lol well luckily its not as heavy as it looks. its only made of light plastic too so its not too bad to lift out. The hardest part is stopping the water dragons jumping up my arm while im lifting the waterfall out lol.
No im not sure of the sex yet. Im hoping to 2 females but I think I might have to wait until they have done a little more growing to find out for sure. I will just be glad when they have grown a bit more and not so quick lol.
