Ok I am kind of worried about him. He found a spot he liked as soon as he went in yesterday. I have not seen him move since. I can see a trail in the sand where he moved last night about four inches. But did not move when I touched him with the net. He is still breathing but his tail is side ways in the sand and half covered. His mouth is low on the glass. No sign of illness, is he just taking a long time to get use to his new home? I am just worried.
