Before you read any further I want you to keep in mind my state at the time. I had worked two double shifts back to back with 5 hours sleep and was only getting 4 hours sleep before repeating this. No, it's not overtime. I was very tired. Came home and being dedicated to my reefs, took a quick glance at them. Well, what do I see. In the nano, my boxer crab. Now I only see him about once a month. So there he is and what does he have in his claw? An anemone. I bought him w/o one. Now I bought a new (unknown) coral 4 days earlier and it had a single aiptasia on it. I was going to kill it I just didn't then. So I'm thinking wow where did he find a anemone? Then horror over took me. My lord, he is swinging around aiptasia. So I capture the little guy and the two won't part company and so I just cut off his claw. Have been living with terrible guilt ever since. Soooo sorrrry
