unfortunatly the guppie died today, i did not notice it ontill tonight but neither did the other fish as it was floating at the top at the side.

my other f guppie is starting to do the same as wot the other fmale one did it is not as bad but there are early signs of it happening again. why is this only happening to my female guppies?
