Mucho Thanko.
Snap same mantis and tank.

I'm running mine without lights right now because of the heat issue. It gets some natural light being in a bright room but viewing is still less than favourable so will also be retro fitting LEDs. Good luck with yours mantis keeping is addictive .........
I cant really run without lights, I've got some button polyps in there and plan on having more corals as time goes on. The rock with the button polyps all over it is the one he calls home, he smashed up rocks and made a cave entrance, so I'd hate to have to take that out. I think turning the lights off and just letting the polyps dissolve isnt a good solution
So right now, since G. smithii supposedly tolerates temp and salinity swings and other stuff associated with being tide pool type critters, I think I'll keep running my lights. I need to get the LEDs up soon.
I so miss my mantis shrimps. I had several as hitchhikers on Florida rock. I caught them and they lived in my sump until I found someone who would give them a real home. I miss them so much. The most amazingly smart and tough animals in the sea I think!
Yep, I got rock from florida and had 3 small green mantis over the next year. I set up a little 2g tank for one and fed it freshwater snails from my cichlid tank, but it was hard to maintain a 2g saltwater tank, one drop of water evaporates and the salinity jumps a point. I eventually gave all the mantis, once I caught the crafty little beasts, to the LFS which they then turned around and sold for a hefty profit. Quite the racket
beautiful mantis! would love to set up a tank specifically for one some day
The cool thing is mantis are easy, smart and fun to watch. Smaller ones like this G. smithii are actually pretty interactive, I can wave my finger around and he threatens me, heheheheh. I dont mind when I'm outside the tank but if I stick my hand in there to clean, I'm going to be keeping a very watchful eye on him.
Anyway, a mantis tank can be really simple and small for a smaller mantis, and so far is a great source of enjoyment. I have mine at my office and it fills a perfect spot on my desk plus gives me something to look at when I need to quit staring at my computer screens for a second.
