Which species would you all say takes the least amount of maintenance?? Just the basic feed, water and occasional clean up? I have a friend that loves our little rascal and wants her own tort but she works 2 jobs and has kids and I would like to give her the best info I can on which would be best for her. She would need one that stays small b/c she has a small townhouse type yard. And if you think she just shouldn't have one in her situation thats fine too. Just let me know! Thanks!
