Not sure what the "Loachy dance" is but I know the clown loaches always seem to be extremely active when I have seen them. Perhaps that is what it refers to. From what I have heard, I don't think you will be disappointed if you decide add loaches to your tank. I would love to keep some of these but am afraid my tank is too small. I am going to settle for the smaller panda cories. But will definitely get some when I get a bigger tank someday.
