Thanks for all the kind words, folks. We're shooting for the bottom of the stream look. I may add some coarse sand and I still want to fine tune the plants. Since I have a lot of xmas moss available I've decided I'm going to try to make a moss wall in the back. Oh! And I ordered a small blue LED moonlight on Ebay, so we'll see how that works.
Dramaqueen, my daughter's friend picked him out and named him and I think she did a good job. He's not as fancy as a lot of them I've seen here but I really like the color combination on him.
Kuklachica, I've seen him peering through a flowerpot hole as if it were a window. The loaches use the holes so I'd like to keep them but I think I'll just pile stones so he can't get to the holes but they still can, thanks.
FWIW - I was playing with my new camera's macro video function and made a little video of some of the loaches with a couple walk, er swim-on appearances by Manny. It looks best at the 480p setting. http://www.youtube.com/watch?v=NByl_y1upqM
