Care

Gray Triggerfish require a spacious tank with plenty of room to swim and structures to explore. They are known to be somewhat aggressive, particularly towards smaller tank mates or those with similar body shapes. It's important to provide a varied diet, including meaty foods like shrimp, squid, and fish.

Reproduction

In the wild, Gray Triggerfish exhibit fascinating nesting behaviors, with females guarding their nests aggressively. While breeding them in captivity is challenging, understanding their natural reproductive habits can be rewarding for advanced hobbyists.

Habitat

These fish are found in subtropical and tropical waters, often around reefs and rocky areas where they can forage for crustaceans and mollusks. They are adept at flipping over rocks and using their strong jaws to access food.
