Josh,
I also have a lot of six from the same batch. Like you, I am new to this species and am actively trying to get information from experienced keepers regarding their husbandry. However, this has been my experience with them so far... Initially, I tried a shallow-water aquatic setup, but they all tried desperately to escape it. For that reason, along with the "talk" of sudden death in aquatically maintained Neurergus, I decided to play it "safe" an keep them terrestrially...at least for now.
I have the animals in somewhat temporary quarters; I am keeping them in separate plastic storage containers (with lots of ventilation holes) on moistened paper towel with a water source and flat stones/clay pot shards for them to hide beneath. I like this setup right now mainly because I can easily control the density of prey items; I can closely monitor what gets eaten, and I can eliminate any competition between the animals. At this point, I mostly want to make sure that all the individuals are feeding and maintaining good body weight. So far so good, although I am finding that these animals are relatively delicate feeders and shy (on land at least). Nevertheless, one of the strauchii took a cricket from a pair of forceps last night, so maybe they will grow bolder?
Good luck,
Sal
