My partner is taking care of my goldfish while I am away. It has developed an infection and I am hoping you all can help save my little buddy.
She originally thought that it was Ich, and treated four days ago with Super Ich Cure. It's continued to get worse, and this morning sent me a photo. The photo does not show clearly, but it is fuzzy. I told her to replace the filter and do a 25% water change per the Super Ich Cure directions. Does anyone have any suggestions as to what is going on here, or what steps she should take next?
