It tends to be quite peaceable for a damselfish, with young and adolescent individuals rarely causing problems in captivity. However, as it grows larger, it may become more pugnacious, especially toward small, more passive tankmates. Chrysiptera starcki is likely to chastise some of its less aggressive congeners.
It was once rarely available and thus very expensive, but with more collecting efforts in the Coral Sea, the price has come down.
