So my best friend has a 75g at his Dad's house and he's breaking it down soon and the only fish left is a local stream catfish which looks like a juvenile Flathead, however it is well over 6-7 years old and a mere 6" so I figure it must be some type of Madtom or Stonecat, as I believe any Bullhead would be full-grown at 12-15" by 6 years (especially kept in a heated tank for tropicals). Also there is mottling that resembled a juvie Flathead so Bullheads are out of the question.
Any ideas what it could be, taken locally from a SE Pennsylvania trout stream?
