Help identify this knifefish

[Jaydenbasurto6]

On exotic fish shop there is a knife that is called carapo tiger knifefish, to me it looks like a macana tiger knifefish, what do you guys think

hI,there are two species: gymnotus carapo-banded knivefish., and gymnotus tigre- tiger knivefish. So,your name of this fish is nonsense...
Your fish could be : False Tiger Knifefish (Gymnotus javari) .

To me it looks like a false zebra knife, gymnotus javari
