Care guide
Blastomussa
Group guidance · AI-assisted · Model audited · Revision 3
Start in subdued light with gentle, indirect flow and steady water chemistry. Give the polyps room to inflate away from sharp rock and strong stingers. Offer small meaty foods.
Requirements
- Care level
- Beginner
- Temperament
- Allow room for expansion and competition
Placement and environment
- Lighting
- Subdued lighting is a good starting point; excessive intensity can cause poor expansion or abnormal inflation.
- Water flow
- Gentle to moderate indirect movement should keep the colony clean without holding the polyps closed.
- Placement
- Lower or shaded rockwork. Space for fully inflated polyps. Away from stronger stinging neighbors.
Feeding
- Feeding
- Photosynthetic; regular small portions of finely chopped meaty foods can support long-term condition.
Acclimation and long-term care
- Warning signs
- Poor response to excessive lighting. Damage from nearby aggressive corals. Overfeeding or food theft by fish and invertebrates.
