Yes keep in mind the life cycle of ich is deceptive. Just because the white spots have fallen off the fish doesn't mean that it is gone from the tank yet.
Good info here to keep in mind:
"The life cycle of Ichthyophthirius is complicated but very important in understanding the treatment and prevention of ich. Once the ich protozoan attaches to the side of the fish, it begins feeding on the skin and tissue causing irritation. The fish's body begins to wall off the parasite to try to limit its damage. The protozoan continues to move around in the cyst feeding and growing, while the body continues to further encapsulate and wall it off. This encapsulation by the body is one of the reasons that ich is so difficult to treat during this stage of the disease because medications cannot penetrate through the wall of the cyst to reach the ich parasite. During this stage, the ich protozoan is called a trophozoite. The trophozoite eventually matures and is termed a "trophont." It will burst through the cyst wall and then fall to the bottom of the aquarium. It then begins to divide into hundreds of new ich-infecting units called tomites. This stage is very temperature-dependent within its capsule, with the fastest replications occurring at warmer temperatures near 78-80°F. At optimum temperatures, the replication will be completed in about 8 hours. At lower temperatures, the replication takes longer making the treatment time for eradication much longer.Once the replication is complete, the trophont bursts and releases the newly-formed tomites into the water. The tomites are motile and swim around the tank searching for a fish to attach to. Once they attach to a fish, the cycle will start over again. It is during this stage that ich is most susceptible to treatment. Many of the available medications will kill the tomites, thereby stopping the cycle of ich in your tank. It should be noted that these tomites will only survive for 48 hours, if they do not find a fish to attach to. These tomites will also attach to plants, filter material, etc. So if you move a plant from an infected tank into a clean tank, you have just infected the clean tank with ich. Depending on the water temperature, the whole cycle can take from 4 days to several weeks"
By waiting a few more week and performing a few gravel vacs you should be able to ensure yourself its gone
everything has stabilized in my tank yay! I had to move 3 platies I had in a small tank in my daughters room to my main tank as the filter died and I couldn't replace it until this week, so in my main tank (37gal) I now have 1 Dalmatian Molly, 3 upside down catfish, 1 mystery snail, 3 platies, and 1 Molly fry. I want to add in some new guys soon but having a hard time deciding what to add I'm thinking I may just get some more mollies but looking for suggestions of other tank mates for these guys before I make up my mind...
