Knifefish ID confirmation

[bottles]

Hey all,
I bought this as a tiger. At first I thought that they were zebras, but now I'm unsure. They were only 3" so I got a pretty good deal on a tiger, or paid a little too much for a zebra. Either way, they are very nice fish and I'm happy with the purchase, but I just want a positive ID. I can't get a picture from the top, they are always hiding and only come out for a second before they're gone. It looks like they are getting some markings on top of the head, but it's hard to tell. The person that I purchased these from is very knowledgeable, and he says that they are definitely tigers. He's brought in tigers, zebras and other rare knifefish in the past.
If I can't get a positive ID, I'll just sit back and wait for them to get bigger. Either way, I'm looking forward to seeing how these guys turn out.
Thanks

Looks like a carapo to me (think that's how it's spelled)

 

[bottles]

Thanks, Kev. I don't think it's carapo. Carapo usually have a bit of a deeper body, but it'll be easier to tell once they get a bit more size.

 

[bottles]

Gymnotus Coatesi maybe?.... I think I might have to wait until they get some more size on them.

 

[bottles]

Any other ideas? I'm not ruling out carapo yet because they are so small; I am leaning towards zebra though, gymnotus pedanopterus.

Tough call, seems to fit the bill of a bit off all of the above species in some respects. Time should give more clues maybe.

Ya, I don't like playing the waiting game, but I might not have a choice.

 

[kevinfleming21]

Haha, well you already bought him right?

 

[bottles]

Haha that's true, but if they're zebras I'd go and pick up some more since I've kept them in groups in the past. If they're tigers, then I won't bother, since I hear they don't tolerate each other.

True, well good luck man.
