Not a homework question, but does anyone know how to identify fin rot? I have no idea, but every betta I had has had what I claim to be fin rot has died quickly after I noticed the curling up fins. I have a betta that has currently fins that are curling up and I fear that he’ll die like my previous bettas did. Is there a simple solution to this? I really want a simple solution. I want this to be answered by a professional, because my betta needs help. Thank you!!!
