📍 Central America
The Vieja maculicauda, commonly known as the Blackbelt Cichlid, is a large and striking Central American cichlid recognized by the distinctive black vertical band across its midsection and vibrant red-orange coloration on its belly. It is a robust and personable fish that can become quite interactive with its keeper over time. Due to its size and territorial nature, it requires a spacious aquarium with careful tank mate selection.

Care Guide
Diet
Vieja maculicauda is an omnivore that thrives on a varied diet including high-quality large cichlid pellets, spirulina-based foods, and blanched vegetables such as zucchini and spinach. Supplement with protein sources like earthworms, shrimp, and occasional feeder insects. Feed adults once or twice daily, offering only what they can consume in a few minutes to maintain water quality.
Behavior
The Blackbelt Cichlid is a bold, active fish that patrols its territory with confidence and can become aggressive, especially during breeding periods. It is known to dig substrate and rearrange decorations, so a sturdy aquascape is recommended. While it can be kept with similarly sized robust fish, it will not tolerate smaller or more docile tank mates and may bully them relentlessly.
Breeding
Vieja maculicauda is an open substrate spawner that forms monogamous pairs and exhibits strong parental care over eggs and fry. Breeding is triggered by slightly warmer water, flat rock surfaces, and a nutritious diet; the female can lay several hundred eggs at a time. Both parents aggressively defend the spawn, so a dedicated breeding tank or very large community setup is advisable.
