Fenestratus Cichlid (Vieja fenestratus)

Fenestratus Cichlid — Vieja fenestrata

Windowed pattern with Central American power

The Fenestratus Cichlid is a bold, heavy-bodied Central American species known for its dramatic “windowed” patterning. A bronze to olive base is layered with dark, broken barring and iridescent blue-green highlights that shimmer under strong lighting. Mature males often develop enhanced coloration along the face and fins, sometimes showing subtle orange or red accents depending on mood and dominance.

Native to river systems of Mexico and Guatemala, Vieja fenestrata is a confident midwater cruiser that establishes territory with posture and display. While assertive, it is generally manageable when given proper space. In large aquariums, this species becomes a commanding focal point without constant chaos.

Growing to 12–14+ inches, the Fenestratus is a substantial cichlid suited for experienced keepers with appropriately sized setups.
