Hello everyone, I noticed my swordtail Molly has a significantly smaller left side fin than his right. It looks milky white and damaged-looking at the end of it. However, none of his other fins look damaged. The only other thing I can see on him is a very very small sort of notch/dip in his dorsal fin. It appears slightly white tinged around it but other than that, he looks perfectly fine and is acting normal. Unfortunately I also just went through my second bout of ice since setting up my tank two months ago. I lost 4 fish from that. Could this be a result of the ich? So, is this fin rot, and if so, what can I do to help him? I attached some images where you can see the bad fin, as well as the little notch in the dorsal. However, the whiteness I see doesn't really show up in the photo. Thank you for any help!
