To Whitester - I don't actually have to move my fish till next year. At the moment I'm in student halls at university, but next year when I move to private rented I'm moving them from my parents house to where I am. My plan is to bag them all up in fish bags and put them all in a poly box. This way it can be stuffed with newspaper and stuff to stop them sliding around, and it'll be nice and dark so hopefully they wont be too stressed.
Then it's just a case of bagging/boxing everything else up and getting the car packed. I'm hoping it wont be too much of an ordeal.
To reedfish - Thanks very much

If you look at the 4 stages of the carpet you will see it looked ok (although sparse) at first, but then I obviously had die back, so it went all shrivled and curly until the new growth came through (2nd + 3rd), so then today I finally got rid of all the old shrivelled bits and spread out my nice healthy carpet. By christmas I'm hoping it will have filled in at least as much as in the 3rd grassy picture.
