Wow Izzy's just so cute, reminds me of a caramel/chocolate-hardcandy stick :D yummi. Showed your viv to Aia, and she looked at me disapprovingly cause she want one just like yours xD
I guess you could put a bit of wood over the top, carve small holes so the lid latches make a more flush fit and so they don't take all the weight.
Not sure if I'd put another big boy tank on top but I could put a couple of smaller ones up there and keep a hatchling and a leopard gecko or something... hmm, thanks for the idea! If you could find out how your friend did it that'd be awesome!
Hiya
I spoke my friend again today and its not the big ones that she has stacked, its the 45cm x 45cm x 45cm and the 30cm x 30cm x 45cm. I've got a pic if you want to see it?
