Ive seen an earlier video version of your longifilis on youtube. I didnt know that was you

They are very rare so if it is (im not an expect) you are very lucky i have seen that particular bidorsalis in person and he was amazing.i have also seen a fully grown longifillis and that was identical to mine in every way a definite difference between the 2.keep osting vids and pics they are my favourite catfish.mine feeds on sprats trout prawns and his favourite food is worms he goes mad for them.your growth on yours looks good!
There is no doubt mine looks identical to the picture below your video. Funny thing is I wanted a bidorsalis, I guess dreams come true!
What do you feed yours?
I feed mine prawns, sword fish, worms, etc.
