Another thing to consider before adding loaches is the temperament of your cichlids. They might be okay with Tangs, but you should look into the level of aggression of each of the species to make sure it won't be too aggressive for loaches.
You might want to add to your rock work to give more hiding places for loaches. I think the leleupi and comps would like that as well. Mine like to hang out and also spawn in caves or shells placed in the rock work.
