we've got 7 guinea pigs... 1 netherland dwarf rabbit... tropical fish... and an asian water dragon
saying as you're interested in going down the lizard route here's some pigs of my Asian Water Dragon, it's only young at the moment so not possible to determine the sex, hence why i keep saying
it.
Slightly more expensive to set up than a bearded dragon vivarium, and the vivarium will need to be a fair bit larger too... an adult male will reach around 2.5-3ft nose to tail, and a female around 2-2.5ft they're also arboreal meaning they live in tree's, so they need plenty of height to be able to climb around.
The photo below is my vivarium, its only small as it has been split into two smaller enclosures, as a juvenile dragon would be stressed if released into the full size enclosure too early, once it grows a little more i will remove the partition and all it the full space available.
below a video clip of when we just got it home... aged 7 weeks
and another video of it eating a waxworm
