This species originates from the northern part of the Amazon basin and Guyana. They are a gentle peaceful species and do not burrow. When spawning they will become aggressive and territorial.

The male can be distinguished from the female because it is mottled with red-brown dots all over the body and worm-like markings on the head. The female is lighter in colour and has a shorter dorsal and anal fin. There can be a dark patch on her dorsal fin as well.

This species will pair off and choose their own mates. A strong bond will be established between compatible fish. This bond formation may involve a display of snapping, jaw-locking and other forms of belligerent behaviour.
