I've been feeding him peas. He is eating them. I think I caused it, I know I did, I changed the tank all around and did a major change with the hardscape so I think I stressed him out to this point. I'm guessing when I moved everything in the tank I also moved his spot (unknowing) and caused this. Otherwise nitrates and all readings are fine. No other ailment in the tank at all. Now I find myself hoping for him to either burp or have a big fart lol! He's one of my favourite fishies so I have to joke a bit but trust me my goal is on saving him.
