I have never bought a fish at Wal-Mart until today. I happened to peek in the tanks to see a fish which I couldn't remember the name of at the time. It is a species I have always wanted, but had never seen until now. It must have been a stowaway in one of the shipments. I picked it up for a buck fifty (payed for an Otocinclus). When I got home I looked it up, and it's a Banded Characidium, also known as a Banded Darter. It is now at home in my 29 gal. and seems to be adjusting well.
