Overview

  • The Firemouth Cichlid (Thorichthys meeki) is a Central American cichlid known for its bright red-orange throat, which it flares to display.

  • Grows to about 5 in (12 cm) standard length.
  • Almost all fish in the trade are commercially raised.

Habitat

  • A tank with a base of 48 × 12 in (120 × 30 cm).
  • Soft sand, smooth rocks, driftwood and caves.
  • Water: 68–90°F (20–32°C), pH 6.5–8.5, GH 2–15.

Fish Care

  • Hardy and adaptable.
  • Sand lets it feed naturally.

Compatibility

  • Can live with similar-sized Central American cichlids if each has room for a territory.

Aquarium Behavior

  • Flares its gill covers to threaten rivals.

Breeding
