They thrive in the typical water condition as most corals, Yumas like low light, low flow and should be photo-acclimated appon arrival to the new system. Florida Ricordea can handle and thrive under mod-mod/high flow, high lighting. Keep your main parameters within range and you should be fine......Some feed them I have never had luck with Florida ricordea eating anything, Yumas will readily accept small meaty fare if offered. Feeding will increase reproduction and health of yumas.
