My Eurycea Longicauda has lately taken to staying under a moss/mound overhang and all we can see is the head. It has been like this for about two weeks. Is this the behavior for guarding eggs???? I also just introduced another Eurycea Bislineata to the tank. Now I have 1 Bislineata and 2 Longicaudas and a female and new offspring of Cirrigeras. We are feeding them small and very small crickets. They are all in the same 10"x20" tank with all sorts of moss and grass mounds, rocks and hiding logs and a pond at the end. It has been made to resemble a wet, swampy, rivers edge and all seem to be thriving OK. Next question: Any warning signs or advice??? I realize the place is probably ready for another tank or two. What do you think???
