How can you tell if your clownfish is happy and healthy? Unlike other pets, fish don’t show emotion. At least not that we can easily interpret. 

Then how do we know if our fish are happy and satisfied with the habitat we’ve created for them. That’s the real question.

I recently bought two baby clownfish. I made sure that I chose the healthiest clownfish in the group. How did I know which one was the healthiest clownfish? 

A healthy clownfish should eat when fed. It should have vibrant colors, breathe normally, swim actively, and have undamaged fins. Those factors should be great indicators of whether your clownfish is healthy or not. 

Here’s an in-depth breakdown of the indicators mentioned above.


Eating regularly

One of the best signs of telling whether your clownfish is healthy or not is observing their feeding habits. Healthy and happy clownfish will always try to eat as much as possible.

My clownfish are always begging for food. They are always excited when I am next to the tank. Or at least I like to think they are.

When a clownfish refuse to eat or do not eat regularly is a bad sign. They are not picky eaters, so you know something is wrong with them when they don’t eat.

Vibrant colors

One of the reasons people like to keep clownfish, besides the Pixar animated movie Finding Nemo, is their incredible coloration. When I saw a clownfish for the first time in my life, I knew that I had to keep them. 

They have vibrant and bright colors that really pop under proper lighting. You know that your clownfish is happy when it has vibrant and bright colors. Pale colors, on the other hand, are indicators of stress or disease.

Breathing normally

Fish, just like all other animals, need oxygen to live. Water is about 800 times denser than air, so fish had to develop efficient mechanisms to extract oxygen from the water.

Healthy clownfish should breathe normally. Heavy breathing indicates that your clownfish is stressed or sick. Check your water parameters to see if everything is on point. You should have enough movement on the water surface to allow gas exchange.

Swimming actively

A happy fish should swim actively, and it should not be afraid of the other fish in the tank. It’s normal for a fish to be shy and hide if it’s recently added to the aquarium.

When it comes to clownfish, most of these rules don’t apply. Clownfish are weird fish. 

They could swim vertically, sleep in odd positions, or just lie on the sand. Don’t worry if you see your clownfish acting like this. 

If they eat regularly, breathe normally, and have vibrant colors, they are definitely happy and healthy.

Undamaged fins

Happy clownfish should have healthy fins. Clownfish can be aggressive, and it’s very important to be careful when choosing tankmates. 

Two females will often fight to the death. Always start with two juveniles if you plan to keep a pair of clownfish. Never keep more than two clownfish because there is a big chance they will fight when they mature.

Final Thoughts

Clownfish are great pets to have, and if you provide them with the right conditions, they will live a long and happy life. Here are some tips on how to ensure your clownfish are living their best lives.

Keep your water crystal clear. High-quality water is the key to a happy clownfish. Keep stable water parameters, make regular water changes, and your fish will thrive in the tank.

Keep the temperature stable. Clownfish are tropical fish and need stable temperatures without significant daily fluctuations.

Feed them quality food. A diverse diet will strengthen their immunity and will make your clownfish healthier and, with that, happier.

Add corals to the tank. Create the best possible environment for your clownfish. Make them feel like they are home because they are. Add different types of corals, and later on, an anemone when your aquarium is more established. Your clowns will love it.

As you have seen, it’s not difficult to make clownfish happy. Just make sure that you provide them with the essential requirements. 

And your clownfish will reward you with their beautiful appearance and unusual behavior.
