What kind of fish did I buy?

I went out today and bought 7 zebra danois, 2 platies, 1 mickey mouse platy, and 5 fish I don't know what they are.
These fish are a light orange, small, a black line at the end of their bodies just before their tail and as they get older they get a black line down the upper length of their bodies which when you look closer looks like dots linked together. I think they might be a kind of tetra and they seem a little aggressive to. They've been chasing my mickey mouse platy. Maybe they just don't like Walt Disney memorabilia.

Eurika!  I went on line and looked around and I found a pic of a Gold Barb that looks just like my little fish. So You guys put me onto the right track.
Thank You!
