I want you to know that you will not do well with it in a big enclosure.These snakes are found in small,cramped and tight places remember.I find it best to put such a small snake into a deli cup with holes in the lid(of course).The water dish is easy,take a dixie cup and cut a V in it,these fit snugly under the lid of the deli cup.It is important to regulate proper temps and keep the substrate clean and dry AT ALL TIMES,for this I prefer paper towels.By the way,I have NEVER heard of ANYONE successfully feeding milks fish or slugs and I definately would not recommend it to a beginner.If the snake refuses food for more than 3 weeks be prepared to let it go.Dont worry about outside temps for release,I have found milks active in Mass.the 2nd week of deer season(2nd week of DEC!)and put them in my pocket.....where they stayed warm and happy the rest of the day!Jeff
