Ricordea Mushroom Coral Care: Yuma vs Florida Species
Ricordea mushrooms bridge the gap between beginner-friendly shrooms and high-end collector pieces, offering vivid colours that hold up under photography and reasonable growth rates that reward patience. This ricordea mushroom coral care guide from Gensou Aquascaping at 5 Everton Park compares the two species Singapore hobbyists actually buy — Ricordea florida and R. yuma — and covers the practical husbandry differences that matter. They are not interchangeable; Yuma and Florida have noticeably different demands and market values.
Quick Facts
- Two species: Ricordea florida (Caribbean) and R. yuma (Indo-Pacific)
- Florida tolerates lower light and beginner conditions better; cheaper per polyp
- Yuma requires moderate-high light, steadier parameters, and higher nutrient tolerance
- Yuma polyps are larger (5-10cm) than Florida (2-4cm) and usually more colourful
- Florida: $30-80 SGD per polyp; Yuma: $100-500+ per polyp for coloured specimens
- Both appreciate occasional target feeding with mysis or reef roids
- Ricordeas split naturally and will populate a rock over time
Identifying the Two Species
Florida ricordea have small, bumpy polyps with a regular texture across the oral disc and short, rounded tentacles. They grow in carpeting colonies on Caribbean rock. Colours include orange, green, blue, and occasional purples, with most wild specimens landing in green or orange.
Yuma ricordea are larger, with more distinct vesicle protrusions and often a frilled or ridged edge around the oral disc. Colours are intense — electric greens, deep reds, lavenders, and multi-colour specimens with banded disc patterns. A mature Yuma polyp can be the size of a dinner plate saucer.
Lighting Requirements
Florida ricordea thrive at modest lighting, 50-120 PAR at placement. They sit comfortably in lower sections of a tank under standard reef LED at 50-70% intensity. Excessive blue bleaches greens over time; a balanced white-blue spectrum preserves colour best.
Yuma need more light, 100-200 PAR at placement, and respond to spectrum shifts dramatically. Higher blue intensity enhances red and purple Yumas, while neutral spectrum favours green and orange strains. Match lighting to the specific specimen; a multi-colour Yuma bought under one shop’s light may shift within weeks under yours.
Flow Preferences
Both species prefer gentle to moderate flow. Strong laminar current causes the oral disc to fold and prevents feeding response. Indirect flow from a nearby powerhead or pulsed wavemaker set to low intensity works best.
Position them where they receive mild water movement but not constant blasting. A Yuma in direct flow from a Gyre pump will shrink and eventually detach within weeks.
Placement and Attachment
Ricordeas attach by pedal disc to rock. Newly fragged pieces sit on a frag plug or rubble rock and take one to three weeks to attach. Use a plastic mesh or specimen cup to protect them from being blown around during acclimation. Once attached, they remain stationary.
Floridas often carpet adjacent rock over months, producing dozens of daughter polyps. Yumas split more slowly but reach larger individual size.
Water Parameters
Florida ricordea accept a wide parameter range: salinity 1.024-1.026, temperature 24-27°C, nitrate 1-20 ppm, phosphate 0.02-0.1 ppm. They tolerate beginner-level nutrient swings better than most corals.
Yuma prefer tighter parameters: salinity 1.025-1.026, temperature 24-26°C, stable alkalinity 8-9 dKH. Rapid parameter swings cause Yumas to deflate or detach. A well-maintained reef controller reading stable for a month should precede adding a premium Yuma.
Feeding
Both species are photosynthetic but respond positively to target feeding once or twice a week. Offer small pieces of mysis, reef roids paste, or a few drops of liquid coral food directly onto the oral disc with a pipette. The mouth closes and draws the food in over several minutes.
Over-feeding is a real risk; feeding daily pollutes water and causes polyp swelling beyond healthy. Weekly feeding is optimal.
Colour Retention
Ricordea colour is driven by zooxanthellae density, anemone pigments, and symbiont species. Under suboptimal lighting or extreme ULNS, both species lose saturation. Maintain steady nutrient levels (nitrate 2-8, phosphate 0.03-0.06) and keep lighting constant for colour to stabilise. Expect six to eight weeks of settling before a new piece shows its final colour expression in your tank.
Pricing in Singapore
Florida ricordeas are common and cheap: $25-50 SGD per polyp for green and orange, $50-100 for blue or multi-colour. Rocks with 10-20 polyps sell at $150-300 depending on colour mix.
Yuma pricing varies enormously. A plain green Yuma runs $80-150 SGD per polyp. A multi-colour “rainbow” Yuma can reach $300-800 per polyp, and show-grade specimens with vivid red, orange, and blue in one disc can exceed $1000. Iwarna Aquafarm and Reef Depot get periodic Yuma shipments from Indonesia; premium specimens sell within days of arrival.
Fragging
Both species frag reliably. Use a sharp scalpel on a flat surface; cut the polyp radially through the mouth. Each half regenerates into a full polyp over weeks in low flow and moderate light. Place frags on dedicated frag plugs and keep them in a low-traffic zone for 2-3 weeks before repositioning.
Common Issues
A ricordea that repeatedly detaches and drifts is either flow-stressed, light-stressed, or being nipped by tankmates (wrasses, some angels). Move to a quieter location. A deflating ricordea usually indicates parameter swings; check alkalinity stability first.
