Did You Know These Fin-tastic Warmouth Facts?

Warmouth facts about the warmouth fish species.

Warmouth (Lepomis gulosus) are a fish belonging to the sunfish family. They have many common names, but, like rock bass and shadow bass, they are mostly known as goggle-eye fishes. Adult warmouths are generally omnivores, but a warmouth’s diet is mainly carnivorous as they feed on small fishes and insects. Warmouths can be easily confused with rock bass, but warmouths have six anal fins, which are one physical characteristic that is different from the rock bass. Warmouths have a mouth that is two times larger as compared to other sunfishes. This allows them to prey on large fishes.

Adult warmouths prefer habitats in deeper waters, and all other warmouths along with their nests move deeper in the ocean as the temperature rises. They tend to habitat in turbid, muddy water where there is ample vegetation and dense cover.
