Hello Erik,

I don't see any snout odontodes. The problem within this species group is that there are only patches of rather short odotodes.
What is the size of your specimen,
F. amazona can grow rather big.
For some
Farlowella spp. the males have a shorter snout and for others a shorter anal fin, but I don't know if any of these kriteria applies to the
amazona group as well.
Shortly: yes, I can tell. There are males or females

.
Within the
amazona group I have excluded
F. rugosa (due to its origin it is more than unlikely) and
F. platorynchus which has some medium abdominal plates and looks different. As
F. amazona has quite a lot of synonyms it is also possible that you have different variants of the same species (if we accept that all synonyms are justified).
F. henriquei is the forth described member of the
amazona group which seems to be also an option.
Cheers,
