A thin, plating chalice coral with small corallites and toothed ridges, often green, brown or grey with brighter edges. Naming: chalice corals were in Pectiniidae; current classifications place Oxypora in Lobophylliidae. Placement: bottom to middle, set horizontally so the plate spreads. Light and flow: low to moderate light and medium flow. Water: Keep calcium around 400–450 ppm, alkalinity at dKH 8–12 and magnesium around 1250–1350 ppm, and keep them steady; regular dosing of calcium, alkalinity and trace elements (or a calcium reactor in a busy reef) is needed as the coral grows. Growth: slow; chalice corals encrust or form plates. LiveAquaria does not list this species; the care figures are from its green chalice coral page (Echinophyllia aspera), a close relative. Selling: this is a CITES Appendix II coral. Frags grown in the UK can be sold freely; wild-collected or imported pieces must have been legally imported with CITES paperwork.

Diet
Mainly photosynthetic. Chalices feed at night and benefit from small meaty foods or filter-feeder foods.
Breeding
Frag by cutting the plate with a saw into pieces with some tissue intact, then glue flat.
Compatibility and tank mates
Semi-aggressive: it can put out sweeper tentacles that harm nearby corals. Give it about 10 cm.
