I got this fish on Friday and he’s seemed fine. He’s been in my quarantine tank but he’s the first fish I ever quarantine so I might be doing something wrong. Anyway he was fine all the other days swimming around and pecking at stuff, but today when I went to feed him he was hiding and his belly looks sunken in and he’s also breathing rapidly. My water parameters seem fine except my ph was low (around 7). Can low ph cause this? Or maybe it’s not getting enough food? I put one of my live rocks from the main tank in the qt tank so it could eat algae off that between feedings but I don’t know if he does or not. If it is a good issue should I just put him into my main tank so he has all the sand and rock to scavenge food off of?
