Is This Fin Rot On My Swordtail Molly?

    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!

    I can't tell from this pictures personally, but it's possible, or something else is nipping it.

    Keep your water quality good and monitor it, if thing go on bad side you can use fin rot meds. But first be sure that no one is bullying that fish.

    I agree with appcontrol. It's hard to pinpoint whether it's fin rot or nipping, so your best option is to keep a careful eye on your setup.
