Kinetic, it's hard to find dwarf loaches. And when I can find them, they're $20 a fish.
Otherwise, I'd love some. I love their scientific name, sidthimunki. :D
Olympia, are you sure about congos? Book says they are peaceful and tolerant and actually "timid in the presence of robust, hyperactive, or aggressive tankmates." (500 Freshwater Aquarium Fish, Consulting Editor Greg Jennings)
EDIT: Hey, clown loaches, I don't see you eating snails! Get to it, chop chop!
EDIT II: So far, everything I'm reading says they are shy and skittery. Maybe you're thinking of Buenos Aires tetras? They are aggressive and about the same size.
