damselfish \ chromis help

[Kryptic4L]

Hello,

I was at the store's today and found some nice fish, they were listed as ruby chromis. However I am unsure what their actual name was as I would like to look up info on them. google came up unsuccessful.

As discription of how I would remeber them would be

Reddish tone with a stripe going from the top of the head diagonally towards the midsection of the body ending about half way down.

Anyone know what i might be talking about.
