I agree with Byron. In your original statement you made it sound like there would be one or two pieces of wood and the rest open sandy bottom. That would not be a healthy environment for loaches IMO.
What Byron and I were trying to get at is that they need a LOT of structures/hiding places on the bottom because that is what they evolved for and that is what they expect. I know some substrate fishes have a greatly reduced swim bladder because they just don't use it (for neutral buoyancy); they don't swim in the water column long enough for it to be useful.
So if you were to stuff the bottom with driftwood and rocks and caves and then have a thick canopy cover I think it would be a fine tank.
