Can gerbils eat fish? The answer is complicated. It depends on the type of gerbil, its age, and how often it eats fish. Fish is a high-protein food, which is good for young gerbils because they grow quickly and need the extra protein to maintain their weight.
Older pets can eat a little less fish due to lower energy needs or a decreased appetite. Some elderly pet owners may even want to feed their pet only vegetables and grains instead of meat altogether as part of an aging diet plan designed by a veterinarian.
1. Best Types of Fish For Gerbils To Eat:
Having a pet gerbil doesn’t mean you can feed it anything you want. You need to make sure your rodent friend has nutritious foods and has a balanced diet. We suggest feeding your gerbils with these types of fish:
- Herring
- Mackerel
- Salmon
- Sardines
They are all good choices for gerbils because they are high in protein and low on saturated fats. It’s also not difficult to find them at pet shops or grocery stores that sell frozen fish.
2. Types of Fish That Are Bad For Gerbils To Eat:
Don’t feed your gerbils with these types of fish:
- Tuna
- Herring
- Sole
- Swordfish
You should never feed your gerbils with the types of fish that have high levels of mercury.

These fishes can harm your pet’s health and might cause some serious problems. If you’re not sure about a certain type of fish, it’s always best to ask your veterinarian for advice.
3. Can A Gerbil Eat Frozen Fish?
Yes, gerbils can eat frozen fish. It’s best to feed your pet either fresh or previously frozen fish at room temperature. However, if you’re in a hurry and your gerbil needs to eat fish now, then we suggest thawing the food first before feeding it to your furry friend.
Just like humans, rodents need a balanced diet that includes fresh and nutritious foods. Feeding your pet with healthy types of fish is one way to make sure that your little friend stays healthy.
4. Can Gerbils Eat Canned Fish?
Gerbils should not be fed with canned fish since the food has high levels of sodium, which isn’t good for your pet’s health. As we’ve mentioned earlier, it’s important to provide your gerbil with a balanced diet that includes fresh and healthy foods.

A nutritious diet is one of the best ways to keep your furry friend healthy and happy. Make sure to include fish in your pet’s diet and ask your veterinarian for advice.
5. Can A Gerbil Eat Raw Fish?
This is a controversial topic on whether to feed gerbils with raw fish, cooked or frozen (after thawing). Some gerbil owners suggest giving raw codfish to their pets because it’s low in fat and high in protein.
This type of fish is also rich in vitamins and minerals, including Omega-3 fatty acids, which are beneficial for your gerbil’s health.
On the other hand, some pet experts say that raw fish poses a health risk to gerbils because it can contain harmful bacteria, such as Salmonella and Listeria monocytogenes, that can make your gerbil sick.
So, it’s up to you whether you want to give your gerbil raw fish or not. Just remember to always consult with your veterinarian before making any changes to your pet’s diet.
6. Is Cooked Fish Good For Gerbil’s Health?
Cooked fish is another good source of protein that your pet can eat. You should cook the types of frozen fish that are low in fat before feeding them to your gerbils. Once you thaw out the frozen fish, give it to your furry friends immediately because bacteria will grow quickly.
As for cooked herring, it’s safe to give your pet because all the potentially harmful bacteria from the raw fish will be killed during the cooking process.
7. At Which Age Gerbils Can Eat Fish?
Young gerbils, which are less than three months old, can eat fish as part of their daily dietary needs. However, they shouldn’t eat more than 2-3% of their weight per day.
That means if you have a young and healthy gerbil that weighs only 100 grams (which is the average size for this type of rodent), it can eat up to 2-3 grams of fish per day.

Older gerbils, which are three months old or older, should not eat more than 1 gram of fish per day due to their reduced energy needs.
So, the answer to the question “Can gerbils eat fish?” is both yes and no. It depends on your gerbil’s age and weight, as well as the type of fish you are feeding it. Consult with your veterinarian to create the best diet plan for your furry friend.
8. Pros & Cons In Gerbils Eating Fish:
There are both pros and cons in giving fish to your gerbils as part of their daily diet.
On the pro side, fish is a good source of protein and it’s low in fat. It also contains a wide range of vitamins and minerals that are beneficial for your gerbil’s health.
On the con side, fish contains high levels of mercury that can damage your pet’s health and cause serious problems.
So, we suggest you talk to your veterinarian first before giving any form of fish to your gerbil. By doing so, you are ensuring that it has a balanced diet with all the needed nutrients for a healthy life.
9. Other Meet Well For Gerbils:
The best sources of proteins for your gerbil’s diet are lean meats such as beef, lamb, and chicken. However, you shouldn’t give these to your pet in large amounts because they’re not appropriate for its dietary needs.
You can feed your gerbils with cooked or raw beef and lamb, which are low in fat and rich in beneficial nutrients.

Chicken is another good source of protein that’s relatively low in fat, but it contains high levels of phosphorus, calcium, and iron – elements that are not ideal for this type of rodent.
Gerbils should also eat small amounts of cooked eggs, cottage cheese, and yogurt daily. These dairy products are rich in calcium, protein, and other essential nutrients that your furry friend needs for a healthy life.
10. Other Food That Is Best For Gerbils:
In addition to the food listed above, other types of food are good for your gerbil’s health.
Carrots, apples, and other vegetables and fruits are great sources of vitamins, minerals, and antioxidants that your pet needs for a healthy life. You can give them to your furry friends in either raw or cooked form.
Gerbils also need to drink clean and fresh water every day. This is a critical element of your pet’s diet because it will help digest the food you give it.
