Neon Green Trumpet Coral (Caulastrea furcata) is a hardy, beginner-friendly LPS (Large Polyp Stony) coral that adds a vibrant pop of color to any reef tank. Here’s a care guide to keep it thriving:
Lighting: Moderate (PAR 80-150). Can tolerate lower or higher lighting but does best with moderate intensity. Too much light may cause bleaching.
Flow: Low to moderate. Too much flow can cause the fleshy polyps to retract and stress the coral.
Placement: Place in the middle to lower sections of the tank, away from strong direct flow.
Water Parameters:
Feeding: While it gets energy from photosynthesis via its zooxanthellae, feeding meaty foods like mysis shrimp or reef roids 1-2 times a week can promote faster growth.
Aggression: Mildly aggressive. It has short sweeper tentacles, so provide some space (at least a few inches) from other corals to prevent stinging.
Growth & Propagation: Forms branching colonies that can be fragged easily by cutting at the base of a branch.
For optimal placement of your Neon Green Trumpet Coral, consider the following factors based on your tank’s layout:
Mid to Lower Region: This coral prefers moderate lighting, so placing it on a stable rock ledge or the sandy bottom works well. If your tank has strong lighting (like LEDs at high intensity), start lower and gradually move it up if needed.
Moderate Flow Area: Avoid direct flow from powerheads, as excessive water movement can cause the fleshy polyps to retract. A gentle, swaying motion in the water is ideal.
Space From Other Corals: Keep at least 3-4 inches of space around it to prevent accidental stinging from its sweeper tentacles.
