"If anybody out there can tell me why my little fish that I have had him for about 7 years now maybe longer but anyway all the sudden today I hear this noise and I go look over at my tank and he's laying on the ground he completely leapt out of the water. I only have the two fish in there I have a koi that I rescued from my pond outside. I don't know of a reason why because I just changed out the water, I just changed out the filters, everything looks good and I give him pallets food and everything else but all of a sudden he decides he's going to go take a flying leap he bruised his belly really bad he's still alive but I don't know how long. So if anybody's got an idea of why he decided he was going to take a flying leap can let me know, appreciate it because I don't want to do it again. Thanks"
