Do Turtles Eat Goldfish? Vet-Reviewed Facts & Safety Guide

Updated on
Live food is an important part of a healthy pet turtle’s diet, both for omnivorous and carnivorous species. The answer is yes, feeder fish such as goldfish are among the best live food you can offer your aquatic turtle, which should be one of the primary live prey your turtle eats. Some great feeder fish you can provide for your turtle include guppies, smelt, bait minnows, as well as goldfish. But why is live prey so important? And how much of it should be fed to your pet turtle? In this article, we will answer those questions and more.
Benefits of Feeding Your Pet Turtle Goldfish
Live food is an important part of your turtle’s diet, and it provides a good source of animal-based proteins for your pet. Likewise, it can be rich in calcium, assuming your turtle eats the entire fish, bones included.
Furthermore, live food is great for your turtle’s quality of life, not just its nutritional benefits. Chasing live prey can be excellent mental stimulation and physical exercise for your turtle. For your turtle, the challenge of pursuing and catching their dinner can be highly satisfying, and it mimics how they would find their meals in the wild.
Due to the nutritional value and benefits to your pet’s quality of life, live prey (such as goldfish) are a great part of your turtle’s regular meals.
Safety Concerns of Feeding Goldfish to Your Pet Turtle
While feeder fish like goldfish are great for your turtle’s health, there are also risks to be aware of when feeding them to your pet. First, goldfish can carry parasites and bacteria, which may lead to infection if your turtle eats them. For this reason, you should never feed your turtle wild-caught fish.
Next, while live fish are suitable for your turtle, moderation is key. Oily fish, in particular, should be fed sparingly since they are high in fat. Too much fat may disrupt your turtle’s nutritional balance and lead to deficiencies. Similarly, if your turtle is fed an overabundance of fish, they may develop a thiamine deficiency.
Live goldfish can be fed safely to your turtle, but raw meat and frozen or freeze-dried fish should be avoided. Raw meat lacks a proper balance of calcium and phosphorus, which can significantly affect your turtle’s health. Likewise, frozen or freeze-dried fish do not have enough essential vitamins for your turtle.
What Other Live Food Can Your Pet Turtle Eat?
Besides goldfish and other fish, there are other live creatures that you can feed to your turtle. While feeder fish should still make up the bulk of life food that you provide, any of the creatures below can be fed to your turtle as well:
- Shellfish
- Insects (earthworms, mealworms, waxworms, etc.)
- Brine shrimp
- Snails
- Slugs
If you are considering rotating other live animals into your turtle’s regular diet, consult your vet before offering them to your pet. Dead animals should be removed from your turtle’s enclosure immediately since they can lead to disease.
How Much of Your Pet Turtle’s Diet Should Be Live Prey?
Knowing how much live prey is appropriate to feed your turtle can be difficult. Assuming that your pet turtle is omnivorous, their diet should consist of a combination of plant and animal material. Your turtle’s diet may change as they age, but for the typical adult omnivorous turtle, these are the proportions that you can expect to feed them:
- 50% or more of plant material
- 25% live animal protein
- 25% pellets
Goldfish should make up no more than 25% of your turtle’s diet. 25% may be a bit too high, as other live creatures should be fed to your turtle on occasion as well. Therefore, when you are feeding goldfish to your pet turtle, ensure that you are offering a proper amount of your pet’s other food.
How Do Turtles Eat Live Prey?
If you’ve ever looked closely at your turtle, you have likely noticed that they don’t have teeth. So, how are they eating live animal protein? Rather than using teeth to slice and bite through their meals, turtles have firm, sharp points on their mouths to cut through the meat. This is often referred to as their beak, which looks similar to a bird’s. Some turtles even have a hard, secondary palate along their upper jaw to help them crush their food.
Can Your Pet Turtle Eat Goldfish Crackers?
Even if your turtle may happily munch on a goldfish cracker when offered, that doesn’t mean that this snack should be fed to your pet. Salty snacks high in carbohydrates (such as goldfish crackers) are unhealthy for your turtle. As mentioned before, the main parts of your turtle’s diet should be plants, live animals, and pellets. There is no room in your turtle’s tummy for a cracker.
You don’t need to be concerned if your turtle manages to sneak a bite of a goldfish cracker, but it shouldn’t become a regular part of your pet’s diet.
Be Wary of Overfeeding Your Pet Turtle
Turtles are opportunistic feeders. This means that they will eat as long as food is available in front of them. Therefore, it is important that you closely monitor how much your turtle eats, as they may be prone to overeating if you are not careful. If your turtle overeats, they can develop health conditions such as hepatic lipidosis or fatty liver disease. This condition can lead to a lack of appetite as well as worrisome weight loss, so make sure that you are deliberate about how much food your turtle is given.
Can You House Your Pet Turtle and Your Pet Goldfish in the Same Enclosure?
Housing your turtle and goldfish in the same enclosure is a recipe for disaster. We’ve already established that your turtle sees goldfish as prey and will not hesitate to eat them. Therefore, you shouldn’t keep your pet turtle and fish in the same enclosure under any circumstances.
Final Thoughts
Goldfish are a suitable meal for a healthy turtle’s diet. They contain essential vitamins and nutrients and allow your turtle to catch their prey, thus providing your pet with mental and physical enrichment. Ensure you provide the proper portions when feeding goldfish or other live prey to your turtle. If your turtle’s diet is skewed out of proportion, your pet may face serious health consequences. If you are unsure of how much you should be feeding your turtle, consult your vet and devise a dietary plan together.
