For more than 30 years, the residents of Sitio Tubigan, a small community in Barangay Banilad, Mandaue City, have relied on ornamental fish breeding as their primary source of income. Most of the families in Sitio Tubigan maintain fish pens where they breed and raise various species, primarily koi, guppy, and goldfish. These fish are fed and cared for daily, with work often beginning at dawn. After feeding and sorting, the residents either deliver their fish to aquarium shops and pet stores in downtown Cebu City or sell them directly to buyers who come to the area.
