Good day to all farmers in the house.

I have been into the aquacultural industry for some time now with my major focus on hatching catfish claria breed.

Got some hybrid demand but it has been a difficult task for me in identifying and differentiating the hetrobranchus longifilis, hetro bidorsalis and a proper catfish hybrid (hetroclaria).

I would like to know the breed of the catfish in the photos attached below.

thanks.
