Genus - TSN, yes. Species - perhaps a Pseudoplatystoma corruscans, albeit it should have only spots, no lines, but maybe the pattern has not finished evolving.

That's why I figured it wasn't TSN but maybe some sort of tigrinnus hybrid because of the lines. I've never seen a TSN that had such red on it though, the red is why I thought it might be a RTC hybrid, it must not be a normal TSN, I've seen adult TSN a few times, never had such color

Don't get me wrong, mate, please. Just sharing my thoughts and trying to help. Anyone is free to disagree.

This is no hybrid at all and no need to even invoke hybrids here IMHO. There are no known/confirmed tigrinus hybrids.

There are (debatably) 9 currently recognized species of TSNs: 4 in one revision, 8 in the other, plus 1 more in a separate paper. I doubt you have seen all 9 of them in adult and sub-adult ages. They are hard to ID until the pattern finishes developing; then they clearly differ in appearance... plus there are some regional variations or subspecies not split-off or not ID'ed yet by taxonomists. That's all. There is no deep enigma here IMHO. http://www.monsterfishkeepers.com/forums/showthread.php?322161-TSN-ID-Chart-Pseudoplatystoma

There is no such thing per se as "normal TSN" because it is not a single species of fish but a genus. It is like saying the fish does not look like the normal 9 known TSNs do.
