I want to move my amazon sword from one of my tanks. My question is would it be safe as my betta died of fin rot about a month and a half ago in it and i dont want to risk spreading it. ive only kept it running as it still has shrimp living in it.
Hello, Fin Rot is not contagious unless the other fish were being kept in the same poor conditions that lead to the Betta's demise.
What you can do is get 3% Hydrogen Peroxide, put it in a spray bottle with a bit of water, and spray the plant LEAVES, not the roots! and then wash it off, many fishkeepers do this to kill any bacteria or snails that have hitched on and are not welcome in the new tank.
It should help if you are concerned still to transfer it, but I wouldn't worry.
