Xenia is the only coral that exhibit a rhythmic pulsing of their tentacles. This creates a beautiful and fascinating movement in the tank.
Some people find Xenia difficult to keep and others find that it grows alarmingly fast and can become somewhat of a weed in the tank.
Xenia like moderate to bright lighting and moderate to fairly strong water flow.
Many think that iodine additions are essential to their growth, but we have never found that to be true and these are all grown with no iodine supplementation in the tanks that they are kept in.
Xenia primarily spreads by the stems making contact with a surface which it adheres to and starts a new area of growth. In this fashion, they can inch their way across most surfaces including the glass of the aquarium. They can be quite attractive if they form a pulsating wall on the back or side of the tank walls.
Because they can grow and spread fairly rapidly under good conditions, their growth should be monitored and occasional pruning may be required to keep them under control. The pruning is easily done if the coral is growing on the glass
Feeding is not required. It is believed that they absorb nutrients from the water.
