So my Betta fish Shiro (he's pretty young about a year and a half old) has a weird hole in his side, it's actually more of a scab. I've been cleaning his water regularly, feeding the right feeding regimen, and examining him every few days and this popped up! (Here's a picture of his face, pretty normal lol I just actually got a good picture of him for once and wanted to show it!) (Here's his side! He has no backdrop on his tank so don't mind the junk in the background!) So I'm not completely sure what's wrong with him, he shouldn't have been able to cut himself because he has soft plants but you never know. Would water changes be the best way to go with some anti-fungal medicines to prevent infection or could it be something more serious? Thanks in advance!
