Crenicichla zebrina (Zebra pike cichlid) is a species of pike cichlid native to South America. It inhabits clear to moderately turbid streams and small rivers with moderate current, often among submerged rocks, roots, and leaf litter where it can shelter and ambush prey.

Behavior and temperament: C. zebrina is a predatory, territorial fish. Adults are solitary or found in loose pairs, defending small territories, especially during breeding. They are aggressive toward smaller fish and conspecifics when space is limited; juveniles show more schooling tendencies until they mature. They exhibit typical pike-cichlid body shape—elongated and laterally compressed—adapted for quick lunges.
Feeding: Carnivorous ambush predator. Diet in the wild includes small fish, aquatic insects, crustaceans, and other invertebrates. In an aquarium, they accept live and frozen foods such as small feeder fish, shrimp, silversides, bloodworms, and suitably sized pellets; varied protein-rich diet promotes condition and coloration.
Water quality and husbandry: Best kept in well-filtered aquaria with stable parameters. Preferred water temperature: 24–28°C (75–82°F). pH: neutral to slightly acidic, about 6.0–7.5. Water hardness: soft to moderately hard (0–12 dGH). Moderate current and good oxygenation mimic natural habitat. Regular water changes and low nitrate levels are important. Provide hiding places—rockwork, driftwood, and dense marginal planting—to reduce stress and allow territorial behavior. Tankmates should be similar-sized, robust species or kept singly/pairs to avoid aggression.
