Thanks to everybody for the advise. I really like the dwarf loaches and they are supposed to only get a couple inches long. I think they are kind of rare. I have only been able to find them for about $20 ea online. I guess maybe I should really look at cory's. Someday I will have more loaches though. I am concerned about having an appropriate home for them, though. That is why I found a new home for my clowns, and don't think think I will ever really have a home big enough for them but it sounds like there are are lots of other possibilities.....
