Behavior of Clownfish
This fish is not a good swimmer at all because of the rounded structure of their caudal fin. They are not good at swimming, and they are very slow-movers as well. They are always in need of hiding places and food.
They remain peaceful throughout, and in the aquarium, they prefer to stay at higher levels. Most of them prefer to choose a place that has a low level of current in the aquarium.
Young species of Clownfish stay in a safe zone in the bottom until they are fully grown up. They are very particular about this place, and they don’t eat from any other places.
Lifespan of Clownfish
It lives approximately for 6 years, but it can live much longer (8-10 years) if you provide proper care to this fish.
Take a look at its diet, tank set up, and water parameters, which will help you to provide a longer life to them.
Diet of Clownfish
It is an omnivorous fish that lives on a diverse diet, which makes them popular instantly. You can feed any store-bought fish food (flakes or pellets) to your cute buddy.
In the wild, they are used to live on meaty foods – they readily eat small crustaceans, fish eggs, copepods, larvae, anemone tentacles, and so on.
You can try to replicate that in your aquarium by feeding the fish with chopped Brine Shrimps and Mysis. The store-bought food will supply the algae protein to the fish. As it is an omnivorous species, veggie and meaty food both are needed, and you have to balance it smartly.
Food quantity and Feeding Frequency
As this fish is small, drop such a quantity that it can consume in 3 minutes. Do not overfeed that fish, which may be dangerous for them.
Now, moving on to feeding frequency, feed the adults twice a day and juveniles trice or four times a day for their better health.
Choose an area where the water flow is very slow so that the Clownfish do not have any difficulty at the time of eating to fetch the food.
Tank Requirements of Clownfish
Now learn the tank requirements of this fish to provide a healthy home just like nature to them:
You need to get a minimum of 50-gallon tank for a Clownfish. A single fish can stay comfortably in a 20-gallon tank too, but if you want to keep a few pairs, you will need larger tanks, and in case you have planned to set a community tank with anemones, much larger tank will be required.
You can use any substrate, but sand will be the best option to replicate their natural habitat. Experts often said that a substrate-free tank would also be alright for this fish, but if it’s a community tank, the substrate may be mandatory for the tank mates. So choose accordingly!
Using rocks, live rocks, reefs, and fake reefs will be very pleasing for this fish, and it will be an aesthetic delight for the viewers too. Don’t forget to make hiding places for this fish. Also, beware that the swimming place for the fish remains sufficient even after placing all these decors.
An excellent quality filter, along with a protein skimmer, is required for this fish. Actually, a stable environment and good quality water are mandatory, and filtration will enable exactly these.
If it is a fish only tank, you will hardly need intense lighting for your fish. Again if you are keeping anemones, strong lights like metal halides will be required for their growth. If you are keeping only the Clownfish, any decent LED lights will be alright. In general, it does not have any specific lighting requirements.
Water Type for Clownfish
This fish is a bit sensitive to its water requirements, so be sure to check the water type before putting this fish.
Temperature, pH Level and Gravity
74-79°F (23.3-26.1°C) will be the ideal temperature for Clownfish with a pH of 7.8 – 8.4. Along with this, 1.023-1.025 SG gravity is acceptably good for this fish. Do check these parameters every week.
Just like any other fish, it will be necessary to remove the excess food particles or fish wastes to reduce the level of nitrite/nitrate/ammonia. You are free to use algae scrapers to clean up the algae, but any types of chemical use are harmful here.
There are different water changing guidelines for fish only and reef tanks. Check the following:
Fish only tank
15% water change twice a week is needed if it’s a small tank of a 40-gallon and you cannot skip this, in case you want this fish to stay longer. For smaller tanks, replace 5% water each week, and for a 90-gallon tank, a 20-30% water change in a month will be alright.
If you have 100-gallon or larger tanks, 20-30% water change after 6 weeks is acceptable. Also, it is required to replace the filters after a specific time.
5% water change each week for the small tanks of 40-gallon, 15% water change twice a week for the mid-sized (90-gallon) tanks, and 10% water change twice a week for larger tanks of 100-gallon and up are mandatory.

So, if you are planning to set a community tank with this, you will get various options like:

Clownfish and Sea Anemones
As they are slow swimmers, they are seen to stick to the anemones for safety in the wild! Yes, Anemones which are avoided by most of the marine creatures for safety reason. Clownfish and Anemones (a few species of both) are found in a symbiotic relationship in nature – they help each other.
Territorial Clownfish supplies nutrients to anemones by fighting back the dangerous species. At the same time, by producing mucus and becoming resistant to toxins, they can stay safe from the stinging and poisonous tentacles of anemones. Anemones protect this fish from the current from rocks or corals. They stay safe from predators, too, due to this. But it is hard to see in the aquarium.
Apart from the compatible tank mates, you can keep a few types of anemones to stay with this fish peacefully, but you probably miss the chemistry between them that you can see in nature.

Breeding of Clownfish
Percula Clownfish is seen to breed successfully in captivity, and you will have to set the temperature at 83°F to allow them to spawn. The wooing continues for 5 days, and at this stage, you can see the fish in different poses.
If you put Clownfish with Anemone, you will find the eggs are laid under the cleaned rocks near anemone.
Near about 50-500 eggs are produced each month, which hatch after 8 days. Right after hatching, they start swimming slowly at the bottom level of the aquarium for 15 days, and gradually they find a suitable home in anemones.
As sex detection of the fish is a bit difficult, breeding becomes more difficult, but it is not that impossible.
Common Diseases of Clownfish
Aquarium bred Clownfish are very hardy, but the wild-caught ones are less hardy as they have some immunity issues from the beginning. If you are planning to get one, go for a captive-bred one.
Marine Ich, Fin Rot, and Dropsy are the commonest diseases of this species, and you can look for the following signs in the fish to detect these diseases:
- Disintegrating fins
- Edge of the fins reddened
- Cysts in gills, fins, and whole body
- Breathing issues
- Pale skin
- Lack of appetite
It’s not hard to cure the cute Clownfish of these diseases simply by maintaining water parameters and by applying parasite remedy.
Discoloration and lack of appetite can occur due to stress too in this fish, and you need to observe for the abnormalities to understand these. In case you find out any sign of illness in the fish, it’s highly recommended to get an expert’s guidance without taking advice from Google.
