Looking for a Small Mantis shrimp species

[WilliamH2529]

I'm setting up a nano reef tank for a mantis shrimp I'm not that picky on the particular species but I do have 3 or so in mind, Those three would be the Purple spot mantis shrimp( Gonodactylus Smithii) the Lime Green Mantis Shrimp(Gonodactylellus Viridis) the Tiger mantis shrimp( Gonodactylaceus Chiraga) or finally the Orange spot mantis shrimp, I'm just looking for any of the smaller ones, if people have another species not mentioned and its a small smasher type I'd also be interested.
