Biologists from the Ateneo de Manila University confirmed the presence of tinfoil barb or Barbonymus schwanefeldii in Laguna de Bay, which they said "poses a threat to native fish by outcompeting them for food and breeding sites." | via ANC 24/7
⚠️ Why It Can Be Invasive
Fast growth and large size: Can outcompete native fish for food and space.
Omnivorous diet: Eats a wide variety of foods, potentially impacting aquatic ecosystems.
Long lifespan and hardy: Survives in many environments, especially in warm climates.
Human release: Often introduced through aquarium dumping or religious release (e.g., "mercy releases").
✅ Responsible Fishkeeping
If you keep tinfoil barbs:
Never release them into the wild.
Work with local fish clubs or aquariums if rehoming is needed.
Follow regional laws — some areas may restrict or regulate their sale and ownership.
