what size tank do you have? that many fish would probably produce the ammonia you need to cycle in say a 10g, or maybe a 29g tank, but if you have them in a 55...or a 125? So, that being said don't remove your decorations when WCing. They also grow bacteria on the surface, but really its just too stressful for the fish. Stressed fish become sicker easier, and with the process of cycling, you'll have a lot of poisons going on in there. Finally, in order to determine that you've cycled you'll need a test kit of some kind. Liquid test kits work the best, and API is the cheapest. Also look into getting some seeded filter material from you LFS
. Good luck!
