The Sexy Anemone Shrimp (Thor amboinensis) is a colony animal at heart — a lone Sexy Anemone Shrimp just perches and wiggles at nothing in particular, but a group of three actually clusters together on a host anemone or coral the way they do on a real reef. Sold as a trio because that's the minimum for the behavior you're actually buying this shrimp for, at a lower per-shrimp price than ordering three separately.Includes: 3x Sexy Anemone Shrimp (Medium/Large)
