My salamander is sick and I don't know what to do. It just lays there and doesn't move. I know that it is still alive because I can see its heart beating, but I know that isn't going to last long. I'm still not quite sure exactly which species it is (cause they all look the same to me, or I just so happen to hit a rich vein of multiple salamander species in one place), but I think that it is either a Northern Two-lined Salamander (Eurycea bislineata), Southern Two-lined Salamander (Eurycea cirrigera), the Zig Zag Salamander (Plethodon ventralis). I caught them all when they were in their larvae stage, so it's hard to tell. some have went through metamorphosis already and look completely different from one another, and some havent even metamorphed yet and are getting pretty big; so I dont know what to think. Any help would be appreciated.
the one that is sick is the smaller one in the pictures below.
