Interesting to see, and despite lacking their pectoral lobes, it looks very healthy.
The unfortunate case with P. senegalus is that nowadays, many of the cheaper captive bred specimens are the result of some degree of inbreeding. Breeding them another generation into that will have malformarions like this. I remember when the first Channa torsaensis came into the hobby (Cobalt Blues back then), I kept a group of fry which were second generation captive bred. First bred in Germany, then their offspring bred again in Wales and I had the fry of those. As they grew, at least three of them had some shocking deformities, mostly to the mouth though.
My only advice to this which hasn't already been said, is to keep it in shallower water and with no hiding spaces (except for surface cover like floating plants). As it grows, it will really struggle to get out of hiding spaces and will also not have much control when surfacing to breathe.
Happy fish-keeping!
