Species Overview
Brook Trout
The brook trout is actually a char, native to cold, clean streams of eastern North America. Its olive-green body with distinctive worm-like markings (vermiculations) and red spots with blue halos make it one of the most beautiful freshwater fish.
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.
