Rainbow Yuma Mushroom Colony
Ricordea Yuma mushrooms require low-to-moderate lighting (50–150 PAR) and low-flow, stable water conditions, ideally with lower, “dirtier” nutrient levels. They are hardy, photosynthetic, and best placed on the sandbed or lower rockwork. They can be fed occasionally with meaty foods but are prone to bleaching under high light.
Key Care Requirements
- Water Flow: Low to moderate, or “gentle” flow to prevent them from detaching.
- Placement: Bottom of the tank, on sandbed or in shaded, lower-rockwork areas.
- Water Quality: Stable, but Yumas often prefer slightly higher nitrate and phosphate levels than other corals.
- Feeding: Primarily photosynthetic, but benefit from spot-feeding meaty foods (mysis, brine shrimp) 1-2 times a week.

FAQ
What is the ideal lighting for Rainbow Yuma Mushroom Colony?
The ideal lighting range is 50–150 PAR, with low-to-moderate intensity. High light exposure can cause bleaching.
Where should I place the Rainbow Yuma Mushroom Colony in my tank?
Place them on the sandbed or in shaded, lower-rockwork areas to avoid strong light and water flow.
Do Rainbow Yuma Mushrooms need regular feeding?
They are primarily photosynthetic and do not require daily feeding. Spot-feeding with mysis or brine shrimp once or twice a week is beneficial.

Sebastian Murray –
Easy to maintain and grows well in my 10-gallon reef tank. I placed them on the sandbed with moderate lighting and gentle flow. They’ve been thriving for three months with only occasional feeding.
Emily King –
Grew quickly in my tank with low flow and stable water. I keep them in a shaded corner and feed them brine shrimp once a week. No issues so far, though I noticed some color fading under brighter lights.
Diana Hart –
Very hardy and resilient. I didn’t have to adjust water parameters much. They stayed healthy even during water changes. Only feed once a week and keep them in the lower section of the tank.
