Do your Guppies have ripped fins from nipping each other? I had one that died from fin rot even after I treated it and it improved for a few weeks before dying.

Guppies are inbred for their fancy tails, which makes them even more prone to fin rot disease.

Answer 2

you have not explained any symptoms etc
