Pterygoplichthys gibbiceps is a species of freshwater fish of the genus Pterygoplichthys of the family Loricariidae of order Siluriformes. This species is found throughout river basins in the Amazon region of South America.
P. gibbiceps shows all the characteristic features of its genus—a large dorsal fin with more than nine rays, prominent nasal flares and a prominent hump or crest anterior to the dorsal fin as well as a substantial base to the dorsal fin. 
A typical plec shape is shown, patternation consists of primarily irregular largish brown spots on a yellowish backgroung giving a honeycombed like appearance, additional pattern features common to related species may be visible on close inspection. As this fish grows the spots get smaller.
Like most plecs this species is primarily vegetarian though will eat dead animals.
In the wild these fish are found in shoals in sluggish rivers of the Amazon and Orinoco river systems, they also occupy flooded land during the wet season. During the dry season P. gibbiceps will aestivate in burrows around 1 metre long dug into mud banks along the length of a river, egg rearing is also presumed to take place in burrow.
The species name comes from the Latin gibbus—hump and Greek cep—head, a reference to the centrally located ridge. Common names include 'gibbys', leopard sailfin catfish and clown plecs—the juveniles have a comical appearance due to the large and obvious spots.
Ancistrus gibbiceps and Glyptoperichthys gibbiceps are synonyms of P. gibbiceps.
This fish is extremely popular in the aquarium, due to its unusual appearance and its ability to eat algae; the bane of all aquarists. This and other related species are bred in ponds in tropical regions for the aquarium trade. In general P. gibbiceps is peaceful towards other fish though territorial disputes arise with other plecos. Though not nocturnal they are more active at night and will spend daylight hours 'hiding' in a secluded location. Wood appears to be an essential part of this species diet—possibly as a digestive aid rather than for any nutritional value. As the fish grows big (up to 40 cm in the aquarium) a large tank with good filtration is required, in general these fish are tolerant to a wide range of freshwater conditions though prefer well aerated water.


在野生自然水域中是群居鱼,性温和,即使对较小的鱼只也和平对待。建议饲养在大型的混养缸中。
食性:在晚上喂食,可吃藻类、锭状饲料、风化土砾等。较大的鱼(30cm长)每天需要6至8粒的锭状饲料或大量的藻类。如果都没有食物可吃,最后也会啃食煮过的莴苣。
注意事项:因为它分泌的排泄物多,所以需要强劲、大台的过滤器。假使水族箱过小,它会变得顽抗而难以驾驭
