Disease germs from previous tank
Hi, a while ago my goldfish got sick with cotton wool disease, slime disease and reddened fins. I moved them to a 60 gallon tank in which they all got better when I treated them with pimafix and melafix in the the new tank and are all healthy now. I rinsed out the old tank with water dried it out and packed it away. My question is will the disease germs still be in the old tank?
Thanks in advance
I don't know how to change the about me, but the biorb is the old tank, that is packed away, and I want to put a betta in it. My goldfish tank is fully cycled.
