I also feed mine every 3 days. just make sure that first poop comes before you give them too much. If they look like they really have to go, hold them and lightly message and BAM watchout. after that they should be fine. most of them won't need this done, but you should keep a watch for this even if you feed 5 or 7 days. with offering every 3 days I offer a little smaller than what most offer. In all the years I've been doing this, only had a few regurg. so this works well for me.
