sounds good jessie,they will love it mate,u wont regret doing that mate,and they will all get on ok,i found my easterns would get a little defensive at first when the blueys went near them but after a couple of days they were fine,have never had any probs with them being housed together,just have to take gravid blueys out arond the time they give birth as i seem to have lost one litter this season,the water dragons have been seen to nip at them when they r born so probably ate them,apart from that its all good
