If you have a pet turtle like I do, you might wonder how much food to give them. I see many turtle owners asking me, “Can I overfeed my turtle?” The truth might surprise you.
So, can you overfeed a turtle? Yes, you can absolutely overfeed a turtle. Turtles don’t know when to stop eating. They will keep eating even when they are full. This can make them sick and fat. Too much food can hurt your turtle’s health and make them live a shorter life.
In this article, I’m going to tell you everything about feeding your turtle the right amount. I’ll share what I learned from taking care of my own turtle. Keep reading if you want to keep your turtle healthy and happy.
How Much Do Turtles Actually Eat?
The amount your turtle should eat depends on a few things. Let me break this down for you in simple terms.

Age Matters A Lot
Baby turtles eat more often than adult turtles. I feed my baby turtle every day. Baby turtles are growing fast, so they need more food.
Adult turtles don’t need food every day. I feed my adult turtle every other day or every three days. This keeps them healthy.
Size of Your Turtle
Small turtles eat less food than big turtles. This makes sense, right? A tiny turtle can’t eat as much as a huge turtle.
Here’s what I do: I give my turtle food that’s about the size of their head. This is a good rule to follow.
What Type of Turtle You Have
Different turtles eat different amounts:
- Red-eared sliders eat a lot when they’re young
- Box turtles don’t eat as much
- Painted turtles eat medium amounts
I always check what type of turtle I have before deciding how much to feed them.
Signs You’re Overfeeding Your Turtle
I learned these signs the hard way when I first got my turtle. Watch out for these things:
Your Turtle Gets Fat
Yes, turtles can get fat! If your turtle’s legs and head look puffy, they might be eating too much. Their shell might also look too tight.
Leftover Food in the Tank
If there’s always food floating in your turtle’s tank, you’re giving them too much. Turtles should eat all their food in about 15 minutes.
Dirty Water All the Time
Too much food makes the water dirty fast. If you’re cleaning the tank every few days, you might be overfeeding.
Your Turtle Looks Lazy
Overfed turtles don’t swim or move much. They just sit around all day. A healthy turtle should be active and curious.
How Much Food Should You Give Your Turtle?
Let me share my feeding schedule that works great:

For Baby Turtles (Under 1 Year Old)
I feed baby turtles every single day. The amount should be about the size of their head. That’s not much food, but it’s perfect for them.
For Young Turtles (1-3 Years Old)
Young turtles get food every other day. I give them a bit more food than babies, but still about head-size portions.
For Adult Turtles (Over 3 Years Old)
Adult turtles only need food every 2-3 days. They can eat bigger portions, but not huge ones. I stick to the head-size rule.
What Happens When You Overfeed Your Turtle?
Overfeeding causes many problems. I’ve seen these issues in turtles that eat too much:
Health Problems
Liver Problems: Too much food hurts the turtle’s liver. This can make them very sick.
Kidney Issues: Overfeeding also damages kidneys. Turtles with kidney problems can die.
Shell Problems: Fat turtles can’t fit in their shells properly. Their shells might grow wrong.
Behavior Changes
Less Swimming: Overfed turtles don’t like to swim. Swimming becomes hard when they’re too heavy.
Breathing Problems: Fat turtles have trouble breathing. Their neck gets too thick.
Can’t Hide: Turtles need to pull their head into their shell for safety. Fat turtles can’t do this.
Shorter Life
Turtles that eat too much don’t live as long. Wild turtles can live 50+ years. Pet turtles that are overfed might only live 10-20 years.
The Right Way to Feed Your Turtle
Here’s my step-by-step feeding method:

