When they are dark and you can't see their stripes they are considered to be unstable and when they have their cream,or gold color they are stable.There are many threads in the dat forum on the subject.
Yeah they are never dark just could not find anything about why they was cream color gave up looking and just bought them since the big ones at the lfs was all black and have not moved in 3 weeks. Thank you
Thanks I have been waiting 15 years to get Dat. One is eating pellets now to just get the smallest one to stop eating flakes. Wish I had room for that many but don't think I will go over 5
