About feeding a frog / toad
Pet frogs range from tiny dart frogs to hefty Pacman frogs, but nearly all are carnivores that eat live, moving prey — and the two biggest mistakes are wrong prey size and overfeeding sedentary species into obesity.
How much should a frog / toad eat?
Aquatic feeding is measured as a percentage of body weight per day rather than in calories. The table below uses about 1.5% of body weight daily — always adjust to the two-minute rule and your animal's condition.
| Body weight | Food per day (~1.5% of body weight) |
|---|---|
| 5 g | 0.07 g/day |
| 38 g | 0.56 g/day |
| 70 g | 1.1 g/day |
| 102 g | 1.5 g/day |
| 135 g | 2.0 g/day |
| 168 g | 2.5 g/day |
| 200 g | 3.0 g/day |
What to feed
Frogs are carnivores/insectivores fed live gut-loaded insects (crickets, dubia roaches, and for larger species worms or the occasional pinky). Prey must be appropriately sized — no wider than the space between the frog's eyes — and dusted with calcium/D3.
How often to feed
Small active frogs eat every day or two; large sit-and-wait predators like Pacman frogs eat only every few days to weekly, as adults become obese if fed too often. Match frequency to species and body condition.
Common feeding mistakes
- Prey too large, risking impaction or choking.
- Overfeeding sedentary species like Pacman frogs.
- Skipping calcium/D3 dusting, causing metabolic bone disease.
- Handling frogs with unwashed or lotioned hands (skin absorbs toxins).
Weight & health
Obesity (in ambush predators), metabolic bone disease and impaction are the key risks. Right-sized, calcium-dusted, gut-loaded prey on a species-appropriate schedule prevents them.
Frequently asked questions
What do pet frogs eat?
Live, gut-loaded insects — crickets and dubia roaches for most, with worms or the occasional pinky mouse for large species. Prey should be dusted with calcium and appropriately sized.
How often should I feed my frog?
Small active frogs every one to two days; large ambush predators like Pacman frogs only every few days to weekly. Adjust to species and body condition.
How big should a frog's food be?
No wider than the space between the frog's eyes. Oversized prey can cause impaction or choking.
Can frogs become overweight?
Yes — sit-and-wait species like Pacman frogs easily become obese if overfed. Space meals out and judge by body shape.
