The Blue Linckia is very intolerant of sudden changes in oxygen levels, salinity and pH of the water, and cannot tolerate copper-based medications. The drip-acclimation method is highly recommended due to their intolerance to changes in water chemistry. They should never be exposed to air while handling. In the wild, the Blue Linckia Sea Star is capable of regenerating a new starfish from almost any portion of its body that might break off. In the home aquarium, this is far less likely.
