Well he moves, but rather from the nessecity than because he wants to run away, hide or something. He acts as if he was a boa or other not active snake.
I once seen he had head in the bowl with water and there was fish in it, so I don't know wheater he was drinking or trying to catch the fish.
When i pick him up he does almost nothing, besides moving his head, flicking his tongue(he does that but rather less than my other thamnophis).
He is soft from the beggining but I thought it was because of too humid enviroment he had earlier.

I gave him these vitamins(b1, calcium and reptile vitamins) and he seems to have more reaction when I touch him and he even started running away, but I don't know if it is just my wish for him to get better or the real improvement.
I'll keep you posted.
