We humans enjoy variety in our diets and it’s natural to wonder, do fish get tired of the same food just like we do? 

When I won my first goldfish Moby at the fair many years ago, I knew nothing about fishkeeping. One piece of advice I was given was to make sure I fed a variety of foods to keep him healthy.

That advice has stayed with me and Moby lived to the ripe old age of 15, so I’ve stuck with it ever since.

If you are struggling to get your fish to eat, read on until the end where I share a ‘magic ingredient’ that will get even the pickiest of fish to eat!

Do Fish Get Bored Of The Same Food? Signs To Look Out For

Based on my own experiences, I do believe that some fish may get fed up with the same foods day after day, I mean it’s hard to say for sure as they can’t talk to us, but there are signs you can watch out for.

Over the years I’ve had fish that were very picky as to what they’d eat, while others were gluttons who would eat anything and everything!!

A clear sign that fish may be getting bored of the same food is when they start to lose interest in it.

If you notice your fish have stopped eating their usual food, spit it back out, or only occasionally nibble on it, it may be time to look at alternatives and add some variety to their menu.

Having uneaten rotting food at the bottom of your tank isn’t great for keeping your tank clean and the water parameters in check either.

Why It’s Important To Feed Fish A Variety Of Food

Providing fish with a variety of food is essential for their overall health and well-being.

Fish that are not receiving the proper nutrition may exhibit lethargy, lack of interest in their surroundings, and may even become more susceptible to illness.

A varied and balanced diet ensures your fish get the right mix of nutrients, which allows them to grow and maintain good health.

A healthy immune system will prevent diseases and infections in your fish, such as:

Feed Your Fish Good Quality Fish Food

One thing that I cannot emphasize enough is the importance of providing good quality fish food.

I always look for high-quality fish food with real fish, shrimp, or vegetables listed as the main ingredients.

Cheap fish food tends to be full of crap that will make your fish feel like crap.

Feed Your Fish The Right Foods

healthy fish food alternatives

When I first started in the aquarium hobby, I thought that all fish ate the same type of food….flakes.

I quickly learned that different fish species have different dietary requirements.

A good quality species-specific flake or pellet food is a great place to start, and you can then offer other supplementary foods based on your fish’s dietary needs.

Carnivorous Fish

Carnivores, such as bettas, should be fed a wide and varied diet of protein-based foods such as:

  • Blood worms
  • Daphnia
  • Frozen brine shrimp
  • Muscles
  • Other fresh or frozen fish (cod, prawns, tilapia etc.)
  • Tubifex Worms

Herbivorous Fish

Herbivorous fish are vegetarian so need things such as:

  • Algae wafers
  • Fruits (as a treat)
  • Veggies (spinach, shelled peas, zucchini, etc.)

Omnivorous Fish

Omnivorous fish will eat both meat and veggie-based foods, so you should offer a balance of the above.

You don’t have to limit your fish to just fish food, you can really spoil your fish if you want to and whip up some home-cooked gourmet food for them.

I’ve done 3 quick and easy recipes with step-by-step instructions, that your fish will love in my What Can You Feed Fish Instead Of Fish Food article.

Can Fish Miss A Day Of Food?

I see many people panicking if they run out of food and can’t get any for a day or 2. 

Don’t worry most fish can easily manage a couple of days without food and it won’t harm them.

In fact, it can be beneficial to give their digestive system a rest.

Magic Ingredient!

Do you have a fish that is soooo picky that it turns its nose up at everything you try to feed to it….?

If so, I highly recommend you try adding garlic – yes garlic!

It’s a great appetite stimulant for fish, but before you go and chuck a clove into the tank, read the best way to feed garlic to fish so that you can do it safely.
