Sweet Hutton, no wonder my emerald crabs hide all the time, after writing that last post, I went searching for my second emerald...and I cant seem to find it... thats not to say it has been killed because this 5 gal is PACKED Full of tonga rubble stacked up in a tight castle manner with plent-o-hiding places! BUT, I also cant say I've seen it for many weeks... So for all intensive purposes, it MAY have been killed.... The other one hides near the wennerae's burrow entrance and waits for unwanted food... I have read that it seems like the Smithii may be more aggressive than the wennerae, but i believe that in general each mantis has its own "personality" and personal tastes for meals and friends....
