Isnt Gymnotus coatesi Nakedback knifefish?
-Tiger knifefish (Gymnotus tigre)
-Banded knifefish (Gymnotus carapo) ?
-Arapaima knifefish (Gymnotus arapaima) ?
-Zebra knifefish (Gymnotus pedanopterus)
all of which look pretty much the same
Never heard of that as a common name. However, you do see Gymnotus coatesi labeled as a Zebra Knife from time to time. Same as Carapo Knives. And each Knife listed may look the same, but some are just a little different.
Whether it's the color, patter, size, or temperament, etc.
-It is definitely
not a Tiger Knifefish (Gymnotus tigre); coloration is off as well as the shape of the fish.
-I'd rule-out Gymnotus pedanopterus as well, as the stripes are not solid enough, and the coloration is off as well.
Now this is where I get stumped, lol. Having a Gymnotus carapo myself, just based off his coloration I'm going to say that your Knife is not a Carapo;
however, the body shape and striping pattern are pretty close. >>Now, depending on where a Carapo was originally taken from, it can have a different coloration and pattern as opposed to one found in a different location in South America. I don't believe that there is too much on this, but I do remember reading an article on it about two years ago, so I guess I'll be looking for that, lol. Here are a few shots of my Carapo, just to compare:

So would I say that it can't be a Carapo? No, there is a possibility that it could be; I just don't know
for sure. Then again, I know very little about Gymnotus arapaima, and I'm not sure on their coloration. So that's another possibility... I'm still reading and learning, just to see what else I can find to help get a more confident ID, but that's the best I have for now, lol.
I need to make a Knifefish directory for myself to refer to or something... lol
