Blue Spotted Grouper (Argus)

About this fish

Blue Spotted Grouper (Argus) (Cephalopholis argus) is a predatory reef fish for experienced hobbyists keeping a larger home saltwater aquarium. As a feeder fish and active hunter, it’s best used as a showpiece predator rather than a community “reef-safe” fish. With strong feeding habits and a tendency to eat small tankmates that fit in its mouth, it’s a practical choice for fish-only (or predator-style) setups where you can control tank size, rockwork, and compatible companions.

Features:

• Predatory temperament: it will eat any fish or crustacean small enough to swallow
• Needs a big tank and plenty of rock for hiding and security
• Does well as a centerpiece predator in fish-only/predator-style aquarium layouts
• Feedings can include meaty frozen foods such as silversides, squid, and shrimp
• Best kept with large, robust tankmates that are not suitable prey
• Arrives as live livestock and should be acclimated slowly for reduced stress
• Provide a quiet settling spot so the fish can adapt after arrival
