Species Overview
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.
雲紋犬牙石首魚
The spotted seatrout, despite its name, is a member of the drum family, not the trout family. It inhabits grass flats and estuaries along the Atlantic and Gulf coasts. Males produce a distinctive drumming sound to attract females.
