The Alien Blood Hammer Coral is a standout LPS coral with intense fluorescent colouration and the unmistakable hammer-shaped tentacles that make hammer corals such a popular feature in reef aquariums.
Under quality reef lighting, its contrasting colours can produce an incredible glow, making it an excellent choice for aquarists wanting a premium Euphyllia-style coral with serious visual impact.
Aquarium Care
Alien Blood Hammer Coral is best kept in a stable, established reef aquarium with consistent water parameters.
It prefers low to moderate water movement. The flow should be strong enough to gently move the fleshy polyps without blasting them directly or causing the tissue to remain tightly retracted.
Moderate reef lighting is generally ideal. When introducing the coral to stronger lighting, gradual acclimation is recommended.
Placement
Position the coral where its polyps have room to fully extend.
Hammer corals can develop long sweeper tentacles, particularly at night, and these can sting neighbouring corals. Leave adequate space between the Alien Blood Hammer and surrounding livestock to prevent coral warfare.
Avoid placing the fleshy tissue directly against rockwork, as repeated contact can cause damage.
Feeding
Hammer corals receive a significant portion of their energy through their symbiotic zooxanthellae, but occasional feeding can support growth and overall condition.
Suitable foods include:
Target feeding is optional but can be beneficial when done carefully.
Water Parameters
For best results, maintain stable reef conditions including:
-
Temperature: 24–26°C
-
Salinity: 1.024–1.026
-
Alkalinity: Approx. 7–9 dKH
-
Calcium: Approx. 400–450 ppm
-
Magnesium: Approx. 1250–1400 ppm
Consistency is more important than chasing exact numbers.
Why We Like Them
The Alien Blood Hammer Coral is all about colour, movement and presence.
Its fleshy hammer-shaped polyps sway naturally in the current, while the vivid fluorescent colouration makes it especially impressive under blue reef lighting.
For reef keepers wanting a premium LPS coral that can become a real focal point as it grows, this is an excellent choice.
