I have lost a lot of snakes recently. I put it down to stress on some as i had moved my babies around a bit and some were strugling shedding. I put them into a viv of the size i think is big enougth and not over sized. Now I have lost 2 baby Floridar Blues. Simpton's are loss of appetite. I looked into a book and saw that it could be internal parasites but i dont know where they could have come from unless it was from the fish i have gotten. My big snakes are all eating pinkies and they seem to have still got their appetites, so it is only the smaller ones.
