Could be mistaken but I do think IMO yours has the round eyes of b.b or b.y assuming that we are still happy that the eye shape is a defining trait.
Would suggest that some Bagarius seem flakey however found mine to be quite resilient to changes in temperature although was never in more than 76 degrees and it didn’t fluctuate wildly. What mine was susceptible to was lack of oxygen in the water and a pump failure claimed him after getting him from 7” to 20” in 18 months.
I would say to keep him at the temperature he’s at as he seems ok with that and personally lean towards it being bagarius bagarius like mine. You cant over oxygenate that tank so an extra air pump would be a must for me.
