So I had a tank failure and had to move all my platies, guppies, and RCS into my clown loach tank. The tank is either 65 or 70 gals and dense planting. Moved the fish in yesterday and today 2 guppies have ich. So... if I treat the tank to save the guppies it would seem all the plants and RCS die. If I dont treat the ich the guppies and platies die. WTF?
