Mothra, definetely my favorite mantis Ive kept is the Chiragra. And regarding them breaking glass...well its possible but fairly rare, the stories (creditable ones) of them bustin out and looting your home for valuables/eating all your food/and maxing out your credit card are few and far between. Unfortanetely when it comes to what mantis to get it usually boils down to what mantis you can get rather what you would like, of coarse the O.s.'s are fairly readily available at a cost, but you definetely do not want to put a smasher that would get that large in a ten gallon tank (well not at least under the idea its a long term setup). Another stomatopod that is readily available (usually as a hitchiker from a hobbyist who is worried about the beforementioned consequences of one getting loose) is the N. wennerae which would be great in a ten gallon glass tank. Also regarding refugiums they are usually run reverse daylight (i.e. the lights are on when the display tanks are off and vice versa), which may or may not be a good thing when it comes to viewing these guys. But then again that is all personal preference when it comes to your tanks needs. Ok well Im done rambling, Ill leave you with this though, if you come home notice the tank is emty, your wallet is missing, and your credit card couldnt pull down a snickers bar its best to just move on to the next town and start over....the mantis has won this round.
Cheers,
Brian
