Description
The Blackback Butterflyfish is a striking marine fish native to the Red Sea, characterized by its yellow body with dark vertical stripes and a prominent black posterior. It is a specialized feeder, primarily consuming coral polyps in the wild, making it challenging to keep in a typical reef aquarium. This species requires an advanced aquarist who can provide a large, mature tank and a varied diet.
