So I have a similar question. My pacman is about three to four inches across. I have been feeding him night crawlers they are about 4 inches long. I have fed him up to 3 at a time. I think he will keep eating. Should I feed him everyday at this size if he will eat. Does the same feed them till they stop rule apply if you are tong feeding them? Lastly, are night crawlers a good staple food. I put a little calcium dust on them every other time.
