My female betta fish contracted Ich last week, and I noticed it from a single white spot on her head. For the last 7 days I've been using Imagitarium's Parasite Remedy treatment in her tank, and when I bought it I was told it should only take a week, yet the little guy is still on her head. What else can I do?

Unfortunately, there are many organisms that can be white on a fish, not just Ich. Also, if it is Ich, it may not be cleared in one week. Since Ich is a parasite, it has a life cycle that it has to go through, which means there are many different life stages (eggs, juveniles, adults, etc.) in your tank. Only one of these stages is susceptible to medications, so the other stages will not be killed. Also, the life cycle is temperature dependent - this means that depending on the temperature your tank is, that the time that it takes for the parasites to mature from eggs to adults can take a long time. I would recommend having your fish seen by a veterinarian who is familiar with fish - they can take a small sample off of the skin of your fish to see if there is Ich, or something else, present. They can also perform a thorough exam of Freddie. I hope that gives you a place to start!
