I have a couple pointers that might come in handy... I have a 300 gal, and a couple 125s that I moved about 8 months ago. First of all a 125 is fairly heavy <assuming its glass> but nothing 2 people couldn't carry.
The second is how I moved all my fish and plants. I have only freshwater tanks but I assume this will work for saltwater just as easily and have minimal stress on all livestock involved. Walmart, and most other large stores of the like sell plastic multi use tubs with a locking lid in fairly large sizes. I have several 90L and 50L tubs made by rubbermaid I picked up for no more than $6-$7 a piece. I have also known people who have used CLEAN 35 gal trash cans. I filled all the tubs with water from the tank, placing the fish as separate as possible. I put a heater and bubbler in each and secured the lid. I then moved the tank to it's new location and brought over the fish after it was set up. This way I had a fairly decent percentage of the water the fish were used to, and had a situation where I didn't have to rush when setting up the tank.
Hope that's a little help.
