Care guide
Hammer coral
Group guidance · AI-assisted · Model audited · Revision 2
Start hammers in low to moderate light and indirect flow that lets the polyps sway. Allow room for expansion and keep torches separate. Take extra care when handling wall forms.
Requirements
- Care level
- Intermediate
- Temperament
- Allow generous clearance from neighboring livestock
Placement and environment
- Lighting
- Low to moderate light often works well; increase exposure slowly after a move.
- Water flow
- Aim for a gentle, changing sway with no persistent pressure against the skeleton.
- Placement
- Lower to middle rockwork. Room for expanded polyps and sweepers. Stable mounting without pressure on living tissue.
Feeding
- Feeding
- Photosynthetic; small supplemental meaty foods or coral pellets can support growth when the coral accepts them.
Acclimation and long-term care
- Warning signs
- Wall forms can be less forgiving than branching forms. Tissue recession or brown jelly-like material. Injury from handling, falls, or direct pump flow.
