Fish ID help

That is a fathead minnow, Pimephales promelas; it is the wild type from which the rosy red was derived. They're great active schooling fish and happily breed in tanks if provided with cave-like structures in which to lay eggs. The males develop three vertical black bands, swollen heads, and impressive bluish-white tubercles on the snout when in breeding condition and stake out nesting territories.

If you want to get it some companions, check out the local baitshop. Just be sure to quarantine the minnows for a good long while, as baitshop fish are often weak or diseased.
 
Thanks, good to know what it is now :) I don't plan on keeping it, I have someone who's going to pick them all up tomorrow for their pond. Although I am thinking about keeping at least one of the fancy goldfish (Oranda I think it's called) as I'm starting to really love this little guy. I've already named him "Rufus" lol
That is if he can be kept for awhile in a 20 gal tank by himself, if not I guess he will have to go to the big pond with the others :(
