Old fire bellies seem to be starving, other two old guys are fine.

I feed them regularly and constantly, but two of them are seeming not to eat. I have isolated them for the night, but they seem very skinny. I never really noticed it until today (I don't pick them up except to clean their tank every 3 weeks or so). I am sure they will live through the night, and I will buy some more crickets and baby waxworms tomorrow. I have had them since around 2008 or 2009, so they are quite old for fire bellies, but I don't think its time for them to die just yet, is it? I hope not, theyre my guys.

They don't sound that old,but older animals do tend to fade away, have you done any thing different lately, added pond plants etc to the enclosure that could have brought in parasites or diseases? try to see if they feed, if they have difficulty catching the insects, they could have a vitamin A deficiency ,this can cause visibility problems, often seen in tongued amphibians, they miss the insect each time they try to feed. Wax worm larvae can also be hard to digest so if they are unwell soft bodied crickets or even fruit flies may stimulate their appetite more.
What is the set up like is it warm enough for them? are they active other than not feeding, tell us as much about the set up as you can and some one may have an answer for you.

Have you introduced any new firebellies and were they quarantined?
