My kid won a rosy minnow last Halloween at a carnival our church was having. I had an unused 10g, some filter plates laying around from a failed experiment, and a small powerhead that fit the pickup tube. I started out with the standard air pump setup, but the pump was old and thus noisy. I switched to the powerhead and it has been working well ever since. So, does anyone else still have a tank running this old school setup?
