I just bought a aquaclear 70, big Als was selling it for 19.99!! I could use it for my 10g that Im working on. I'm not sure what kind of fauna I will have in there...What wouldn't I be able to keep with that filter if I decided to use it? ex. Neons, I have baby lyretail swords that I was thinking of putting in there once they got bigger and the tank was cycled, cories, shrimp maybe?
