Frogs are carnivores meaning they eat only meat. For small frogs, that means mostly insects. Knowing what insects to feed your frog is a matter of considering both natural habitat and size.
Insects for Land Frogs
Small land-dwelling and semi-aquatic species of pet frogs such as the fire-bellied toad can snack on a healthy range of commercially available live insects that your local pet store carries. These include:
- Wax worms
Before feeding your frog any of these, dust them with reptile dietary supplement powder, available online or at your local pet store. This adds calcium and other vitamins that captive frogs do not get enough of through other means. Choose insects that are less wide than your frog's mouth to discourage choking. Remove uneaten insects daily.
While larger frogs can eat mice and other vertebrates, do not try to feed these to your small frogs. Not only are they overly fattening if fed too often, but they can cause choking or other health issues if not digested properly.
Worms and Shrimp for Aquatic Frogs
Feeding a small aquatic frog such as the dwarf frog is a bit more tricky. Fortunately, they don't require live food the same way that land frogs do. Place a small terra-cotta plate or disk on the bottom of your frog's aquarium. Aquatic frogs will eat:
- Livebearer fry, like guppies
- Frozen or freeze dried shrimp baby shrimp, krill, brine shrimp, bloodworms or glassworms
- Frozen beef heart
- Nightcrawlers or bait worms chopped into small, bite-sized pieces
Prepare your frog's food in a small bowl and defrost if necessary. Use a turkey baster or similar instrument to suck up a small bit of food. Dip the baster into the water and squirt the food onto the plate you placed earlier. Allow the frogs to eat their fill then suck up anything uneaten and discard.
If you are unsure what type of food your specific frog should be eating, contact a herpetologist for more information.
