That show makes me really angry because they basically go, put the tank there, add water from a hose, add fish, voila instant fish tank. And it don't work like that!
They have to edit it out of the show so their show fits in the time length. They actually acclimate them all and everything. They are thinking about adding it in the future episodes though because many people have said the same thing you said to them. "Why dont you guys acclimate the fish, cycle the tank....blah blah blah"
Also, they add in the drama and crap for the kids who may be watching. They try to make it a family friendly show.
The only thing I hate is they stock some tanks really unprofessional...for instance the keg tank they made, they put in a huge fake coral insert and added like 30+ african cichlids and all they can do is swim in circles...horrible
