Dicas de identificação

1. 1

   Adipose Fin

   The most definitive feature for identifying Hasemania piatan (and the genus Hasemania) is the complete absence of an adipose fin, a small fleshy fin typically found between the dorsal and caudal fins in many other characins.

2. 2

   Lateral Stripe

   Observe the prominent dark lateral stripe running along the flank from the gill cover to the caudal peduncle. This stripe can vary in intensity but is consistently present.

3. 3

   Size and Body Shape

   Note the relatively small, slender, and elongated body shape, typical of many small tetra species.

4. 4

   Geographic Origin

   Confirmation of origin from the Piatan River basin in Brazil can aid in identification, especially when distinguishing from similar-looking species from other regions.
