Last week I noticed some white spots on my bronze cory, but they were gone the next day. This morning I noticed some spots floating around the tank. They looked almost like tiny bubbles, but they didn't really follow the current like a bubble would. I'm going to use the heat treatment to hopefully get rid of it once and for all. Even if it's not ICH, I'd rather be safe than sorry. I don't have the space to quarantine new fish, so the new cories I added could have brought the disease in. Here's my plan: (correct me if I'm wrong) -Increase the tank temperature every couple of hours until it's 86 degrees F -Frequent water changes and gravel vacuums -Bring the heat back down after two weeks Any suggestions? Will this harm any of my fish, fry, or inverts?
