Also, I'm using aspen shavings right now, but plan on changing to the coconut type when I do a complete change over. But for now I'm wondering if it's ok to feed him in his tank on the aspen, I don't have another tub or dedicated feeder tank and yesterday I heard that you shouldn't feed them on the aspen, which I have already done once. And should I invest in a tub or something as a dedicated feeding place?
