yup, thats right, my mantis got me. I had my hand inside my 6g eclipse mantis tank cleaning up stray macros, when my 1.5" smasher decided he didn't want me there. I grabbed the macro, with my knuckle facing his hole, when he came out and bashed my finger. It didn't hurt that much, just felt like being flicked really hard. I did break the skin and bleed. I was more surprised than anything, because I put my hands in their all the time. I think the reason why is becuase he hasn't been given a stoma snail for a few days, so he was hungry. I immediatley washed it off with soap, to get rid of germs. I thought it was kind of cool, but was glad that he wasn't a 6"+ peacock.
