Description and behavior

These fish burrow in the soft river bottoms and frequently occurs on sandy bottoms. These fish feed on mollusks, crustaceans, and organic debris.

They have rigid pectoral fin spines. The striped Raphael catfish also has tiny and curved protective spines running along its body. The striped Raphael catfish can grow up to 9½ inches (24 cm).

Juvenile raphael catfish have been recorded cleaning piscivorous fish such as Hoplias cf. malabaricus. The stripe pattern in the young may serve as a signal that allows for its recognition as a cleaner. It is noted that the striping pattern is not as strong in adults, and so the cleaning behavior is probably only seen in juveniles.

In the aquarium

These fish grow up to 9 to 12 cm
The striped Raphael catfish is a fine and sociable community fish that are peaceful to fellow catfishes and other fish species. However, they are nocturnal, and are usually not visible during the day.

It is best not to catch the striped Raphael catfish with a fish net because they are prone to sticking out their pectoral fin spines in a very rigid manner, especially if stressed. Untangling these spines from a net is difficult and dangerous to both handler and fish. Alternative methods should be used
Although known as a spawning fish, sexual differences are unknown and there have been no reports of being successfully bred in captivity. Because of this, these fish must be wild-caught, and therefore contaminants sometime occur in the hobby, such as Orinocodoras eigenmanni
