I'm probably going to be upgrading my tank in the near future from a 75g to a 120g. I'm planning on having the old tank running at the same time as the new one and then move the livestock over. My big concern is going to be the health and well being of my mandarin. It's been with me over almost 2 years at this point and I'm worried that the new tank won't be aged enough to support it. I can't leave my old tank up until the new tank ages enough to support the mandarin. Is there anything I should do to ensure his survival?
