@Tom can help you with this. Russians need a lot of room. Only one male to a group of females as they can get really aggressive to each other. Even then some may need to be housed alone. Good luck, hopefully Tom can give a more accurate answer as for how much room.
You got it and answered on this thread http://www.tortoiseforum.org/threads/how-much-space-do-4-russian-torts-need.132940/#post-1251069. Weird things happened. Explained on other thread.Sorry Barb. I can't see the question or the discussion about it. Catch me up to speed?
