you guys have helped me so much,ive learned tons just by reading posts on here.wehn i first bought my second snake about a month after the first,i put them both in a 55 gal tank because as you said thats what i had seen in the pet store.I instaltly noticed that my first snake stoped eating and didnt move much at all.I quickly put them in seperate conatiners.......the question i posted here was the result of the same misconception.when i bought my snakes they told me to give them one pinky about every ten days and dont over feed them.I followed that for awhile and then after about 3 months went up to a fuzzy.since i asked this question ive uped the size of my pray to a adult mouse and fed them one last friday and one today.......already they have been doing so much better.......my male is back to his old self and is as pleasent to be around as can be,he lets me hold him and pick him up wiht no fear or jumpiness.i swear i can see that he has grown a little in the past week.maybe im wrong but he looks bigger,thicker.now im preparing them a seperate feeding container for each one....im going to get heaters and such for the feeding conatiners this friday so i can leave them in there for a little while after feeding and not worry about the temps.my next question is this........the adult mice im feeding them now are about 1 1/2 to 1 3/4 the girth of the snake,and maybe 4 inches long or so.....the snakes handle them well......do i need to go even bigger.thanks guys for all your help
