These guys produce Extraordinary kibble when tossed into a bio grinder. They raise by eating stone and only stone they get nothing out of anything else. They only lose 0.1 food every 20seconds or so you don't need to keep an eye on em. Fill a few troughs with stone and leave em be by the time they get hungry they'll already be past that 10% growth mark to eat out of troughs so no need to put stone in your maeguana
