Aquacultured Horn Coral - Hydnophora grandis

This Hydnophora Coral has been grown in an aquaculture facility and has not been harvested from a wild reef.

Horn Coral (Hydnophora sp.) is similar to Acropora but lacks the individual polyp formations. It is instead covered in fleshy tissue which is typically brown or intense fluorescent green. The branches can resemble thick tree branches or the coral can be found in a more encrusting/plating formation.

Hydnophora rely heavily on their zooxanthallae algae for food and need high light to preserve color and provide energy. They should not be placed close to other corals as they may sting nearby competitors.
