Drekkyk if you want a good barb cleanup crew go with Rosy Barbs. These fish are the biggest pigs I have ever owned (Bigger Pigs than my Goldfish). They will go through your substrate and cleanup any food that lands there. Since I got them, I don't see a single strand of hair algae on any of my plants. They dwell mostly in the lower/middle areas of the tank and make a nice colorful display. The alpha Rosy Barb does duke it out with the alpha Tiger Barb but other than that, these fish are very docile.
