alLykaT66 Posted April 23, 2021 Share Posted April 23, 2021 Hi! My big sailfin molly has had this white splotch on his sail fin, not letting him completely open his majestic sail. Until a few days ago it turned red, and now I'm getting worried. He had this on him when I got him, an I really need advice on how to get rid of it or what it is. I got help from Petco and they said add Maracyn, so I've done that. Anything would help. I think it's a fungal disease, but I'm not sure. Thanks!
