I tore apart my filtration system and long story short my pumps outlet is 1 ft underneath the water pointing straight up shooting out 4200 gph. So basically there is a little geyser going on in my pond until I finish my new filtration system. I noticed something strange though, fish would intentionally swim into the "geyser" and get shot over 6 inches into the air and swim away. At first I thought they were just being morons and doing it accidentaly, and then I realized most of the fish that it happened to would keep doing it over and over again. I know fish like to swim against a current, but they were literally just shooting themselves up into the air! So back to the thread title, do you think fish are able to have fun? I am honestly just curious, I think it's hilarious, except for the fact that they almost shot themselves out of the pond completely a few times haha.
