Hi, i have a mangrove monitor, its about 30 inches, do you think i need to get a bigger tank than a 40 breeder, Ive been thinking about getting a big 150 gallon reptile tank, also do you think mangroves can be tamed, because every time I try to handle my monitor he has like an episode and starts to freak out, and when im in another room i can hear him going crazy trying to climb out.
