    These fish are relatively slender, spiny Loricariids that lack an adipose fin. The caudal fin possesses long filamentous lobes on the upper and lower margins and is forked. The pectoral fin spines are extremely long. The entire dorsal surface of the head is covered in stout, sharp odontodes. The odontodes form a sharp keel on the lateral plates and, in juveniles, there are few to no odontodes on the plates above and below the keel rows. The cheek odontodes are fairly thin, but numerous. Males may have more and longer cheek odontodes and greatly elongated odontodes on the pectoral fin spine.

    A. adonis is an ornamental fish in the aquarium fishkeeping hobby. It is a generalist or opportunist feeder and will accept most kinds of fish food. Objects in the aquarium should be stable so that they are not knocked over by these fish. These fish are rather territorial and must be kept in a large aquarium with many refuges; care should be taken when keeping these fish with other loricariids as this has been known to result in death of one or both fish. They require well-filtered water. They have been bred in captivity.
