What breed?

Hello! I don’t know if this is the right place but a while back I purchased some neon tetras and the person bagging them accidentally included this guy. Anybody know what he is? (He’s the fish in the front)

Looks like a green fire tetra (Aphyocharax Rathbuni)

@Rocky998 nailed it. Nice litttle fish fish species, sometimes a little nippy.

If the ID is correct this is a fish that needs a group of at least 6.

This fish should not be kept with slow moving fish as they will bite fins.

I've kept them, and they are beauties. The first time I bought a group they brought Ich in for the first time in many years, but I cured it and added to the group, and they were lively fish.
The reputation as nippers is the result of us doing things wrong. Ideally, they should be in groups, but how you keep those groups matters. If the water in your tank moves around with a good current, they'll thrive. In slow tanks, they get bored.
A lot of bright silvery social fish have sunlight and ripples as camouflage, and very active lifestyles that can twist into nipping if they are bored, or if the tank set up doesn't let them burn off energy in fast water.
With accidental arrivals, you can stuck. There's only so much space. If you can easily fit more and don't have fancy guppies, Bettas or other 'freak-fin" fish, I would do it. They are great in groups. But there should be surface current, and a large enough tanks (30 gallon plus) for them to frolic.

thank you guys for all the information! He’s currently in a 30 gallon tank with a some other tetras and a few guppies. I’ve never seen him bother any of the other fish, he’s always just stuck to the other tetras and was too busy eating off the glass lol.
I wouldn’t mind getting some more as I have enough room but if I do I’m worried the rest will start nipping.

Fancy guppy tails are serious temptation for a lot of feisty little tetras....

It's a peacock. I've never kept them, but my sources tell me that they aren't aquatic and it will drown if you keep it under water too long.
