Get fin rot medication from your LFS.

I usually euthanize when the cost of saving the fish is too much for me.

Apart frm that it has ich also. Cost of finrot medication 6-7 bucks. Cost of cheap ich medication 2-3 bucks. And there is no guarantee they will work.

Cost of guppy = 1 dollar

The fish may be cheap but it MAY not necessary to be the last problem you see unless you opt out of fishkeeping anytime soon. It's a good idea to invest in some good drugs, should it happen again in the future, they can come in handy.

In my case, I would euthanize a fish ONLY if it's deformed, stunted in growth, or infected with lethal diseases like glugea which can potentially jeopardize the entire fish stock unless it's important to me.
