Bushymouth Catfish
Ancistrus dolichopterus




Nocturnal with large suckermouth
You can recognise the bushymouth catfish by its large suckermouth. The fish uses this to cling to stones and roots. It likes to eat algae and it lives on the bottom of streams and rivers.
It can be hard to see. It often hides. It also likes to be awake at night. Can you find it?

The male takes care of the eggs
When the male become sexually mature he develops large antenna-like growths on his head.
The female lays large yellow eggs and fastens them in cracks in tree roots. The male guards the eggs and fans them until they hatch. Then the larvae have to survive by themselves.
