Feeding
In nature most frogs are almost totally insectivorous. In captivity the tendency to use substitute foods is
one which must be avoided. The most common dietary problems seen in frogs are related to lack of
calcium or too much protein in the diet. Calcium powders are available at many pet stores and should be
mixed in equal quantities with a multivitamin powder then dusted on food before feeding. Place your food
insects in a plastic bag with a pinch of calcium/multivitamin powder and shake it till the food is well
coated. By doing this about 1/2 the times you feed your frogs, calcium deficiency will be avoided. Do not
mix large quantities of this mixture at a time. It does not store well after mixing as the calcium can
denature the vitamins (refrigeration will slow this process). Most frogs have not evolved to cope with a
diet high in protein and the tendency to feed them young mice or strips of meat on tweezers will put extra
strain on the frogs' organs, particularly the kidneys. If these foods are used regularly they will lead to gout,
irreversible kidney damage and ultimately death. Variety is the spice of life and even a frog knows it! Feed
your frog a variety of insects and invertebrates and you should have few diet related problems. Juveniles
will happily eat flies, moths, small crickets and cockroaches, and should have food available to them AT
ALL TIMES. If young frogs are kept warm and offered plentiful food they will reach breeding size in
about 8-12 months. Adults will eat almost anything that moves and fits in their mouth, they should be
offered about 10-20% of their own body size in food spread over 2-3 feeds each week. During winter or
when your tank temperatures are reduced your frogs will need less food. It is important to increase and
reduce food in both quantity and frequency with the changing temperatures of your enclosure. Remove
drowned insects so as not to foul the water, or feed your frogs individually by holding the insects on
tweezers.
