What kind of tetra is this

[Callisto405]

Got this by mistake in a bag of fish. Can't figure what species it is. It's the fish with the black stripes and red tail

the bigger fish on the left is a serape tetra (fin nipper) and the smaller fish at the back is a flame tetra (nice fish). get rid of the serpae and get a few more flames

Serpae tetra on left not so good. Flame tetra on right lovely little guy. They all have teeth some use them some don't.

Yeh they should get a separate tank for the fires and serapes
