I might have to wait because my son a couple of nights ago emptied half a jar of pellet food in the tank. since I have been working late the last couple of nights I did not check out the tank until this morning. percs, hermits, snails & zoo all were dead that is the only problem with a 12 gal nano no volume to offset one of your kids deciding to feed tank. I guess putting pods in a non-cycled tank would kill them.
