Care at a glance

Species-specific aquarium care

  • Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 2.8 in / 7 cm).
  • Water: Freshwater.
  • Temperature: 73–79°F (range recorded for this species).
  • Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
  • Availability: Rarely or never seen in the aquarium trade; expect to source it from specialists or not at all.

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.

Species care notes

  • Tank: a base of at least 24 × 12 in (roughly 14 US gallons); space needed is rated “modest tank”.
  • Water: a fairly wide range, from slightly acidic to slightly alkaline, 79–86 °F, pH 6–7.5, 2–15 dGH.
  • Behaviour: temperament territorial.
  • Difficulty: Easy (Seriously Fish rating).

Short excerpts from the species profile:

  • Setup: “To appreciate it at its best, it really should be kept in a biotope setup, consisting of a sandy substrate over which is scattered lots of smooth pebbles and rocks of varying sizes.”
  • Diet: “Except when juvenile, these prefer a meaty diet.”
  • Tankmates: “In terms of temperament it's a decent match for many other fish, as it has a peaceful enough nature.”
  • Breeding: “Quite often bred in the hobby.”

Group care guide

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.

Sources 117119164118266

Health watch

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

Understanding the animal

This species is part of a group that hobbyists, aviculturists or zoos keep widely (Plecos), so it's included for completeness. It may be rare in captivity itself, or not kept at all. Use the group guide as a starting point and look for species-specific advice from experienced keepers.

OverviewThe zebra pleco (Hypancistrus zebra) is a species of freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armoured catfishes, and the subfamily Hypostominae, the suckermouth catfishes. This catfish is endemic to a small section of the Rio Xingu in Brazil. It occurs in the big bend area of the river, downstream from the town of Altamira, Para. It was first described in 1991. — Wikipedia (community-edited)
Where it livesHome ranges Population dynamics Growth parameters Max. ages / sizes Length-weight rel. Length-frequencies Mass conversion Recruitment Abundance Life cycle Reproduction Maturity Maturity/Gills rel. — FishBase
BehaviorSimilarly to other Hypancistrus species, the male will trap the female in a cave where she will lay her eggs for the male to fertilise. This is usually done at around a pH of 6.5-7.2 and a water tempurature of 27 °C. This process can take between 1 and 5 days depending on the experience the female has in motherhood. — Wikipedia (community-edited)
ReproductionEggs are deposited in caves. Male intensively tends the clutch. — FishBase
ConservationThe species is listed in Appendix II of the Convention on International Trade in Endangered Species (CITES) meaning that international trade (including in captive bred specimens) is regulated by the CITES permitting system. — Wikipedia (community-edited)
