Hi, my name is jake im fairly new to the hobby only about a year or so, but this is my first posting on here. I was wondering if anyone knows what is on my plecos tail it almost looks like a fungus that flows with his tail its also on one of his front fins, i've tried a few things to get rid of it but no luck, if anyone has any ideas how to treat it let me know, thank you.
