Sexy Anemone Shrimp (Thor amboinensis)

The Sexy Anemone Shrimp (Thor amboinensis) earns its common name from a distinctive habit of rocking and wiggling its raised abdomen while perched, a motion that looks a lot more like a nervous tic than anything deliberate but has stuck as the species' defining trait regardless. It's genuinely tiny, usually found riding on the tentacles of an anemone or the polyps of a coral, and makes an entertaining addition to a nano reef that's too small for most other ornamental shrimp.
