Hypothesis about the over population of Janitor Fish

So, when you hear stories about how they are taking over Marikina River and Laguna de Bay and how hard it is to get rid of them, well, just think how that janitor fish survived. The janitor fish multiply so fast that, combined with their amazing ability for survival, and you have people complaining about how they are fast infesting our lakes. In a forum called Scientist Solutions, someone described the scenario this way: “If you throw a fishing net in one of our affected lakes, you can get a boatful (dinghy size) in about 5 minutes.”
Despite the assurance of that Auburn University fish curator that the janitor fish is edible, they have not found their way into our cuisine. However, some enterprising people have found some good use for them — as biofuel, the fish bones as water purifier, and fish skin as accent for footwear. The lowly janitor fish comes of age.


Hypothesis:

Among these invasive species in the "Pterygoplochthys pardalis found in marikina and Pterygoplochthys disjunctivus found in laguna de Bay.
