A human-bred aquarium fish prized for its bright colour has escaped into a Philippines crater lake

Flowerhorn cichlids, bred by humans, have found their way into Lake Sampaloc, a crater lake in the Philippines. Their presence poses a significant threat to the local ecosystem, competing aggressively with native ayungin fish and disrupting aquaculture. Experts raise alarms about the potential for disease transmission and the rapid expansion of this invasive species, underscoring a pressing global issue of domesticated animals affecting natural habitats.
