This is the Lysmata wurdemanni the Aiptasia eating peppermint shrimp. It is reef safe and its from Florida so it puts in work, not like its rival from the Gulf. I have found the ones collected from the Gulf are lazy and have to be trained to eat Aiptasia. You can easily train them by starving the tank and only spot feeding the Aiptasia. They will rip it apart to get the food and realize that they are food too and go to town. These guys are ready to eat Aiptasia once they get used to their surroundings. Peppermint shrimp ship free overnight shipping (50 pack or more) chose the invert only option at checkout. If combining with coral or fish choose the regular checkout. Orders over $250 ship free.
