I don't know much about many types of catfish, but my guess is some kind of marble bumblebee cat? Possibly? Not sure but that hopefully gets you in some kind of direction!
Your fish matches the northern:
Adipose appears separate from caudal.
Light spots in front of dorsal
Strong midcaudal crescentic bar
Black saddle on adipose fin does not reach edge
Brindled:
adipose not separate from caudal (yours appears separate: better pic would help)
tip of dorsal fin black (notice yours is definitely white)
black saddle on adipose fin reaches edge (yours doesn't)
