I have recently received a gift of several dozen hissers. They were kept somewhat dirty. I pulled several babies out and put them in a separate tank. My question now, are they hissers? they have light colored bellies. very flat. some have a light band that runs around the outside edge. This wouldn't be the first time I have raised a bunch of "regular ole' roaches". But if they are native species, I would just as soon let them go... http://albums.phanfare.com/isolated/nSKKLPJK/1/5188325My link
