Getting “Peppermint shrimps”, loving them swaying back and forth while hanging upside down, and then learning upon adding an SPS coral that there are many Lysmata-species, and most like to eat SPS. I learned I had L. Bogessii. They picked my stylophora and birdsnest clean. The corals did survive though after I moved them to another tank. Also, the shrimps never touched the softies.
