There's one Apistogramma that carries its babies in its mouth, and it lives in a single river system in northeast Peru. This is that fish!
A devoted parent and a quiet showman, until another male shows up. Keep one male per tank and watch the whole story happen in front of you.
Care: Dwarf cichlid, and a rare biparental mouthbrooder. Soft, acidic water, pH 5.5 to 7, TDS 50 to 150, 70 to 78°F. Adult size about 2.5 inches. A 15 to 20 gallon tank with fine sand and caves. Eats flake, baby brine shrimp, and frozen bloodworms.
You're receiving a wild pair of fish.
