Young Male Guppy

[lilfishie]

as the title says its a young male guppy of my sisters (paige) that keeps spining any1 know why?

 

[tttnjfttt]

can you please give us a little more information, such as the tank size, tank mates, and water stats (ammonia, nitrite, nitrate, and pH)?

Does it look like it is having a hard time maintaining its balance in the water or that it just can't stop spinning in circles?

Right now, you need to isolate the fish because there is a possibility that it is whirling disease, which is uncurable and also contagious.
