Aussie Mermaid Branching Hammer

About this coral

Aussie Mermaid Branching Hammer is an LPS coral in the Euphyllia (hammer coral) group. Branching Euphyllia are commonly kept as reef centerpiece corals and are valued for their fleshy tentacles and overall “hammer” look. In an aquarium, they’re typically placed where their polyps can extend and where water movement is enough to keep feeding particles in reach, but not so strong that tissue is stressed.

Features:

• Group-level Euphyllia care generally starts with moderate light and medium flow for good tentacle expansion
• Use stable, mature reef conditions so the coral can settle comfortably after placement
• Give it physical space from aggressive neighbors, since Euphyllia are LPS and can be affected by direct contact
• In many setups, periodic meaty foods and/or capturing suspended foods helps support health (follow your shop’s feeding guidance)
• Target placement on the rockwork can improve polyp visibility and reduce bumping during tank maintenance
• If water movement or lighting is changed, acclimate gradually to help prevent retraction stress
