My sucker fish is continuously trying to suck onto my 9 inch koi in a forty gallon tank, don't worry I'm getting a 150 gallon tank soon. He did it for like...3? maybe 4 days then stopped for a week or so, then today he tried to suck onto my koi's head. Which, to teach the sucker fish a lesson, my koi smacked it away with his tail and swam away. Pretty funny actually. But, why is my sucker fish doing this? Does anyone know? Please help!
