So I bought a 10 gallon tank since it was on sale for Black Friday and already have it all setup now with a colonized filter in it. It’s got 2 heaters in it currently trying to warm it up to the right temp. I set it up about an hour ago now, and I’ve currently got my betta fish in the cup I bought him in, bundled in a blanket in an attempt to keep him warm until the tank reaches the right temp. I was wondering if there was a better or actual way to keep my betta fish warm while the tank heats up? It might not be done until the morning and I don’t want him to be too stressed out in addition to being too cold.
