So I have a 75 gallon that’s been up and running for 3 years. I also have my newly setup 225 up and running a week now with cycled rock. I’m trying to decide when and how to move everything over to the new tank. Rock, fish and coras will all be moving to a much larger space. They are currently across the room from each other now. How long would you wait to start moving things over? In my head it’s basically like moving a tank from one place to another but I’m still a little worried and don’t want to lose any critters. Only thing not coming over to the new tank is the sand.
