My goldfish died about 6 months ago and the tank has just been sitting their collecting dust. I am wondering if it is alright to just put my Betta in their without cleaning it. If I have to clean it what should I use to clean it? My mom suggests using bleach to clean it out but I have a feeling that will harm my fish, will it?

I find it hard to believe a mild issue such as finrot would ever kill a goldfish. Something else would.

You can use 10% bleach solution or potassium permanganate to clean the tank. Rinse thoroughly.
