Let me say something neutral here (and getting it off my chest),
First of all if the fish is indeed 90cm long i think the tank of 125gallons (430+ litres) [4x2x2ft] would be a slight stretch for the fish. Other factors you have to take in is how thick is the tank glass. Fish this big you wouldn't want to mess with it when he got spooked in the tank + the amount of water pressure.
Secondly, regarding tank sizes, i noticed a trend in online fishkeeping discussions. People often like to "police" another person's tank sizes. Pointing almost every single problem to being the tank's size. If the fish is unhealthy, it's the tank size. If the fish is sick, it's the tank size. Or rather everytime a newbie asks a question about something the first reply he will get is, what is the tank size?
I believe this comes from people not understanding the different kinds of environment other people live in a country other than theirs. Not everybody live in landed housing and not everybody has the budget or space to allow such a big tank.
Right, one might say if one can't afford such a big tank then don't get such a big fish. Of course i don't mean one should put a 1ft fish in a 2ft tank. But as long it is appropriate with enough space for the fish to turn and swim and good enough filtration and most importantly, our maintenance of the tank/water, i think it will do fine. It's the same as one might argue, if one is not rich enough one should not get married and have children. Rich and poor people have children, there is a rich way to bring up a child and there is a poor way to bring up a child. Both ways ain't wrong. It is how one bring up a child to be a good person.
Regarding the question to transporting the fish,
Best way to move a big arowana is using plastic bags. I don't know what the folks in here call it but it's called Prawn Bags locally here check this out,

Drain the tank water to half or lesser, put in the bag at one end of the tank and let the fish slowly swim into the bag and quickly close the opening off and carry it out. Top up more tank water + oxygen if you're transporting for long. Refrain from sudden actions or trying to push the fish into the bag. In my own experience when i tried to "guide" the fish into the bag... it struggled and refused and even jumped. But when i just placed the bag in and let it swim in curiously by itself it's all over peacefully. But if you're getting from a fish store they should know what to do. Tubs or boxes without first containing the fish in a plastic bag would not be a good idea because if the fish struggle he will hit against the sides and injure itself. Plastic bags are used because so when they struggle there's nothing solid on the sides to injure itself.
In your home tank which i assume is all done up, filtered and cycled, float the bag and do the necessary acclimation of the fish.
Hope this help.
