Thanks guys.
Sorry for the late reply, had a bit of trouble with my internet.
I keep them very similar to my pokies, temps between 22 and 27 degrees, humidity about 70 percent.
Seeing as they were all still small, they had quite a bit of substrate.
Also kept in deli cups, therafter in the same enclosures I use for all my others. If you look at my pictures you can get an idea of them.
Like you said Jake, maybe they just are my kryptonite...
Maybe I must try the H.lividum
