Yes, the above fish is a fire pike. Note the huge, dark tear under the eye and Hadrian is correct about the red dots on the side.
The fish you are referring to Taz is the Atabapo version of lugubris. In fact, it should be called Cr. sp. cf. lugubris "Atabapo".
Since the fire pike appears to be it's own, unique, unammed species, Cr. sp. "Atabapo" fits it better.
