Family Pets had a Roseline a while back, but it was $32 and a good 5" long. I was in there this afternoon and they didn't have any otos at all. He did have some plecos though (chocolate, albino bristlenose, clown, and some others I didn't recognize).
Aaron (also the guy's name at Family Pets
) says his wholesale price sheet is faxed to them on Mondays so I'll give him a call and ask him to take a look for availability on the zebra otos as well as the roselines.
