Care guide
Tenuis Acropora
Species guidance · AI-assisted · Model audited · Revision 2
Give settled colonies bright reef light and strong, changing flow through the branches. Acclimate new frags gradually, keep water chemistry steady, and check for pests or tissue loss.
This Acropora develops branching clusters with small corallites arranged around each branch tip. Several similar species make trade identifications uncertain.
Requirements
- Care level
- Advanced
- Temperament
- Allow room for expansion and competition
Placement and environment
- Lighting
- Bright light is generally appropriate after gradual acclimation; requirements vary substantially among species and colonies.
- Water flow
- Strong, changing circulation should reach around and through branches without a close, fixed jet.
- Placement
- Middle to upper rockwork after acclimation. Room between neighboring colonies. Open routes for water through branches.
- Habitat
- Upper reef slopes.
Feeding
- Feeding
- Photosynthetic; fine planktonic foods can supplement normal reef nutrition. Avoid sudden nutrient stripping or excessive feeding.
Acclimation and long-term care
- Warning signs
- Rapid or slow tissue loss after stress. Acropora-eating flatworms and other pests. Self-shading and reduced flow in growing colonies.
- Growth
- Branching colonies often form compact clusters. Leave space for growth and water movement around the branches.
