Mantis shrimp/Remora Question

I have a friend that started a 55G marine aquarium found a Mantis shrimp in there, I advised him to take it out because I remember someone on here waking up to squishy carpet. He has trapped it and has it in a breeder net thing in his tank. It's about an inch long. He was wondering if anyone in the Tampa area is interested in purchasing it or making some kind of trade for it. I traded him some live rock for a Remora about a foot long that will outgrow my 125 G tank quickly if anyone has a huge tank that would like a Remora I'm willing to trade it as well. Figured I could help him start his tank and save the Remora as well. It ok for now in my tank but will get huge soon.

 

Do you know what kind or at least color of the mantis?

 

He sent this picture below. I'm not sure about what kind.

 

Remora has a new home. In a 2800 Gallon tank. Loving life. More like a pond. Saltwater Pond.
