The body shape of the Del looks WC to me but the head doesn't as much. Maybe it's just been underfed, which is common in LFS, so it hasn't had a chance to develop a belly.
The Teug, hard to tell.
Others are better at this than I am. A lot of CB polys get a "beer gut" appearance - they don't stay uniformly streamlined as they grow. The heads look different as well, I see that sometimes they look more round / sloped / convex on the head, sometimes there are froggy looking eyes, though I find all that harder to distinguish on the Teugelsi. The CB Dels can have some really cool patterns.

has a wild caught Teug. I would say the majority of the rest of us who have them are CB. You can look for differences in this thread.

Keep posting pictures! I think the straight side shots are the most helpful personally.
How big are the Del / Teug?
I'll try to find photos of WC vs CB Delhezi for you too.
