Hi Dr Roy, I stopped by at a local store to calgary Alberta, Pisces pet emporium. An employee there by the name of Andrew told me he has talked to you a few times. He told me he jumps at the chance to squire any mantis from their wholesaler. He keeps two of them in his own home, including a peacock. He runs t5's with his and told me I could run some soft corals up higher in the tank, as well as clowns, seeing as mantis' lack the imunity to the anemones sting. His is going on 11 inches and content with the numerous fish he shares his 29 biocube with. I am also intrested in a similar setup, what is your prefrence to peacocks choosing frozen over swimming and t5's causing shell rot.
