FS Mantis Tank

[viperfish]

I set the tank up with deep sand, one large piece of LR and a whole bunch of large LR rubble. She has built tunnels underneath the large LR and used the smaller pieces to build up the entrace to the tunnels so the sand doesn't slide in, and to cover the hole if need be. The most impressive thing is the intricacy she has used to put everything together. My Wife and I joke about it calling her a little Engineer! The really amazing thing is she lets the Six Line Wrasse swim in the tunnels and doesn't bother him at all.
