Ok I asked my LFS and he said that last time he went to the wholesaler he saw a small mantis. So, I'm going to have my mantis not this, but next Sunday. I have about a 2-3" sandbed,not live, and about 8lbs of base rock. sounds good? I didnt think i needed to whole 20lbs of base rock, so i put 3 of the rocks in my 72g.what should i start out feeding him/her. I'lll post a pic with correct idnetification when i get her in.
