Tiger pistol shrimp Digging and bulldozing 

I recently picked up a decent size tiger pistol shrimp and am constantly entertained by this little (big) guy.  He’s constantly making tunnels and dragging live rock rubble around to make his new pad. The only downade is he main steal some frag plus to sue as building blocks so glue your stuff down to avoid it being stolen bythis  master bullied!  I have even watched him try and stack a snail on his pile. Haha
