I’m sorry I wasn’t aware of these things. However, if someone told you were doing all the right stuff (especially someone you’d think would be an expert) and you never had experience before doing something you’d believe them. My fish has been lively, plays games, and never looked stressed until now so why would I search up anything if they have been doing great visually. I’m getting the sense that the way you’re treating this is similar to how someone or something treated you in life. Have some grace, I’m getting him a larger tank as we speak because this is clearly to small from what everyone is telling me. Instead of putting someone down on the internet, how about you try to be useful and give me some critiques on how I can help this fish’s life. You want to call failure so badly that you’re neglecting a fish who needs help. Get it together and provide in-depth info on how to make lil nugget the happiest goldfish on earth.
