[Bruce&Izzy]

I'm really looking for some help and advise. I recently brought 2 hermans tortoise that I believe to be around a year old. I seemed to be getting on ok with them and moved around a week a go and now my Bruce has taken to sleeping a lot and I'm just a little worried. Temperatures seem to be ok but he is sleeping all day and night. I place him under the light and he seems to rouse a little then straight back to sleep. Can anyone advise what may be wrong? Tia
