I agree with rob. With all the info you provided, I dont see a huge issue with transplanting into the new tank.
If you can- try not to disturb the fuge too much during the switch. The fuge will offer some added stability in the tank transfer. Does it have a sand bed?
Okay. Cool. The fuge doesn't have a sand bed. Should it? Am I supposed to let the new tank sit set up for a few days before transferring or can I make the switch at the same time? We plan on putting the new tank where the current one is at so running both would be very hard.
