Colu Posted March 23 Share Posted March 23 (edited) Looks like a species of Astyanax if you no the exact location were you were it shouldn't be difficult to narrow it down Edited March 23 by Colu Stupid autocorrect 4 Link to comment Share on other sites More sharing options...
Marcelo Posted March 23 Author Share Posted March 23 (edited) Hi Colu, I have the exact location … it was in city of “Alto Paraíso de Goias” state of Goias and country Brazil 😐 but many thanks for mentioning this name … I will try to google it … Maybe this one https://en.wikipedia.org/wiki/Astyanax_argyrimarginatus so basically they are like Tetras ?! Haha Edited March 23 by Marcelo 2 Link to comment Share on other sites More sharing options...
Marcelo Posted March 23 Author Share Posted March 23 (edited) I forgot to mention: they bite 😬 not that they will take a slice of you and not like our fish tank “kissing” our fingers … something in between - very cool .. I was swimming and they were all there looking at me like a big insect 🫤 Edited March 23 by Marcelo 3 Link to comment Share on other sites More sharing options...
Biotope Biologist Posted March 23 Share Posted March 23 (edited) Looks like Astyanax paranae as Colu mentioned. This is a species that occupies rio de paraña which is east of where you were located It also looks like there are some 2 spot mixed in there? Im looking at fishbase to see if these species overlap in your region. It looks like bifasciatus overlaps Edited March 23 by Biotope Biologist 5 1 Link to comment Share on other sites More sharing options...
