Description
The Bluetail Boxfish is a visually stunning marine fish characterized by its vibrant blue body, often topped with yellow or gold, and a distinctive blue tail covered in black spots. These slow-moving fish have a rigid, box-like body and can release a potent toxin (ostracitoxin) when stressed, which is harmful to other tank inhabitants. They require a large, well-established aquarium with excellent water quality.
