Description
The Blackmargin Damsel is a hardy and attractive marine fish characterized by its greyish-blue body, yellow caudal fin, and a prominent black spot behind the gill plate. While generally robust, it can be territorial and semi-aggressive, especially towards conspecifics or smaller, more docile tankmates.
