FYI - the thing about the pump is for oxygen (plants take up oxygen too and can be a contributor to fish not having enough in a small tank) If you can figure out a way to make bubbles that break the surface of the water - like a tube that draws a small amount of water from the pool and releases it onto the surface, this will add oxygen into the water and everything should be fine (it can also be fun to set up some sort of waterfall thing, and again the water falling into the pool and breaking the surface layer, will add oxygen into the water for plants and other things.
