The peco's teeth are definately fish eating ones. They are conical and sharp, but not bladed along the edges. This means when a fish is bitten it cannot escape. This kind of teeth are very bad for tearing apart large prey, or biting off chunks.

And the peco's throut could not eat things like that pelican because its throat and mouth are not big enough.
