Fish isn’t essential to cats’ healthy diets, but it can make for a fun and tasty treat!

Fish
Goldfish are omnivorous creatures, meaning they feed off of algae, insects, vegetables and fish eggs naturally found in their environment. While it might be tempting to feed your Goldfish some leftover cat food instead, doing so could do irreparable damage to its health; cat food often contains salt, spices and additives which could wreak havoc with digestive systems while feeding your Goldfish predominantly cat food can also provide excess protein that’s unnecessary to its wellbeing.
Goldfish require a diet that mimics their natural habitat as closely as possible for optimal health. While diet is crucial to their wellbeing, holistic care also includes clean water, an appropriate tank size and companions as well as regular health checks to maintain an overall positive experience for all involved.
Vegetables
Goldfish are omnivorous animals and thrive when fed a diet rich in both plants and protein sources, such as those found in cat food. A diet high in animal proteins such as those found in cat food may strain their digestive system and lead to other health complications.
Vegetables such as carrots, cauliflower, spinach and broccoli contain essential vitamins and nutrients that can support their overall wellbeing. You can feed this bounty to your goldfish by dropping slices into their tank or cutting it up and feeding it individually.
Pumpkins provide goldfish with plenty of essential nutrition. Packed full of vitamin C, beta-carotene, potassium and manganese – you can feed a piece or drop an entire pumpkin into their tank as an additional treat for them to nibble at as they swim by!
Watermelons provide goldfish with plenty of vitamins and minerals, so offering bite-sized pieces every few days should ensure there are no incidents with choking.
Shrimp
Goldfish are omnivores; while most commonly seen as only being plant eaters, their wild diet includes animal foods like insects and eggs from other animals. Because goldfish tend to feed at random without realizing when to stop, offering varied food items will ensure their diet remains balanced and healthy.
Shrimp can provide an excellent source of protein for goldfish as an occasional treat, provided it has been properly cooked to destroy any bacteria present and without using spices which could pose health threats to them.
Feed your goldfish other foods that contain beta-carotene such as cucumbers and raspberries; melons have vitamin A and C while their rinds offer even more nutrition.
Cat Food
Goldfish are popular aquarium fish that can also make great house pets, making them great family entertainment and great additions to any household aquarium. Goldfish are known to be active and fun fish which make great playmates for children and can easily be fed by hand, making them ideal for beginners looking for something simple yet exciting to keep at home. You can feed them flakes or pellets specially tailored for them that contain essential nutrients, fats, and vitamins for their overall wellbeing.
Your goldfish need nutrition too, and bloodworms, brine shrimp or glassworms make an easy and convenient snack that provides it.
While a few bites of cat food will likely not cause harm to your fish, it is wise to choose those specifically made for goldfish. Other foods, like onions, scallions and raisins that contain human proteins could potentially cause anemia by attacking red blood cells in their body and leading to lethargy and kidney failure over time.
