What Interesting Bottom Feeders Are There, Other Than Plecos and Cories?

There actually is a Blue Loach

But they get Big (10") and turn blue grey. Not the best for most tanks and not at all common to find. Many Loaches are endangered.

Those zebra danios were awesome looking, I think I've seen some at my LFS too. And that's kind kind of a bummer about the Rosy loaches. But I wouldn't want to out them in at too high a risk of life or limb.
