I am planning to upgrade my betta to a 10 gallon and would like something for the bottom of the tank.
Otto's CAN be delicate but if you find them in you LFS, keep an eye on them for a week or so, if there still doing well at the shop then they've acclimated and should do equally well in your tank. There are many different dwarf loaches that come from the same home waters as Bettas so they would work equally well. Maybe a small shoal of Harleys as well.How about some nice black sand, a small piece of driftwood, some crypts and anubias along with 6 Otocinclus catfish.

I actually have did that with the 3 ottos i bought a while ago. I watched a large group for about a week or so then went to buy them and the LFS only had 3 left. But i still have them and they seem hardy IMO because they have been active since day 1 and are all still thriving even after switching to a different tank.
