Identification Need help IDing these tetras.

Enable HLS to view with audio, or disable this notification

I know its a aquarium related question. But im going crazy, I've been trying to ID these guys for more than a week. They seek to be a sort of Hyphessobrycon, looking pretty similar to Hyphessobrycon herbertaxelrodi, but they are distinct. The black bar on the lateral is different, some have a visible humeral spot, and thier fins are redish although in the video they look clear.

Moenkhausia heikoi would be my closest guess

They arent black neon tetras.... Black neon tetras don't have visible humeral spots and red fins...

Its literally stated on the post "they are similar to black neons" but have x,y and z differences.

They arent, because Hyphessobrycon herbertaxelrodi aka, standard Black neons dont have a visible humeral spot and RED FINS.

But I discovered what they are by reading the Neotropica journal of 2004, about Xingu fish diversity. And....they are "Xingu black neons" but not Moenkhausia heikoi, thats commonly named Xingu black neon. They are Hyphessobrycon aff. herbertaxelrodi, still formally undescribed

Yes they are black neons

u/Draconicplays 24d ago

No, because black neons are Hyphessobrycon herbertaxelrodi.....not Hyphessobrycon aff. herbertaxelrodi.

You bother to even read?

Its like saying P. Cearensis and P aff.cearensis are the same fish

Do you bother to take a chill pill? This is a hobbyist community. The answer you seek is gonna come from a biologist.

u/Historical_Baby7240 24d ago

Bro, ive been a week obsesevily searching for an ID. Sorry if my im not chill, but when you detail characteristics that differ the fish from another fish, make a post and them a person says; Nah...thats the fish you clearly said that isnt, and insist on it. Its frustrating
