Variola is a genus of marine fish known for the Coral Grouper and Marine Betta, popular in the reef aquarium trade. These fish are appreciated for their striking coloration and patterns. They are predatory and require a diet of meaty foods such as shrimp and fish. Care should be taken to only house them with larger fish that they cannot eat.
