Corals

Coral Profiles, Placement Guides, and Reef Care

Match each coral to usable light, water movement, feeding opportunity, and room to grow.

A coral placement succeeds when light and flow suit the animal without exposing nearby tissue to sweeper tentacles, shading, or abrasion. Use the profiles and guides to connect coral identity with water stability, feeding, aggression, and the space a colony will occupy after growth.
