Lysmata wurdemanni size 0.5"-1.5", reef safe very peaceful.
Lysmata hochi size 0.5"-2", reef safe very peaceful. Tend to be a little larger than wurdemanni, may be a better choice if you have large fish.
Both eat Aiptasia.
Most varieties sold in stores are imported from Florida where they are caught by the 1000's in lobster traps. That's why they are cheap. That variety, called Lysmata rathbunae, do not eat aiptasia. They look almost identical to Lysmata wurdemanni.
