Thanks Ratz, for your answer.
The pic hoster is a bit strange, yes and sorry.

Just to let you know, they are all ok. Skinned the sark spots off. I removed the complete bedding (wow, over 70ltrs of stuff :-))
Now its an all very clean cocohum and sand mix in there, which they seem to love more, too. :-)

The little girl, Sue, is eating again and all are doing well.

Thanks! Will post pix the next days/weeks.

Love, olli
