Wild tamarins are omnivorous. They feed on flowers, fruits, nectar, insects, spiders, lizards, amphibians, snails, and other small invertebrates.
Recommended diet for marmosets should consist of:
2-5% Insects
5-10% Hi Protein (eggs, yoghurt, etc)
15-20% Fresh Fruit & Vegetables
75-80% Commercial Marmoset Diet (Dry or Canned)
Diet for tamarins is very similar to marmosets. Unlike tamarins, marmosets are known to be gum eaters. Marmosets differ from tamarins in having longer incisor and shorter canine teeth.
Vitamin A/D3 is important especially if they don’t have access to an outdoor enclosure. Vitamin D3 is needed for their bone structure. 1 drop per animal every day is enough. Do not overdose!
Fresh water is required at all times. Some people prefer to give their tamarin(s) baby milk.
A varied diet is very important to avoid boredom and loss of appetite. Feed them twice a day. Once in the morning and once in the evening.
Cut all food into approximately 1/2 inch square pieces
