Hahahah! Yeah, me too! It's all squishy/slimy and I'm always afraid somethings going to sting or attack me in the saltwater tanks. Especially one late night when I was reading up about all the hitchikers you can get in the live rock I was just getting chills all down my neck. I did have a mantis shrimp in one of my rocks that I flushed out. I thought I seen some crazy looking eyes peaking at me out of a hole one evening but when I got close it disappeared. Then, we heard some ticking in the tank and after I did some research I figured out what it was. So, I flushed the rock out w/ club soda and the ugly looking thing popped out it was about 3" long. I found some horror stories about it later on... I made sure it was dead before I fed it to George, our beloved Green Spotted Puffer. Here's one sick horror story...be sure to scroll down and see the person's hand split open...ewww...creepy...
