Blue Line Grouper (Cephalopholis formosa)

Grouper fish are an interesting addition to an aquarium. They are a unique species of fish that have a variety of colors and patterns, and can be found in both fresh and saltwater environments. In an aquarium, they require plenty of space to swim and hide, as well as a well-maintained water quality. They are relatively peaceful and omnivorous, but can be aggressive when competing for space or food. Grouper fish are a great option for hobbyists looking for an active and attractive addition to their aquarium.
