I’m currently battling my first case of ich and have, for safety measures ,removed my ivory mystery snail and guppy fry to the only think I had available (1g tank that I use to transfer water during water changes) and I am wondering if i can keep them in the tank while I’m combating ich with out a filter if I do daily water changes. (My 10g had 1black Molly,8 adult guppies, 1 guppy fry and 1 ivory mystery snail. I’ve had this tank running for quite a while fully cycled but after going out of town for a couple of days and using a release feeder I noticed my black molly had some signs of ich)
