Species-specific aquarium care

  • Tank: At least 78 in long and 39 in front to back for one adult (adults commonly reach about 19.7 in / 50 cm).
  • Water: Freshwater.
  • Temperature: 73–81°F (range recorded for this species).
  • pH: 6–8.
  • Hardness: 5–19 dGH.
  • Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
  • Diet: A grazer on plants and algae: base the diet on vegetable foods (algae wafers, blanched vegetables, spirulina). FishBase classes it as a herbivore.

Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.

Plecos (suckermouth catfish)

Applies to most species in this group. Habitat: South American rivers. Individual species can differ, so compare with the species numbers above and the linked sources.

Common aquarium bristlenoses are frequently unidentified Ancistrus stocks sold under “cirrhosus”. Verify identification before importing a common-bristlenose care sheet into the true A. cirrhosus record.

Housing & setup

  • Driftwood (some species rasp it for fiber), caves and good flow.
  • Common plecos reach 18–24 in; many smaller species stay under 6 in.

Diet

  • Algae wafers and vegetables for herbivores; meaty foods for carnivorous species.

Health watch

  • Starvation if they're expected to live on algae alone.

OverviewPterygoplichthys gibbiceps is a species of armored catfish native to Brazil, Ecuador, Peru and Venezuela, where it is found in the Orinoco and Amazon basins. Pterygoplichthys 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. Adult fish easily attain a length of 50 cm TL and can live for more than 20 years. A typical plec shape is shown. — Wikipedia (community-edited)
