Here is an update, I went to the fish store to buy the medicated food, but then found out that she was going down hill pretty fast that night. I saw her towards the bottom of the tank breathing harder. At one point I only saw one gill functioning and then the other gilll started working. Then maybe once every couple of hours she would swim around the tank ok. I also noticed my tang would come over to pick on him everyonce in a while. I really did not want to move her to the hospital tank and cause more stress but I felt that it was the best option at this point to prevent any other fish from picking on her and to give her a better chance of recovery. This morning she is still lingering towards the bottom of the tank. I am hoping that the vita chem will help. I will try to soak food in garlic to see if that will help her eat since she did not touch any food last night. Sorry for the long winded email, I wanted to be as descriptive as possible. I know that there can be a million reasons or factors why a fish gets sick, but does anyone think that internal parasites could be primarily be responsable for the fish being this sick? I have also read that parachlorometaxtlenol can be used to help the parasites. Any advice would be greatly appreciated at this point. Hopefully I can get her to eat today.
