I was wondering if there was a dissess that makes fish where they cants swim or where they swim in circles the reason I ask is about a week ago I bought some alge eaters and they did that and died and a peloc that is now dead that acted fine all from the same store I want to know if this is just so happen to happen or what because now one of my guppies in the same tank as the algie eater is being loopy and I have him in a breeder net trying to save him because I'v had him for about two yrs I'v just trying to figure out if its just old age or something that I can cure that my other fish might get please help if you know I know hes just a guppie but hes my baby I started my tank with him about 2 yrs ago I'm kind of attached to him I really would like to save him if I could

It could be old age. May I ask how much are you feeding your fish?

I feed my fish twice a day...my guppy is still alive in the breeder net still being loopy and cant stay right side up and its been at least 3 days but I have been putting frog pelets in the net for him because they sink to the bottom and he seems to be eatting them some how because the fish food was just rotting on top of the water if there is anything you know that could help him I would be greatful

According to a diagnostic chart at animal world, it could be either flukes or swim bladder disorder. With swim bladder disorder, the fish typically swims upside down. I've never had any experience with flukes. Check out the link below.
