About a month ago my black molly got ich so i QT'd her until 2 days ago. After trying Quick-cure for 3 days with no results i tried the heat + salt method. The whitespots disappeared so i waited 7 days then released her back into the main tank thinking the ick was gone. Well, today i noticed a white bump on the bottom lip of a neon tetra and a bloodfin tetra. Im not 100% sure its ich but it makes the most sense and sure looks like it. I want to turn up the heat and add salt to the main tank but im afriad I might harm other fish doing so. I have 5 cory cats, 3 ghost shrimp and 1 bamboo shrimp that im worried about. I know corys dont like salt and im not sure about the shrimp so i dont know how i should cure them. I thought about removing the corys and then heat treating the tank but what about the shrimp, will they be ok with high heat and salt? I dont think i can QT the bamboo shrimp since its a filter feeder and my QT tanks only have sponge filters (no current). I'm really frustrated with this ich!! Any help is greatly appreciated.
