blue tang

A blue tang is a vibrant marine fish known for its striking bright blue coloration and oval shape. Native to coral reefs in the Indo-Pacific region, it plays a vital role in maintaining healthy reefs by eating algae that can otherwise overgrow corals. They are social, active fish that can often be seen swimming in schools. Blue tangs are also popular in the aquarium trade but require specific care due to their active nature and environmental needs. Their scientific name is *Paracanthurus hepatus*, and they are sometimes called "palette surgeonfish" because of their shape and coloration.
