I got my two new Mali Uros Saturday. They are 6 months old and pretty tame. They were not interested in eating the veggies I offered the first day, but they did eat some Hibiscus flowers. Yesterday and today they ate a little more. How much should they be eating at this age? They are very active during the day, and they appear to be in good health. They don't look too thin, but they are not as fat as some I have seen here.
