Description
The Yellowmask Surgeonfish is a large, active marine fish known for its striking blue-grey body, often adorned with fine horizontal lines, and a distinctive yellow mask around its eyes. It is a prolific algae grazer, making it beneficial for controlling nuisance algae in large reef or fish-only aquariums. Due to its potential size and territorial nature, it requires a spacious tank with plenty of swimming room and rockwork.
