Grunt

Grunts don’t always get the spotlight, but they’re some of the most reliable, social, and eye-catching fish you can add to a saltwater tank. Their signature grunting sound, made by grinding their teeth, adds to their charm, and their schooling nature makes them an impressive sight in any setup. If you’re looking for a fish that thrives in groups and brings nonstop energy, grunts are a solid choice.

Spotlight on Saltwater Grunt Fish We Carry

French Grunt

The French Grunt (Haemulon flavolineatum) is a mix of bold yellow and silver, with sleek horizontal stripes that shimmer as it moves. These fish love to school, creating a striking display when kept in groups. Reaching up to 12 inches, they do best in spacious tanks with plenty of rock structures.

Bluestriped Grunt

Easily recognized by its electric blue stripes running across a golden-yellow body, the Bluestriped Grunt (Haemulon sciurus) is as flashy as it is active. Growing up to 14 inches, these fish are strong swimmers that prefer open water with spots to dart in and out of when needed.

Caring for Grunt Fish

  • Diet: Carnivores that enjoy fresh seafood—shrimp, squid, and small fish are all on the menu.
  • Tank Setup: These fish love room to move. Provide a large tank with open swimming areas and rock caves for resting.
  • Behavior: Social and best kept in groups—solitary grunts can be skittish but thrive in a small school.
