I got a mantis about a week ago and I have not seen him once. I'm not sure what species it is but he is a smasher darker in color. How long will it hide for? Do I not have the proper setup for it? He is in a 26 gal bowfront with two large pieces of liverock and I will be putting some sand in today. I have a mj 1200 for filtration and movement. Is there too much movement for him? Any help appreciated.
