Dr Roy,
This brings up an interesting question. I have a 'mantis hotel' that I have converted out of a 55 gallon tank (Still empty right now).
I currently have 5 mantis, and will be housing 3 of them in the sections of the hotel.
The species are:
1-O scyllarus
2-G platysoma
3-G chiraga
4-G viridis
5-G ternatensis
I am also looking to get a P cilata very soon, as well as the inevitable N wenn in a TBS liverock shipment.
Which 3 have the closest temperature tolerance range? I am going to house the heater in a 30 gallon sump, and I would like things to be as comfortable for them as possible. I am almost certainly going to put the O scyllarus in a 25 gallon tank that I have seperately from the 55,since he has less bright lighting tolerance, as well as a penchant (as you mentioned) for digging under/smashing through dividers to eat his little cousins.

PS: I seem to have stopped capitolizing the second part of the names (P. Cilata), this is the correct manner of noting them,I assume,since you always seem to do so.
