A friend of mine had one of these and didnt know it. It came as a hitchiker. The same night he got the rock, he kept hearing this loud clicking. He was moving rock around trying to find out what it was when it hit his middle finger. He thought his finger was broken and it left a nasty bruise. The mantis cracked his 30g tank that night. Glass tanks are no good with these guys. You can look up vids on youtube and you will see what I mean.
