அந்நிய மீனின் ஆக்கிரமிப்பால் அழிந்து வரும் நீர்நிலைகள்! | Tank cleaner fish tamil

The tank cleaner fish, also known as the suckermouth catfish or Pleco, is an invasive species originally from South America that has become a major ecological threat in India’s freshwater ecosystems.

These fish were introduced through the aquarium trade and have now spread to rivers, lakes, and wetlands, outcompeting native fish species for food and habitat.

They reproduce rapidly, are difficult to remove, and their presence threatens both biodiversity and the livelihoods of local communities who rely on native fish for food.

The tank cleaner fish is non-edible and unmarketable, yet dominates local fish catches, reducing the availability of native edible fish.

It is banned in India due to its invasive nature and harmful impact on native species and ecosystem.

The fish can survive in poor water conditions and spreads easily, making it hard to control once established.

Public awareness and strict regulations are needed to prevent further spread and protect India’s freshwater biodiversity.

This video will explore how the tank cleaner fish became invasive, its effects on Indian water bodies, and what can be done to manage this growing threat.
