Help ID barb

I know it is a barb not sure what kind? Another question will fish that should be kept in groups be alright for a couple days without others?

Looks like it might be a red tailed tin foil (I'm assuming it's a juvie). Is there a chance you might get a better picture?

That's kinda what I was thinking but the body shape threw me off a bit. I have had tinfoil barbs before never got one that small though.
