Blastomussa Coral Care Guide
Blastomussa wellsi is a large-polyp stony coral with fleshy corallites, valued in reef aquaria for its bright colours and tolerance of lower light.
Overview
Blastomussa wellsi is a large-polyp stony (LPS) coral described by Wijsman-Best in 1973. A colony consists of a small group of corallites, each with its own fleshy polyp. The corallites measure 9-14 mm in diameter and are brightly coloured — dark red, green, grey or blue — often with contrasting oral discs.
Taxonomy
- Family: Mussidae
- Genus: Blastomussa
- Scientific name: Blastomussa wellsi
- Common names: blastomussa, blasto
Habitat
The species is found in the west and central Indo-Pacific region. It is described as an uncommon reef coral whose mature colonies are thought to be declining.
Tank requirements
- Minimum tank volume: 80 L
- Temperature: 24-27 °C (75-81 °F)
- pH: 8.1-8.4
- Salinity: SG 1.024-1.026
- Carbonate hardness: 8-12 dKH
- Lighting: low to moderate
- Water flow: low
Diet
Blastomussa wellsi contains symbiotic zooxanthellae for photosynthesis and supplements this by capturing zooplankton with its tentacles and absorbing dissolved organic matter. In aquaria it thrives primarily on light, with occasional target feeding.
Reef compatibility
The coral is peaceful and well suited to shaded, lower-flow areas of the reef. Its minimal sweeper tentacles make it a forgiving neighbour for other corals.
Conservation status
IUCN Red List: Near Threatened. The probable decline is attributed to habitat destruction and collection for the aquarium trade.
