A 250 gallon or larger aquarium is required due to the size and feeding habits of this fish. It is extremely aggressive and may eat its tank mates as well as crustaceans.

The Blue Dot Grouper prefers a diet of meaty foods such as krill, shrimp, and other small fish.

Customer Testimonials

Paul Pigott Santa Barbara , CA
Amazingly beautiful fish, and by far the fastest fish I have in my tank. Changes color depending on situation - usually a beautiful black to orange covered in brilliant blue dots. Aggressive eater, but kind to all other fish.
