Description
The Pearl Blenny (*Istiblennius edentulus*) is a hardy saltwater fish recognized by its mottled brown and tan body adorned with small white spots, offering excellent camouflage. Primarily an herbivore, it actively grazes on algae, making it a valuable addition to mature reef or fish-only aquariums. While generally peaceful, it can exhibit territorial behavior towards other blennies or similar bottom-dwelling species.
