My betta just died today I don't know what happened, but I just found him dead this morning. I clean my tank, ensure the water temperature is okay, and watch how much I feed him, so I'm not sure what happened. He doesn't have any fishmates with him 'cause he might pick a fight if I put other fish there. Right now I'm just emotionally and mentally exhausted. I'm not really good at handling losses. I feel like I did something wrong with my fish and that's why he died..
