Having learned my lesson the hard way, I would like to start using a quarantine tank for any new fish purchases. I've read the very helpful "ounce of prevention" article and the only thing I'm still not clear on is water changes - how often, and how much (%). I'm talking about one fish at a time, in a 10G bare bottom tank, with a cycled sponge filter. Thank you!
