MAntis breaking tanks?

[smy168]

I've been in the hobby for about 10 years now and though the rumours are rampant about specific Mantis Shrimps cracking tank glass, I have yet to actually spoken too... or seen pictures of... evidence of this happening. Can anyone crack this (what I call) myth for me?

Yes they do. Our group club just sponsored a mantis lecture by a UC Berkeley professor and he shown us pictures of of tanks in there lab that were cracked by mantis. So now they're using tanks with double panels for precautions.
