if its the fine shredded aspen it shouldnt be a big problem...i used to use the regular aspen which has bigger pieces and that has gotten stuck in the past but i just pull it out...obviously i stopped using it coz it will get stuck and they couldnt pass it through. As for feeding in seperate tank well its not necessary, you stress the snake from moving it to another tank and most times they wont even eat unless youre doing live and thats even chancy...ive just always fed in their tank and keep my witts about me so i dont get tagged. One thing to do before you open their tub or tank is tap it so they know youre coming and then feed them. Good luck
