I have 7 right now (two more coming the beginning of next month). I handle usually every other day when I check their water. Of course if one makes a mess they are the lucky one to be handled when I'm cleaning up after them lol. I don't handle for two days after they eat, or when they are in shed. My two new babies I handle every day for about 5-10 minutes but I take my adult out probably 15-30 minutes every other day...not all at once. Mine are all pets, and I will be hobby breeding probably in about 2 years.
