Let's say that I had a platy in the hospital tank and he had ich. Later I put him in a different tank since he got better. Let's say I have a platy with a dropsy now. Should I clean the hospital tank before I put him in? Would fish diseases affect snails or shrimps?
Actually, I don't. I was about to clean my tank when all of these questions popped into my head. Should I clean the decorations in there with the vinegar/water solution? Okay and when you clean the tank do you fill it with water 9/10 and with water 1/10 and use a sponge to scrubb the tank? ???
yes you need to clean everything that is in the tank. You can use a sponge but it must be new otherwise there will be traces of soap still on the sponge. I use terrie cloth towels to clean my tanks, I have a stack that are for the fish tanks only. If it is a 10 gallon tank you only need to use say 1-2 quarts of water and like 1/4-1/2 cup of vinegar. After the wash make sure to rinse all of the decor and the tank out very well to remove any remaining traces of vinegar from the tank. The vinegar is toxic to fish.
