I've been looking for about 6-8 quarter sized fish (guppy size) to fill the mid upper part of my tank, but am having a hard time finding any that I really like, and are good in a community tank... well a semi community, there are khuli loaches a cory and a couple of the small suckers, and a female guppy for hte sole purpose of providing a live snack for the rest of hte fish every now and then.
