Best Reptile Food by Species: Dragons, Geckos and Tortoises
Zoo Med Natural Bearded Dragon Food leads for omnivorous lizards, needing no gut-loading and holding a workable calcium ratio out of the bag. Crested gecko keepers do better with Repashy Superfoods Crested Gecko MRP, a complete gel diet. Tortoise owners should reach for Mazuri Tortoise Diet, built around the fiber tortoises actually need.
Reptile diets split by species far more sharply than dog or cat food ever does. Zoo Med Natural Bearded Dragon Food leads for omnivorous lizards, since it needs no gut-loading and holds a workable calcium ratio from the bag. That still will not cover a tortoise’s fiber needs or a gecko’s soft gel diet, so species specific picks follow below.
Labels rarely spell out crude protein, calcium to phosphorus ratio or filler content in plain language. Owners often end up buying a formula built for the wrong species entirely. We compared guaranteed analysis panels, ingredient order and feeding reports from bearded dragon, tortoise, gecko and turtle keepers to sort real diets from generic mixes.
The top picks, ranked
Zoo Med Natural Bearded Dragon Food
This extruded pellet blends alfalfa, vegetables and insect meal into one daily diet for adult bearded dragons. No gut-loaded crickets or chopped produce are needed to hit a workable calcium level. Owners report dragons accept the pellet texture within a week once softened with a little water.
Pros
- No live insects or produce prep needed daily
- Balanced calcium level for adult dragons
- Long shelf life in a resealable bag
Cons
- Some dragons refuse dry pellets at first
- Not appropriate for juvenile dragons needing more insects
Repashy Superfoods Crested Gecko MRP
Mixed with water, this powder sets into a gel covering a crested gecko’s full nutrition without live feeders. Fruit and insect protein sit alongside added calcium and vitamin D3. Breeders use it as the sole diet for gargoyle and crested geckos across multiple morphs.
Pros
- Covers full nutrition without feeder insects
- Comes in flavors geckos accept readily
- Mixes in minutes and sets in the fridge
Cons
- Unused gel spoils within a few days
- Powder clumps if stored somewhere humid
Mazuri Tortoise Diet
Mazuri built this pellet around the high fiber, low protein ratio tortoises need to avoid shell pyramiding. Soaking it in water before serving mimics the moisture of grazed vegetation. Sulcata, Russian and Greek tortoise keepers use it as a base diet alongside fresh greens.
Pros
- Low protein formula suited to tortoise metabolism
- High fiber supports normal shell growth
- Soaks into a texture tortoises chew easily
Cons
- Needs several minutes of soaking before serving
- Some tortoises prefer fresh greens over the rehydrated pellet
Zoo Med Aquatic Turtle Food
These floating sticks hold together in water long enough for a turtle to bite off pieces at the surface. Shrimp meal supplies the higher protein aquatic species need compared with land tortoises. Owners of red-eared sliders and painted turtles use it as a daily staple alongside greens.
Pros
- Floats and holds shape for easy feeding
- Higher protein matches aquatic turtle needs
- Reduces water fouling versus loose flakes
Cons
- Uneaten sticks cloud tank water if left too long
- Not suitable for land tortoises or box turtles
Zoo Med Can O’ Crickets
Real crickets packed in water skip the cage, chirping and escape problems live feeders bring. Leopard geckos and other insectivorous species take them from feeding tongs with no gut-loading step first. An unopened can sits on the shelf far longer than live crickets ever survive.
Pros
- No live cricket escapes or chirping
- No cage or gut-loading setup needed
- Long unopened shelf life
Cons
- Lacks the gut-loaded calcium boost live feeders can carry
- Some geckos notice non-moving prey more slowly
Fluker’s High Calcium Cricket Diet
This powdered diet feeds crickets and mealworms for a day or two before they become dinner, loading their gut with calcium. Insectivorous reptiles absorb that calcium secondhand, cutting the need for dusting every feeding. Breeders keep a tub on hand alongside a regular cricket keeper.
Pros
- Boosts calcium reptiles get without extra dusting
- Works across most common feeder insects
- Inexpensive relative to the feeder insects themselves
Cons
- Only effective if the insects actually eat it first
- Adds an extra step versus ready-to-feed diets
Fluker’s Buffet Blend Adult Bearded Dragon Formula
This pellet mixes dried vegetables, fruit and insect protein into one bag at a lower cost than boutique formulas. A named protein source still leads the ingredient panel, ahead of fillers. Owners keep it as a base diet and add fresh greens a few times a week.
