I want to get a qt tank but have a few questions. I do not currently have any sick fish, but have heard it is a good idea to have one on hand in the case I do have an outbreak of ich or anything else. First of all, will a 10 gal do? most importantly how do you cycle a qt tank, or do you need to? Do you have to have a qt tank running and full of water at all times or just when you need it? what else do you have to do to set up a qt tank, and what equipment is needed?
