I get this fish lot often very territorial and requires plenty of hiding places. This whole process of hiding and flashing out in the open is so much fun to watch. Azure Damselfish will eat everything thrown in the tank from pellets, flakes, brine shrimps to frozen food. Fish has the capability to bully other similar size fish so, keeping semi-aggressive fish is advisable.
This is another pretty Chrysiptera one should eye, for their tank. Azure Damselfish is easy to keep and easy to care. It is not very demanding on the systems. So, if you are more interested in knowing more in detail about Azure click link Animal-World and FishBase.
