Description

The Congo puffer (Tetraodon miurus) is a freshwater pufferfish of the family Tetraodontidae from the Congo basin in Central Africa. The species has a stocky body with the eyes high on the head and an upward-pointing mouth, and reaches about 15 cm. The colour is highly variable, from red and orange to brown, providing camouflage. It is an ambush predator that buries itself in sand or gravel with only the eyes visible and lunges suddenly at passing prey. Like other puffers it can inflate and its tissue contains the potent poison tetrodotoxin. In the aquarium it is solitary and aggressive toward conspecifics.
