STRIPED RAPHAEL CATFISH (Platydoras armatulus)

The Striped Raphael Catfish is a medium to large sized catfish that is very active. Being nocturnal, the Striped Raphael Catfish comes out mostly at night, though they are known for getting adjusted to daylight. They are native to the northern amazon rivers, and have not been known for breeding in the home aquarium.

 Their tough skin lets the Striped Raphael Catfish tolerate a variety of peaceful, and agressive fish, including some cichlids. Be careful whenever handling them. They have serrated fins that "pinch" whenever they are stressed. They must be handled with either glass or a plastic cup, because their serrated fins get caught up on the net, making it difficult for them to release themselves after.

They are also known as the "Talking Catfish" because while feeding they make a croaking sound. Whenever holding them, you can feel the vibration of the hum they are creating.
