Only problem I see with shipping larger Colony's is them breaking during transit. almost impossible to ship them without some sort of breakage. Also the cost of shipping is crazy! depending on box size, weight and dimensions determines how much shipping will be. I ship 1.5 lb boxes and costs me from $55-$65 in a 6x6x5 box. something to keep in mind
I would agree with zygote in trying to sell them local then start over, just so many variables with shipping. unless you have some very rare pieces that you can have a buddy hold until you get new tank set up and stable
