marm juvies problem

[eljorgo]

My larvae from the breddings on January are late but morphing.
I have sucessfull raise 7 larvae from juvies but this morning 3 of them were dead. I suppose that were the first ones that died Those who have morped 1 month or more. I didn´t get it... they were fine even yesterday and today were in a C shape dead... I puted them in a IceBox (one of those used for take to picnincs to maintain things cold) and after 1 week, give or take, this happened... most of them have eaten but sudentlly died... the frezing water box was laid just under them... cold it be just to cold?? I have recentry changed them to paper towels in the ground and i think i souldnt have do it:angry:...
any guess?
thanks,

Eljorgo

Hello,

for a better evaluation some more details would be helpful.
For example max./min. temperature and so on.

Greetings Ingo V.

I´m sorry Mr. Ingo The minimum temp was 9ºC and after 10h the temp is 20ºC. Again I put new ice and the temps start decreasing till 9ºC +-.
And this to all newts! all are fine and start eating even better. I put it out and they are fine no deaths.
They are now at the normal range of temperature 20 +- 22ºC.
I just don´t remember what more to say. they were/are in a plastic box with 15x10x5cm with paper towels, now almost all is covered by moss like before and they are doing great...

Was your water dechlorinated? Marms, in my experience, have been one of the easier newt species to morph and grow on, and once morphed, they are usually quite robust. Maybe there was a chemical on the moss or paper towels?
