What is the best fin rot medicine that is easy to get

hi it’s about 9:30 at night rn and one of my guppies has fin rot. and that’s the only medicine i don’t have on hand rn. i’ll have to wait til the morning but what’s the best fin rot medicine that’s easy to get. anything from petco, petsmart etc? i don’t know how my fish are even getting sick i do weekly cleans and i haven’t introduced any new fish or anything for a month or two. this guppy is 2 -3 years old, could it be just age? cause she’s the only one that has it for right now? anyways please help

 

Frequent partial water changes are pretty easy to get. So is stress coat or aquarium salt as well.

i have aquarium salt. so how would i do that. daily water changes? how much water should i take out? and i’m guess i would add some salt after each waterchange?

 

Fresh water is the best treatment, i would wait before adding salt. But A stress coat product wont hurt anything.
If you really think you need aquarium salt, first be sure that you do not have fish that dont tolerate salt = catfish and scaleless fish, loaches, most bottom feeders.

you can add one tablspoon of salt for every 5 gallons of water. toss it in or dissolve in tank water first, doesnt matter. I would be wary of adding more salt. if you dont have a hydrometer, you never know how much salt is still in the tank. Even if you do 100 % water changes, you don't know how much is left in the gravel. I am not big on salt for freshwater fish, and hopefully others will chime in.

It really depends on the fish and depends on the plants but a guppy can handle salt very well.
Salt will kill the bacteria eating the fins and fresh water will help the healing.
You will eventually dilute the salt out with water changes.

So change some water...dose some salt....wait a day or two and repeat if necessary.

Guppy fins grow back fairly quickly so you will see results in a few days. At first the newly grown fin will be clear but will soon color up.

But wait....there's more.
Fin rot is 98.999% of the time collateral damage from something else going on.
So healing the fin rot is either going to be a bandaid for a bigger problem or the fin rot won't heal at all.
Do you know what is causing the fin rot?
Might want to fill out the emergency template to see if we can pinpoint any other issues.

.... this guppy is 2 -3 years old, could it be just age?

Ummm....yep. But let's not say this is the reason until we rule out anything else.

Let's start with water parameters and tank mates.
