Looks like it could be a surinamensis, altifrons or tapajos.
I think I'd lean towards the Tapajos just because of the darker dot. Where'd you get it and what did they call it?
There are no true surinamensis in trade. You wouldn’t likely randomly stumble across true surinamensis.
The surinamensis complex geos all have dark midlateral spots with the exception of altifrons who sometimes have a tiny or absent midlateral spot, so without also being able to see the bars, absense/presence of a cheek marking, and tail pattern, it’s nearly impossible to identify them at this size.
Grow the fish out more and repost it once the tail pattern and bars are showing.
