Hi, I would like to hear from people who have successfully raised egyptians, I have been over researching the care of this species and I see and hear so many different ideas on substrates. I know many people use Oyster Shell. I know many people use a sand and excavator clay mix. I know people do a mix of the two. I know there is some experience with tortoises becoming impacted from sand…I have been reading and listening to everything I can. I am probably over thinking but I want to give them the best life possible. They will be in a large Smart Enclosure made by Mark Wilson. 8’ long x 30” deep by 30” tall. I understand the lighting and heating requirements. Right now I am just tying to make the best decision on Substrate. For the sand/clay mix…are you preferring the Home Depot play sand or a sand like ExoTerra Desert Sand or Zoom Med Repti Sand? In your responses if you could help me understand your reasons for your choices I would greatly appreciate that. My breeder is also giving me excellent information and support.
