RF EI Tiger 3cm Frag
Acropora is one of the most diverse and popular groups of SPS corals in the marine aquarium hobby, prized for its intricate branching, tabling, plating, and encrusting growth forms. Depending on the species and morph, colonies can display spectacular combinations of blue, purple, green, yellow, pink, red, orange, and gold.
Under strong reef lighting, many Acropora develop intense fluorescent colors and contrasting growth tips. With excellent water quality, strong flow, and stable parameters, they can form impressive mature colonies that provide exceptional structure and movement within an SPS reef.

The Tiger 3cm frag has grown well in my 120-gallon reef tank. After a few weeks of acclimation under strong lighting, it started showing vibrant blue and purple tips. The flow and lighting setup I have matches the recommended conditions, and the coral has become a focal point in the tank.

I’ve had this frag for about two months now. It’s been stable and shows good color development. I keep the lighting on for 8 hours daily and maintain strong flow. The growth is steady, though it’s still small and will take time to mature.

The coral looks stunning with its bright fluorescent colors. I followed the PAR range and placed it in the upper mid-zone. It’s been thriving and has not shown any signs of stress or bleaching.
