I really want a columbian RTB. I would like to get a male, the smaller size is appealing. What are the dimensions of an appropriate enclosure? How long does it take a RTB to reach basically "full size"? Do they make plastic tubs big enough, or are we talking only high dollar custom jobs? The care sheets lead me to believe that the care is basically the same as a BP, am I right here, or way off? Thankyou all for your help.
