Lately, if you are sitting near my 2 gal betta tank, every once and a while you hear a giant 'BLOOOOP!' and a big stream of oversized bubbles goes shooting to the surface, scaring the heck out of my poor fish.
Is there something wrong with my cheapo comes-with-the-tank-kit UGF? Or is it the airstone?
