Harlequin Shark Aquarium Care Guide

Keeping Harlequin Shark in an aquarium requires the right conditions.

Aquarium Information

• Care level: intermediate
• Temperament: semi-aggressive
• Diet: omnivore
• Minimum tank size: 50 gallons (for a single specimen, larger for groups or mixed tanks)
• Compatibility: Can be kept with other robust, similarly sized, and semi-aggressive fish. Avoid keeping with very small, timid, or long-finned species. Often territorial, especially towards conspecifics or fish with similar body shapes/colors.
• Special requirements: Requires a well-filtered tank with plenty of hiding places (caves, driftwood, dense planting) to establish territories. A strong current is appreciated. A tight-fitting lid is essential as they are known jumpers.
