3" in diameter, WYSIWYG and fully conditioned by WWC! Plate Corals have their feeding tentacles out most of the time, so feeding them can be relatively easy. The trick with feeding them is to hold a piece of meaty food in place with a pair of tweezers until the Plate Coral grabs a hold of the food with their tentacles. In regards to placement and flow, place them on the sand where they can receive lower intensity light (around 125 or less par) and in an area of low to low-medium flow.Lighting = Low Light at around 75 to 125 parFlow = Low to Medium Alternating FlowFeeding = Good Quality Frozen LPS Food 1x / weekly
