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 2.2 in / 5.49 cm).
  • Water: Freshwater.
  • Temperature: 73–79°F (range recorded for this species).
  • pH: 6.5–7.8.
  • Hardness: 5–18 dGH.
  • Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.

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 24 × 12 in (roughly 14 US gallons); space needed is rated “modest tank”.
  • Water: soft, acidic water, 72–81 °F, pH 5–7, 0–5 dGH.
  • Behaviour: temperament species tank; in a pair; not a community fish.
  • Difficulty: Moderate (Seriously Fish rating).

Short excerpts from the species profile:

  • Setup: “Can be maintained in a fully-decorated aquarium although many breeders prefer not to use a substrate for ease of maintenance.”
  • Diet: “Likely to prey on insects and other small invertebrates/zooplankton in nature.”
  • Tankmates: “Not recommended for the standard community set-up for reasons already touched upon.”

Group care guide

Bettas (fighting fish)

Applies to most species in this group. Habitat: Shallow rice paddies and marshes. Individual species can differ, so compare with the species numbers above and the linked sources.

Housing & setup

  • A heated, filtered tank of at least 5 gallons, with gentle flow and plants.
  • Domestic B. splendens should generally be maintained alone. Other Betta species need their own compatibility plan; B. imbellis can be maintained as a pair with adequate cover.

Diet

  • Betta pellets plus frozen foods.

Sources 117119164118252253

Social life

  • Use species-specific social housing: B. splendens alone under the detailed Seriously Fish recommendation; B. imbellis may be housed as a compatible pair.

Sources 117119164118252253

Health watch

  • Fin rot in dirty water; never keep bettas in tiny unheated bowls.
