Looks amazing...great work on the wood!
Now, granted I have no experiance with Mantis shrimp, however, from what ive read. they will scratch the glass up alittle. AND, they have alot of force when smashing things, and they might crack/break that acrylic. It looked very thin to me, but I cant really see the thickness from the pics. Im very jealous, I wanted a mantis tank for a while.