Step 1: Choose the Right Food
I use high-quality turtle pellets as the main food. Good pellets have all the nutrients your turtle needs.
Step 2: Add Fresh Foods
I also give my turtle fresh foods like:
- Small pieces of fish
- Leafy greens
- Small insects (for meat-eating turtles)
Step 3: Use the 15-Minute Rule
I put the food in the tank and watch. If my turtle doesn’t eat everything in 15 minutes, I remove the leftover food.
Step 4: Stick to a Schedule
I feed my turtle at the same time each feeding day. Turtles like routines.
What About Treats?
Yes, you can give your turtle treats! But treats should be very small and not often.
Good treats include:
- Small pieces of strawberry
- Tiny bits of melon
- A single cricket
I only give treats once a week. Remember, treats are extra food on top of regular meals.
Common Feeding Mistakes I See
Let me tell you about mistakes that many turtle owners make:
Mistake 1: Feeding Every Day
Many people think turtles need food every day like dogs or cats. This isn’t true for adult turtles.
Mistake 2: Too Much Variety
Some owners give their turtle different food every day. This can upset their stomach. Stick to the same good foods.
Mistake 3: Human Food
Never give your turtle food meant for humans. Pizza, bread, and candy are very bad for turtles.
Mistake 4: Not Removing Old Food
Old food makes the water dirty and can make your turtle sick. Always remove uneaten food.
How to Tell if Your Turtle is Hungry
Hungry turtles act differently:
- They swim to you when you come near
- They follow your finger along the glass
- They look alert and active
- They stick their head up when they see you
But remember, just because your turtle acts hungry doesn’t mean they need food right away!
Special Feeding Tips for Different Turtle Types

Red-Eared Sliders
These turtles love to eat! They’ll beg for food even when full. Stick to your feeding schedule no matter how much they beg.
Box Turtles
Box turtles eat less than water turtles. They also like more plant foods than meat.
Painted Turtles
Painted turtles are good eaters but not as greedy as red-eared sliders. They’re easier to manage.
Creating a Feeding Schedule That Works
Here’s the feeding schedule I use:
Monday: Feed (if it’s feeding day) Tuesday: No food Wednesday: Feed (if it’s feeding day) Thursday: No food Friday: Feed (if it’s feeding day) Saturday: No food Sunday: Treat day (very small treat)
This schedule keeps my turtle healthy and happy.
What to Do if You’ve Been Overfeeding
Don’t worry if you’ve been overfeeding your turtle. You can fix this:
- Stop feeding every day – Switch to every other day or every third day
- Give smaller portions – Use the head-size rule
- Remove old food faster – Don’t let food sit in the tank
- Add more swimming space – Help your turtle exercise
- See a vet – If your turtle is very overweight, ask a vet for help
Signs of a Healthy Weight
A healthy turtle should:
- Be able to pull their head and legs into their shell
- Swim easily and smoothly
- Be active during the day
- Have clear, bright eyes
- Not have puffy legs or neck
Frequently Asked Questions
Can Box Turtles Be Overfed?
Yes! Box turtles can definitely be overfed. They actually need less food than water turtles. I feed my box turtle every 2-3 days with small portions.
Can Red-Eared Slider Turtles Be Overfed?
Red-eared sliders are the easiest turtles to overfeed because they always act hungry. Stick to a strict feeding schedule with these turtles.
Can Baby Turtles Be Overfed?
Even baby turtles can be overfed. Yes, they need food more often, but they still need the right amount. Baby turtle stomachs are tiny!
How Do I Know if My Turtle is Too Fat?
Look at your turtle from above. If their legs and head look puffy, or if they can’t pull into their shell, they might be overweight.
What if My Turtle Refuses to Eat?
If your turtle won’t eat for more than a week, take them to a vet. This could mean they’re sick.
Conclusion
Taking care of a turtle means being a responsible pet parent. Don’t overfeed your turtle just because they act hungry. Turtles in the wild don’t eat every day, and your pet turtle doesn’t need to either.
Remember these key points:
- Baby turtles eat daily, adults eat every 2-3 days
- Use the head-size rule for portions
- Remove uneaten food after 15 minutes
- Watch for signs of overfeeding
- Stick to a feeding schedule
I hope this guide helps you take better care of your turtle. A well-fed turtle is a happy turtle, and a happy turtle can be your friend for many, many years!
