What's funny is that he hasn't tried to attack my finger through the glass (and he seems very interested in people!)... Both mantis shrimp at the other lfs both did and I think that's why I couldn't leave Aqualife without him! Went in to pay for my puffs and told myself if he was still there, I'd take him home... So he now has a 10g all to himself; moving into a bigger acrylic tank when he gets a bit bigger (since I won't trust him in glass once he looks like he could do some damage lol) He's only about 3 inches long right now.
Edit: OMG! As I was moving my serpent star and hermits to the 29, I found the tiniest little brittle or serpent star(leg span about nickel sized) living in/on a specific piece of lr!!! I was so amazed! Little baby stars are just too cute!!!
