the major drawback to owning a retic is there size, while it may seem like a good idea when it is an 18 inch hatchling, you may change your mind when it is approaching 10 feet in the first 12-15 months, and even more when it hits the 15-18 foot mark and eating full grown rabbits.
there size also becomes a problem when trying to move them for cleaning and maintenence if you are the only one around.
here is a pic for you
but if you really like retics, i would look into dwarf retics, all the beauty and personality of a retic, only in a 7-10 foot package.
