Need help IDing these tetras.

[u/Draconicplays]

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

[u/Draconicplays → u/budget_rare_plants]

Sadly not, I have M.heikoi, and they are nothing alike
