Moving the display tank

I need to move the 490 litre display tank that is in my lounge so that we can have new flooring put in. I only have some limited tank space right now (6 tanks spare, two of which contain fry), so have decided to temporarily lend some of my Hemigrammus bleheri to the 60 litre project tank.

I moved 2 females and 4 males on the 4th of January and am planning to move another 6 fish on the 9th of January. So far, the seeded filter has coped with the additional stocking without any problems (ammonia and nitrite are at a clear 0 ppm).
