Strawberry Grouper (Graysby Grouper – Cephalopholis cruentata)
The Caribbean Strawberry Grouper, also known as the Graysby Grouper, is a beautifully patterned predator that adds character and elegance to larger saltwater aquariums. Its reddish-brown body is dotted with subtle strawberry-like spots, giving it a unique and eye-catching appearance.
Native to Caribbean reefs, Graysby Groupers appreciate plenty of swimming space along with caves and rockwork to establish territory. While generally peaceful toward tankmates too large to eat, they are natural hunters and may prey on smaller fish, so careful tankmate selection is important.
This species is hardy and adapts well to captive life, readily accepting a diet of meaty frozen foods such as shrimp, fish, and squid.

The Strawberry Grouper is a stunning addition to my reef tank. Its colorful spots stand out beautifully against the background. It’s active and seems content in the tank with proper hiding spots. I feed it frozen shrimp weekly and it eats readily.
Colin Edmunds –
It’s a striking fish with a unique appearance. I placed it in a 120-gallon tank with rock formations and it’s settled well. It doesn’t attack larger fish, but I’ve had to remove a small tetra that was too small to survive.

The fish has become a focal point in my tank. It swims gracefully and shows no signs of stress. I’ve been feeding it frozen squid and shrimp, and it’s always active during feeding times.
