Size 500mm or 19.7" SL. Find near, nearer or same sized spp.
Identification The genus Panaque is identified by the teeth, which are spoon-shaped. This means that the teeth are noticeably wider at the tip than at the base. Other loricariidae have teeth that are similar width all the way from one end to the other. A second distinguishing feature is the lack of a buccal papilla, which is a "flap of skin" on the inside of the mouth. See pictures in this PDF on Pterygoplichthys.

This species has a dull (not red or orange) eye and a basic olive colouration that greys with age and, irrespective of age, black longitudinal stripes. Young fish show a white ring around the caudal peduncle, a windowed or clear caudal fin and white tips to the fins.
Sexing Undocumented, although with most ancistrine plecos the genital papilla of the female is round and blunt, that of the male by comparison is smaller and pointed. It is not known at what size this method of sexing can be used on Royal Plecos. It is possible that heavy odontal growth is associated with males. .
General Remarks It is thought by some that this species most closely matches the description of the Blue Eyed Pleco, Panaque suttonorum. In adulthood, it is grey with dark grey spots and dashes. In youth, especially, it shows the white caudal peduncle ring. It's likely a close relative unless the Maracaibo species is proven to be surprisingly widespread.

Feeding All Panaque appear to feed on wood, so wood should be present in the tank. They also take prepared algae wafers and fresh vegetables (zucchini, cucumber, peas, green beans) and tubers (potato, yams and similar).
Furniture Natural habitat is among fallen trees and wood-tangles.
Compatibility Generally peaceful, but may defend their territory against conspecifics.
Suggested Tankmates Most community fish, this fish is very secretive and so you will want more active fish around to provide something to watch. Larger specimens will work nearly all but the most ferocious and agressive fish. Smaller specimens should not be kept with large predators, for obvious reasons.
Breeding Unreported.
Breeding Reports There is no breeding report.
