Green Pavona Live Aquacultured SPS Coral
Information
Pavona are commonly referred to as Cactus Corals as several of their growth forms resemble cacti. They are a fast growing SPS Coral and can quickly form a large colony from a single frag. They are considered one of the easiest SPS corals to care for.
Lighting
Pavona do best in Medium lighting. Pavona generally do not change color as much as other SPS corals, and do not really benefit from higher lighting than they need. Lights that are too bright tend to bleach the coral. If you already have strong lighting, it may require a longer acclimation period to intense lighting such as metal halides and higher wattage LED's.
Water Flow
Strong water movement is recommended. This is for two reasons, first it both carries food to the colony better and keeps detritus from building on the colony. When detritus settles on the coral, it can die back and unfortunately the different growth forms all can fall victim to dead flow areas. The second reason is aesthetically it looks nice to see the tentacles blow around. One of the major criticisms of SPS dominant aquariums is a lack of movement in the corals themselves. You kind of have to find movement when you can, so in the more furry examples of Pavona, a good strong current can produce a nice aesthetic.
Feeding
Pavona relies heavily on the products of their zooxanthellae but also may feed on rotifers and similarly sized microfauna in the water column. Placing a Pavona colony does require a bit of forethought because this type of stony coral has sweeper tentacles that can damage nearby corals.
