I read that if goldfish gulp too much air when fed floating foods, it causes a problem in their stomache(or somewhere else) causing them to not swim well(?)
but what about the relative; koi? i've seen and you're probably seen alot of koi gasping at the surface for food. does the problem that occurs with goldfish not affect koi?
