Hi! I plan to move my goldfish to a 45 gallon, and I’m curious about what kind of fish dan go with them. I currently have a zebra danio with them in the 20 gallon I am currently keeping them in, but I found out that zebra’s require a heater while goldfish do not. And even though I have kept them together for a long time, I don’t want the danio to suffer. Another dumb question but would separating them cause anything, like anxiety for the fish, or am I just being a bit paranoid.
