yes , I have F1 merus which are 10 months old now. It is your opinion. I only wrote my experience. Horns are like nails or hairs and you can guess on healthy.
First, their coloration is not normal. I saw colors like these on ill animals. Second, their horns, it tells me they are min. one month in bad conditions (low of food, bad vitamins and minerals rates). Young merus are so sensitive for these.
Fabián, this is the best news I ever seen on this forum. Congratulation!
I have a few questions: how many was born, how many survive first day and when did they eat first time?
My merus are in winter indoors where is temperature still about 60 F without any spot only with UVB. In this time I fed them max. twice a week and min. once a week.
That is true, merus are very resistent with low temperatres. My animals are still outdoors too.
I found this graph with temperaures in Arusha in article: Presumptive habitat of the African arboreal theraphosid spider Encyocratella olivacea STRAND, 1907 (Araneae, Theraphosidae, Stromatopelminae)...
