Pterygoplichthys is everywhere

And its official now. Both Pterygoplichthys disjunctivus and P. pardalis are found down here.

To add to the misery, 3 species of Oreochromis, Amphilophus trimaculatum and Hemichromis bimaculatus.

Although Pterygopichthys seems to have caused some river bank erosion issues in the US and there is some speculation they might cause changes in the aquatic vegetation, they seem a lesser problem worldwide than the four horsemen of the aquatic biodiversity apocalypse: Tilapia, Gambusia, Goldfish, and Trout.

I suspect the list should read Tilapia, Gambusia, Koi Carp (also Silver,Grass etc) and Trout.. Koi Carp are definitely more harmful though Goldfish more likely to be introduced but there is little fear of Black moors and their kin establishing feral populations.

I guess the Loricariid should fit in with these four replace the Trout in tropical countries. I am sure they exist all over India, not only in Chennai.

Poor fish .... much maligned and people BBQ'ing them.
How any of you can even THINK about eating a catfish is beyond my comprehension.
Eating a fish to me is like eating my pet dog or cat ...

Are these Pterygoplichthys??? Collected locally last weekend. Unfortunately, I was collecting and couldn't take any pictures. Does the abdominal pattern show up only in adult specimens???

Yes, I think they are but with the caution I've not seen them that small before.

They look like the Pterygoplichthys juveniles I caught in Singapore.
