Ventralis Featherfin Cichlid (Ophthalmotilapia ventralis)
The Ventralis Featherfin Cichlid is a stunning and unique species native to the deep, rocky waters of Lake Tanganyika in East Africa. Males are especially eye-catching with their elongated, feather-like ventral fins and shimmering blue, yellow, or metallic coloration, depending on the regional variant. This cichlid is peaceful for a Tanganyikan species and is best kept in species tanks or with other compatible Tanganyika natives.
Their graceful swimming and elaborate fins make them a standout display fish for experienced aquarists.