Pros
- Lower cost than premium single-species formulas
- Named protein source listed first
- Resealable bag keeps pellets fresh
Cons
- Lower calcium level than top-tier formulas
- Still benefits from fresh greens on the side

How to choose
What makes reptile food premium instead of generic Premium reptile food names a real protein source first on the ingredient panel, not a vague meal or filler grain. It also states a calcium to phosphorus ratio close to what the species needs in the wild. Cheap mixes often skip that detail entirely. Fat in insect meal turns rancid faster than most owners expect, so freshness matters too.
Matching diet to species type Bearded dragons and other omnivorous lizards do well on a pellet with moderate protein and added calcium. Tortoises need the opposite: a low protein, high fiber mix that avoids overly fast shell growth. Crested geckos thrive on a complete gel diet that replaces live insects entirely. Aquatic turtles need noticeably higher protein than any land species on this list.
Pellet, gel mix, canned or gut load: picking a form Dry pellets store the longest and cost the least per feeding. Gel mixes need refrigeration once prepared but suit species that refuse dry food. Canned feeder insects solve the escape and odor problems of live crickets for insectivores. Gut-load powders are not food for the reptile at all, since they feed the feeder insect first so calcium passes through secondhand.
Calcium, protein and the ratios that matter most Most reptile species need dietary calcium to outweigh phosphorus by roughly two to one. A mismatch over months contributes to metabolic bone disease. Insectivores usually need the least added calcium in their base food, since dusting or gut-loading covers the gap. Herbivorous tortoises need the least protein of any group here, while aquatic turtles need the most.
Good to know
What is the best food for bearded dragons?
A pellet with a named protein source, moderate crude protein near 18 percent and added calcium works best as a daily base. Zoo Med Natural Bearded Dragon Food and Fluker’s Buffet Blend both fit that profile. Fresh greens a few times a week round out the diet for adult dragons.
Can crested geckos eat only powder diet?
Yes, a complete mix like Repashy Superfoods Crested Gecko MRP covers full nutrition on its own. Many breeders raise crested geckos for years on the gel diet alone. Occasional live insects add enrichment but are not required for basic health.
How often should you gut-load feeder insects?
Feed crickets or mealworms a calcium gut-load diet for 24 to 48 hours before offering them to a reptile. Shorter windows leave too little calcium in the insect’s gut to matter. Keep gut-loading insects continuously if feeding daily, rather than only right before a feeding.
What do tortoises eat in captivity?
Most grazing tortoises need a high fiber, low protein diet built mainly from leafy greens, weeds and a commercial pellet like Mazuri Tortoise Diet soaked in water. Fruit should stay a rare treat, not a staple. Protein levels much above what wild grazing provides contribute to shell pyramiding over time.
Is pellet food enough for leopard geckos?
No. Leopard geckos are strict insectivores and will not eat plant based pellets built for bearded dragons or tortoises. They need live or canned feeder insects such as crickets, dubia roaches or Zoo Med Can O’ Crickets, ideally gut-loaded or dusted with calcium first.
Do aquatic turtles need more protein than land tortoises?
Yes, considerably more. Aquatic species like red-eared sliders eat animal protein in the wild, so foods like Zoo Med Aquatic Turtle Food run around 34 percent crude protein. Land tortoises need roughly a third of that, since their wild diet is almost entirely plant matter.
How long does reptile food last once opened?
Dry pellets stay fresh for a few months in a sealed bag kept cool and dry. Prepared gel diets last only three to five days refrigerated. Canned feeder insects should be refrigerated after opening and used within about a week.
What is a healthy calcium to phosphorus ratio for reptiles?
Most keepers aim for roughly two parts calcium to one part phosphorus across a reptile’s full diet, not necessarily every single meal. Base foods with added calcium make that ratio easier to hit without constant supplement dusting. A ratio running the other way, more phosphorus than calcium, is the main dietary driver of metabolic bone disease.
Which reptile food brand is best for gut-loading crickets?
Fluker’s High Calcium Cricket Diet is built specifically for that job, feeding crickets and mealworms before they become dinner. It works across most common feeder insects, not just one species. Breeders keep it on hand alongside a regular cricket keeper rather than as a standalone food.
The verdict
Zoo Med Natural Bearded Dragon Food is the strongest single pick here for anyone keeping an omnivorous lizard, needing no extra gut-loading and holding a workable calcium ratio straight from the bag. Tortoise keepers should skip it and reach for Mazuri Tortoise Diet instead, built around the fiber and low protein tortoises actually need. Anyone raising a strict insectivore like a leopard gecko gets more value from Zoo Med Can O’ Crickets paired with Fluker’s High Calcium Cricket Diet than from any single pelleted bag.
