Care at a glance

Species-specific aquarium care

  • Tank: At least 72 in long and 36 in front to back for one adult (adults commonly reach about 17.7 in / 45 cm).
  • Water: Freshwater (tolerates brackish).
  • Temperature: 73–77°F (range recorded for this species).
  • Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
  • Diet: A predator: feed meaty foods sized to its mouth (frozen fish, shrimp, worms); it will eat tankmates that fit in its mouth. FishBase classes it as a carnivore.

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.

Care guide

Species care notes

  • Water: a fairly wide range, from slightly acidic to slightly alkaline, 73–77 °F, pH 6–7.5, 5–25 dGH.
  • Behaviour: temperament predatory.
  • Difficulty: Difficult (Seriously Fish rating).

Short excerpts from the species profile:

  • Setup: “It's a nocturnal species, so provide dim lighting and refuges in the form of big chunks of bogwood, tangles of beech branches, large rocks or lengths of plastic piping of a suitable bore.”
  • Diet: “Feeds on smaller fish, invertebrates and plant matter in nature, although thankfully there is no need to offer live ' feeder' fish in the aquarium.”
  • Tankmates: “Peaceful for its size and does well in a community of other placid, similarly-sized fish.”

Group care guide

Sun and imperial catfish

Applies to most species in this group. Habitat: The listed Indian catfish occupy Kerala rivers, from sluggish tributaries and backwaters used by Horabagrus brachysoma to the headwaters used by H. nigricollaris. [fg312-sun, fg312-imperial, fg312-ghats]. Individual species can differ, so compare with the species numbers above and the linked sources.

The water range applies to the two Horabagrus species only. H. brachysoma reaches about 45 cm standard length versus about 30 cm for H. nigricollaris; identify juveniles before buying. P. mitchelli is a roughly 15 cm omnivore with poorly documented captive requirements; the Western Ghats reference places it in Schilbeidae, so its assignment in the input needs taxonomic review. Its diet and temperature should not be inferred from Horabagrus. [fg312-sun, fg312-imperial, fg312-ghats]

Housing & setup

  • For one H. brachysoma, provide at least 180 × 60 × 60 cm (about 648 L); groups require larger quarters.
  • For H. nigricollaris, the published minimum is 120 × 45 × 45 cm (about 243 L).
  • Provide dim lighting and broad wood, rock or pipe refuges; secure heavy decorations against displacement.
  • Use efficient biological filtration for the large Horabagrus waste load; provide oxygenated flow for H. nigricollaris.
  • For Pseudeutropius mitchelli, retain open upper-water swimming space and well-aerated water rather than treating it as a bottom-dwelling Horabagrus.

Diet

  • Dried pellets for Horabagrus.

Social life

  • Horabagrus can live singly or in sufficiently spacious groups with placid fish too large to swallow; P. mitchelli is described as peaceful and upper-water dwelling. Do not put it with larger predatory Horabagrus.

Sources 1489149014911492

Health watch

  • Ammonia or nitrite injury in overloaded or immature systems.
  • External parasite and opportunistic bacterial infections: general captive-fish risks, not established family-specific prevalence.

What this means for care

  • Keep water within its wild range, 73–77 °F.
  • It tolerates or needs brackish water; check salinity needs before setup.
