Florida shows smaller, more densely packed vesicles.
Appearance and Colour Range
Florida ricordea trends toward solid or two-tone discs in orange, green, blue, yellow or purple. Named morphs like Rainbow Florida, Sunkist Florida and Fluorescent Green are stable across propagation. Yuma shows more chromatic complexity with multi-colour bullseye patterns, including green-red-orange concentric circles, purple-yellow contrasts and metallic sheens. The visual complexity of Yumas drives their premium pricing, with standout morphs trading at $150-400 SGD per polyp.
Lighting Requirements
Florida ricordea thrives at moderate PAR of 80-150, placed on rockwork or upper sand bed. Colour intensifies under blue-heavy reef spectrum without demanding the tight PAR windows that Yumas tolerate. Yumas require stricter lighting control; most display best at PAR 60-100 with heavy blue spectrum. Excess intensity bleaches Yuma pigmentation within weeks, and insufficient light causes the polyp to deflate and lose vesicle definition.

Flow Tolerance Differences
Florida ricordea tolerates moderate flow comfortably and displays best under gentle pulsing currents that gently move the disc without folding it. Yumas prefer lower, more laminar flow and fold or drop polyps under strong wavemaker output. A shaded corner with indirect flow from a single powerhead suits Yumas better than open reef placement. Tank flow zoning matters more with Yumas than with almost any other common coral.
Feeding Response
Both species are photosynthetic but respond dramatically to targeted feeding. Offer small pieces of mysis, cyclops or coral pellet once or twice weekly. Yumas show the stronger feeding response, capturing food and holding it in disc contraction for 30-60 minutes. Florida ricordea accepts food but often rejects larger pieces, preferring smaller particulate. Feeding accelerates growth and reproduction through pedal laceration in both species.
Water Parameter Tolerance
Florida ricordea accepts wider nutrient ranges, thriving at nitrate 5-25 ppm and phosphate 0.05-0.2 ppm. It tolerates higher organic load, which makes it suitable for mid-tier reef tanks still dialling in chemistry. Yumas prefer tighter parameter control at nitrate 5-15 ppm and phosphate 0.05-0.1 ppm. Both species demand stable alkalinity at 7.5-9 dKH; swings of 2 dKH over 24 hours cause visible tissue stress in Yumas. The calcium alkalinity stability reef guide covers stability practices that protect sensitive corallimorphs.
Placement and Growth Habits
Florida ricordea attaches readily to rock or frag plugs and spreads by pedal laceration into clusters within 6-12 months. Place on mid-to-upper rockwork for best colour. Yumas attach more slowly and occasionally refuse to adhere to smooth frag plugs; rough epoxy or live rock rubble works better. Yumas also prefer shaded pockets and caves rather than open display positions. Our aquascape soft coral garden reef piece covers layouts that showcase both species.
Propagation and Spread Rate
Florida ricordea propagates aggressively through pedal laceration, producing satellite polyps every few weeks under good conditions. A single polyp becomes a 10-polyp cluster within a year. Yumas reproduce more slowly, typically one or two new polyps per parent per year. This slower spread is part of why Yuma pricing stays high; supply is genuinely limited beyond import cycles. Manual fragging using a razor blade through the base accelerates propagation for both species.
Sourcing and Pricing in Singapore
Florida ricordea is imported sporadically from Caribbean suppliers via US transshippers, with $40-90 SGD typical for a standard orange or green polyp. Named morphs command $100-250. Yuma availability depends on Indonesian export quotas; Pasir Ris shops stock individual polyps at $80-180 for common colours and $250-450 for showpiece multi-colour morphs. The supply chain for both species is volatile, with seasonal gaps of two to three months common.
Choosing Between the Two
Pick Florida ricordea if you want fast-spreading colour, tolerance for imperfect chemistry and lower initial investment. Pick Yuma if you want collectible showpiece polyps, can control lighting and flow precisely and accept slower propagation. Many reef keepers run both in separate zones of the same tank, using Florida for bulk colour across open rockwork and Yumas for feature placements in shaded pockets.
Handling and Propagation Safety
Corallimorphs contain palytoxin at far lower concentrations than true zoanthids, but handling still warrants basic precautions: nitrile gloves, eye protection and avoiding cuts during fragging. Flush tools and frag plugs in fresh saltwater and work in ventilated spaces. The how to frag soft corals beginners guide covers the full safety workflow for home propagation.
