Yeah I'l deffinatly watch out if i do; I've got 2 Vivs at the minute, one for Banjo and One for Lizzie but I'm having another 2 built at the moment so I'll probably house them together at first and watch them closely, see how they get on and if they start fighting I'll house them seperately. Upto about 5ft sometimes aren't they I just don't have the space at the minute for it, and it's going to be difficult enough to convinve the army to let me have Banjo, never mind a Monitor I looked into turtles/tortoises/terrapins last month, I like the idea of them but i think i'd get pretty bored after a while and that wouldn'tbe fair on it. I'm still considering it though .
