I believe most people used Bubble Tips or Long Tentacle anemonees for Maroons, with Bubble Tips being most common. I hope you have very good lighting, water conditions, and a well established tank. These anemonees are fortunately among the hardiest for keeping in aquariums, but they still need good conditions. Good luck with your choice.
(P.S. your original post was early in the morning for many people. I think a lot of the ones who would respond did not get a chance before your second post.)
