Is this a butleri or not?

I'd say its definitely a T. sirtalis. but could be anything from sirtalis sirtalis to sirtalis fitchi. It looks similar to specimens I've seen of T.s. pickeringii,fitchi, and parietalis.

in the third picture you can see the characteristic red lines/spots inbetween the scales just above the lateral lines.
