This is my damage:
I knew it wasn't sturdy and just kept putting off trying to make it more stable, and I paid the price for being lazy. I was in Dunedin at the time so wasn't there for it, but my flatmate told me the rack on the left of the photo fell onto the wall on the right of the picture. There were two full tanks on the rack (the smashed one, and the one left on the rack (emptied too, huge crack down the front pane of glass)), and two empty tanks on the very top which survived thankfully. The tank at the top right of the photo was so lucky, bits of wood and glass all around it and it only has a small chip in the top (was the only tank with fish in except for one baby apisto in another tank). My other two tanks, 135L and ~80L were on a sturdy wooden desk and are absolutely fine.
The stand the tanks were on was a $30 Bunnings one and is about 4ft high by 70cm by 30cm. The pic I have posted is only 640x480 on my computer so I can't email you a larger copy sorry.
