This species has a thin body with a forked tailfin, silver coloration and five yellow, horizontal lines on its sides. Smallmouth grunts can grow to be up to 9 inches, but typically only grow to be around 6.5 inches.  

Smallmouth grunts spend a lot of time in schools, particularly during the day. At night, they feed on their prey, which includes plankton, small crustaceans and mollusks.  

There are various species of grunt fish, which are named for the sound they produce when grinding their teeth together. Smallmouth grunts have the smallest mouths of all grunt fish species.
