Thanks. He's about 9" long. I was very lucky to get one his size; on the rare occasion that my lfs has flagtails, they are almost always in the 3-5" range (which would be kind of a pita for me, since I'd have to grow it out before putting it in the main tank at that size). Apparently this one was a trade in, along with another that was about an inch larger. The larger one had a had a bad eye and a scar on its mouth, so I got this one.
