Species Overview
Black Crappie
The black crappie is a popular panfish found throughout North American lakes and reservoirs. Known for its delicate, sweet-tasting flesh, it is most actively caught during spring spawning when it moves to shallow water near cover.
Discus
The discus is often called the 'King of the Aquarium' for its disc-shaped body and stunning color patterns. Native to the Amazon floodplains, it requires warm, soft, acidic water and feeds its fry with a mucus secretion from its skin.
