Description
The Cosmopolitan Rubyfish is a large, deep-water snapper known for its striking reddish-pink to purplish coloration and prominent eyes. This predatory species inhabits tropical and subtropical waters of the Indo-Pacific. Due to its substantial size and specialized deep-water requirements, it is exclusively suited for very large public aquariums and not for home setups.
