how big is your enclosure going to be? Redfoots although small require a great deal of space, 15X9 is ideal for one tortoise. Reds are very active torts i have two of them in a 25x10x10 room i am not trying to steer you away from these animals but you should do some fact finding before even considering, getting one of these. There are plenty of care sheets on the net, and from how you described your viv. you dont have proper space for the hermans that you already have. So save you self some money and time and read a care sheet.
