Well its gettin near time for me to get some more fish, and since i had the problem with ich i've decided to QT my fish before putting them in my main tank. I dont want to go through this mess again. I've obtained a 15 gallon with a Whisper 30 filter and a heater, which i've heard is sufficient for a QT tank. My question is do they have to cycle like the show tank before adding fish? Basically, I just need to know what I need to do to it to get it ready to hold fish for 2 weeks or so. Thanks!
