The **Blue Devil** is an impressive, vibrant fish known for its striking appearance. These fish feature a predominantly deep blue body adorned with lighter markings. Young **Blue Devils** often display a mostly white body with blue facial spots, transitioning to a fully blue body as they mature.

Reaching up to 14 inches in length, the **Blue Devil** requires a minimum tank size of 125 gallons. These peaceful fish generally coexist well with other fish and coral, though they may prey on smaller fish and invertebrates. While suitable for reef tanks, caution is advised regarding smaller tank mates.

Due to their rarity and preference for deeper waters, **Blue Devils** are often expensive and require slightly cooler tank temperatures. A tank with ample live rock is crucial, providing shelter from intense lighting.

As carnivores, **Blue Devils** thrive on a diet rich in meaty foods. Initially, they may be finicky eaters, necessitating live foods like feeder shrimp. Once acclimated, they enjoy mysis and brine shrimp, along with high-quality frozen foods and fresh seafood such as fish, scallops, shrimp, and squid.
