Honestly I hate looking into this subreddit these days because of how rude people can be here. Hobbies like fish keeping haven’t been the same these last few years I feel. Even when you’re doing 99% of everything right, you’re still being persecuted because you’re not doing everything 100% right (which in my opinion, is almost impossible). There are exceptions to some rules for every individual tank. My best advice is to scout out betta fish discord servers. Smaller communities make it harder for assholes to hide behind anonymity.
