I set a small betta tank on Friday. I was given a filter that has been cycled and was only being used to establish a new filter.
Today I have found out the tank has been hit with a fungus infection while the filter was still in tank which has killed several of his fish.
Have I just put the fungus infection into my tank by adding the filter?
