It has the double spot of C. kraussii, but I've never seen juvies before ...
There are only three species so if it’s a caquetaia, it’s likely a kraussi. Looks a little off though. Can you take better pics?

It does have the mid body blotch, and the blotch in the upper half of the caudal which would indicate krausii, (if truly caquetaia) but (maybe at a larger size) the blotch on the shoulder which is also a kraussi indicator isn't shown.

The other pic you provide has none of those indicators, but it may just be stressed, and the lack of substrate may cause it to wash out .
A better clearer side, and less angled view would help
