Green Star Polyps Starter Care Guide
A practical introduction to green star polyps care, including health risks, water quality, tank setup, food and behaviour.

About the Green Star Polyps
Green star polyps form a purple mat covered in bright green waving polyps. They grow quickly in suitable conditions and can spread over rock, glass and equipment.
Aquarium-propagated frags are widely available. Their fast growth makes them satisfying to keep and difficult to remove once they reach the main rockwork.
Health risks to know about
Important concerns include ammonia or nitrite exposure, salinity shock, algae smothering, pests, copper exposure, excessive flow and tissue loss after unstable conditions.
A colony remaining closed, peeling away, losing colour or developing dead patches needs water testing and a check for pests, algae and nearby stinging coral.
Tank, water and equipment
Use a mature, cycled reef aquarium with stable rock, suitable reef lighting and moderate flow that keeps debris from settling without flattening the polyps.
Measure salinity with a calibrated refractometer. A specific gravity around 1.023 to 1.026 is a common coral range, with stable temperature and reef chemistry.
Food and feeding
Lighting supplies much of their nutrition, while the polyps can also capture tiny suspended foods.
Keep feeding modest so algae and detritus do not smother the mat.
Behaviour, tank mates and enrichment
Daily opening and closing with the light cycle is normal. A new frag may take time to open after transport.
Place green star polyps on an isolated rock if you want to control their spread. They can overgrow slower corals and are difficult to remove from porous rock.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
