I want to set up a smaller sized aquarium probably a 10 or 15 gallon, and I was wondering if using a sponger filter alone would be enough for airation and filtration. That way it's only one thing I have to plug in as opposed to two, and also I want to keep the current in the tank low. The only animals I want to put in there are a breeding pair of peacock gudgeons, a dwarf frog, and an apple snail.
