I am typing this for my 13 year old son Shawn. He loves to find mandids outside and put them in his tank. He has had one for a while now and it has 2 egg sac's in the tank. When he got home from school today his mandid was not moving much at all. He told me that he read they only live for 8 months or so, is this true? I am going to help him learn this forum and have him read, read, read!! He has such a passion for the mandid! Is there any other informationl websites he can visit to get more information? Thanks so much!!
