Chalice Coral – Green Convict – Medium
The Green Convict Chalice Coral (Oxypora glabra) is a striking LPS coral featuring rich green colouration, textured growth and contrasting corallites that give the colony plenty of detail under reef lighting.
As it becomes established, this Chalice develops a thin encrusting to plating growth form, gradually spreading across the surrounding rockwork and creating an impressive layered feature within the aquarium.

Aquarium Placement
Green Convict Chalice generally performs best in the lower to middle regions of the reef, where it receives lower-to-moderate lighting.
Provide moderate indirect flow to prevent detritus from collecting across the colony without constantly blasting the fleshy tissue.
Allow plenty of surrounding rockwork for the coral to gradually encrust and plate outward as it grows.
Green Convict Colouration
The Green Convict variety brings strong green colouration and textured patterning to the reef, with its raised corallites creating additional contrast across the colony.
Under blue-spectrum reef lighting, the fluorescent tones can become particularly noticeable.
Feeding
Although primarily photosynthetic, Chalice Corals can benefit from occasional supplemental feeding.
Suitable foods include:
- Mysis shrimp
- Fine LPS coral foods
- Small meaty coral preparations
- Dedicated coral pellets
- Fine planktonic foods
Occasional feeding can help support healthy tissue, colour and continued growth.
Give It Some Space
Chalice Corals can extend feeding or sweeper tentacles beyond the visible edge of the colony and may sting neighbouring corals.
Allow several centimetres of clearance and additional room for the colony to spread as it matures.
Stable Reef Parameters
For best results, maintain stable:
- Calcium
- Alkalinity
- Magnesium
- Salinity
- Temperature
- Nitrate and phosphate
Stable water chemistry combined with appropriate lighting and flow will help maintain healthy tissue and strong colour.
With its bold green colour, textured surface and attractive plating growth, the Medium Green Convict Chalice Coral makes an excellent feature piece for an established reef aquarium.
Colour, pattern, shape and exact colony size may vary between individual specimens.
