Cottonwick Grunt (Haemulon melanurum)
The Caribbean Cottonwick Grunt is a classic and active addition to large saltwater aquariums. Known for its sleek silver body, subtle yellow highlights, and distinctive dark marking near the tail, this species brings constant movement and a true Caribbean reef feel to your tank.
Native to Caribbean reefs and sandy lagoon areas, Cottonwick Grunts appreciate plenty of open swimming space along with rockwork for shelter and security. They are generally peaceful and do best with other similarly sized tank mates, though they may become more assertive as they mature.
This species is hardy and adapts well to captivity, readily accepting a diet of meaty frozen foods such as mysis shrimp, brine shrimp, and chopped seafood.

Added a Cottonwick Grunt to my 120-gallon reef tank. It’s very active and adds a lot of movement. The fish has a beautiful silver body with yellow highlights and a dark tail mark. It’s peaceful with other fish and enjoys the frozen shrimp I feed it. Easy to care for and looks great in the tank.

The fish arrived healthy and has been swimming around the tank for a month. It’s active and curious, and the coloration is quite striking. I provide mysis shrimp daily and it eats well. A good addition to a larger reef setup.

This grunt is a highlight in my aquarium. The movement and appearance are impressive. It doesn’t stress other fish and seems to thrive in the open areas with some rock cover. Feeding is simple and it accepts frozen foods readily.
