Can you use distilled water for goldfish? Yes, but you shouldn’t—unless you’re mixing it or remineralizing it. It’s like asking if you can eat plain saltine crackers for dinner. You can. But why would you?
Your goldfish deserves a balanced life. Give it conditioned tap water, a filter, and maybe a plastic plant to judge. Skip the distilled stuff unless you’re a chemist with a hobby. Your fish will be happier, and you’ll have one less thing to worry about.
Now go check on Bubbles. He’s probably fine. Just don’t pour that jug of distilled water in there, okay?
