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 4.8 in / 12.2 cm).
  • Water: Freshwater.
  • Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
  • 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.

Care guide

Species care notes

  • Tank: a base of at least 47 × 12 in (roughly 29 US gallons); space needed is rated “large tank”.
  • Water: soft, acidic water, 68–79 °F, pH 6–7, 1–10 dGH.
  • Behaviour: temperament territorial; in a pair; not a community fish.
  • Difficulty: Moderate (Seriously Fish rating).

Short excerpts from the species profile:

  • Setup: “The most essential item of décor is a soft, sandy substrate so that the fish can browse naturally (see 'Diet').”
  • Diet: “Likely a generalised omnivore in nature.”
  • Tankmates: “Males are territorial, particularly when spawning, while very small tankmates may be predated upon.”
  • Breeding: “Biparental substrate spawner.”

Group care guide

Oscars, peacock bass, pike cichlids and eartheaters

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

This guide includes warm-water predators and subtropical eartheaters. Gymnogeophagus balzanii needs its own seasonal water-temperature schedule; do not apply the predator temperature default.

Housing & setup

  • For one adult Astronotus ocellatus, plan at least a 150 × 60 cm base according to Seriously Fish; pairs and groups need more space. Use separate adult plans for Cichla and each eartheater species.
  • Soft sand for eartheaters (Geophagus, Satanoperca), which sift substrate through their gills.

Climate & lighting

Starting point only: The blanket warm-water interval excludes the subtropical seasonal requirements of G. balzanii; use overrides. Check the species-specific values for this animal where shown.

Water77–84°F

Diet

  • Astronotus ocellatus is an omnivore with a preference for animal foods; offer quality pellets and varied suitable foods rather than feeder-fish dependence. Cichla and substrate-sifting eartheaters require separate feeding plans.

Sources 117119164259269

Health watch

  • Hole-in-the-head disease and lateral line erosion in poor water; eartheaters suffer on sharp gravel.

Understanding the animal

This species is part of a group that hobbyists, aviculturists or zoos keep widely (Cichlids), 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.
