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

Flowerhorn cichlids, a human-bred aquarium fish prized for bright colour, have entered Lake Sampaloc in the Philippines.

The invasive species threatens the local ecosystem by competing aggressively with native ayungin fish.

Experts warn of potential disease transmission and rapid expansion of the flowerhorn cichlid population.

The case highlights a global issue of domesticated animals disrupting natural habitats.
