Feeding Frequency by Age
Feeding needs change significantly as reptiles age. Select your species and life stage for a species-specific feeding schedule.
Feeding frequency
Daily
Portion guidance
15–20 minutes of fresh greens — remove uneaten food after
Diet notes
High-fiber leafy greens only. No fruit, no protein. Calcium dust every feeding.
Key foods
Dandelion greens, broadleaf plantain, endive, collard greens
How feeding needs change with age
Hatchlings — growth phase
Young reptiles are growing rapidly and need consistent nutrition. For carnivore-leaning species like aquatic turtles, protein supports tissue and shell growth. For herbivores like tortoises, high calcium and fiber intake during the first two years directly determines shell quality for life.
Juveniles — transition phase
Diet composition shifts during this period. Aquatic turtles become progressively more herbivorous as they grow. Tortoises continue on leafy greens but tolerate slightly more variety. Feeding every other day (rather than daily) is appropriate for most species in this stage.
Adults — maintenance phase
Overfeeding is the most common husbandry mistake with adult reptiles. Reducing frequency prevents obesity, kidney stress, and shell pyramiding. Adults spend more time thermoregulating and less time feeding — this is normal behavior.
Frequently asked questions
My tortoise isn't eating — is that normal?
Reduced appetite is normal before, during, and after brumation. It's also common after moving to a new enclosure, during illness, or when temperatures drop. If a tortoise hasn't eaten in more than 2–3 weeks outside of brumation, consult a reptile vet.
Should I feed my turtle in or out of the water?
Aquatic turtles (red-eared sliders, painted turtles, etc.) should almost always be fed in water — they have fixed tongues and require water to swallow. Feeding in water also reduces mess in the main enclosure if you use a separate feeding container.
Do tortoises need supplements every feeding?
Hatchlings and juveniles benefit from calcium supplementation at every feeding. Adults can scale back to 2–3 times per week. Multivitamin supplementation 1x per week is generally sufficient for all ages.
