In the wild, clownfish live at the bottom of the ocean, where corals are present. They also associate with the lagoons. The warm tropical waters are the home of clownfish.
Clownfish have a relatively good life span. In the wild, they can live around 6 to 10 years.
How Long Do Clownfish Live In A Tank Or Captivity?
In captivity, clownfish have around 3 to 5 years of life span. But the life span of the fish varies with several factors.
|Clownfish Type||Lifespan||Care level|
|Common Clownfish||3-5 years||Easy|
|Maroon clownfish||3-7 years||Easy|
|black clownfish||3-5 years||Easy|
|Cinnamon Clownfish||17 years or more||Easy|
|Tomato Clownfish||6-8 years||Easy|
|Clarkii Clownfish||12-14 years||Easy|
|Pink Skunk Clownfish||20-21 years||Easy|
|Saddleback Clownfish||12 years or more||Moderate/ Intermidiate|
|Orange Storm Clownfish||8-10 years||Easy|
Factors Affecting clownfish life span
- Tank space
- Food availability
- Water condition
- Water Temperature
Additionally, in the wild, clownfish have a symbiotic relationship with certain sea Anemones. It means both organisms have benefits when they live together.
Clownfish eat the leftovers food particles from fish that on sea anemone. The leftover fragment includes isopods, copepods, and zooplankton.
But in captivity, they cannot maintain this relationship.
Further, the aquarium environment does not perfectly match the same as their natural environment. It causes to reduces the life span of clownfish when you rear them in captivity.
The lifespan of aquarium bread clownfish and wild clownfish
Clownfish have a symbiotic relationship with sea anemones in the wild. They associate with certain sea anemones to find food.
Anemones also have benefited from clownfish. The Clownfish can clean algae leftovers from sea anemones’ bodies. Further, they provide better water circulation to the sea anemone while swimming.
Clownfish’s body is cover with mucus, and it helps them to protect from sea anemones.
In captivity, Clownfish cannot maintain this symbiotic relationship. Clownfish have to live in a limited space and satisfy by provided food. Thus, the life span of clownfish in captivity is relatively shorter than in wild.
Generally, they live around 3 to 5 years in captivity. In their natural habitat, clownfish live around 6 to 10years.
What can reduce the lifespan of clownfish?
In captivity, clownfish live the environment that fish hobbyists provide for them. Most of the time, the aquarist cannot provide ideal conditions to clownfish. It reduces the life span of clownfish in captivity.
The following mentioned reasons highly affect the clownfish lifespan.
Water quality is a critical factor that determines the lifespan of any fish. You should provide ideal water quality parameters to keep healthy fish.
The water quality parameters are;
The temperature of water: 73- 84 Fahrenheit is ideal. The water temperature should keep stable. If not, it directly affects the fish.
Water pH level: Water pH is a critical thing. Clownfish need slightly alkaline water conditions. The pH should be between 8.1-8.4. If you do not consider the pH level, Clownfish may have a bad influence because of it.
The salinity of water: Clownfish prefer to live saline water which has 1.023-1.025 specific gravity. If aquarists are unable to maintain this salinity level, it affects the fish’s osmoregulation process. If the fish lose their ion balance, they will die soon.
You should maintain the salinity of the water at a stable level. Water evaporation and water replacement can change the salinity level of the tank. When water evaporates, the salinity level will increase.
If you add new freshwater to replace the existing water, it will reduce the salinity level of the water.
Both processes directly affect the water salinity level and also fish health.
Ammonia, Nitrites, Nitrates: These compounds are highly toxic to every fish, including clownfish. These substances’ concentrations should be at zero. If it exceeds ten ppm, marine organisms will badly affect.
These compounds produce due to fish hobbyists’ bad practices. These are;
Excess food contains high protein levels. Deterioration of fish food generates ammonia, nitrate, and nitrites.
Lack Of Water Changes: Some aquarists do not exchange tank water for months. Then fish fecal matter can accumulate in the tank, and those compounds can spoil and deteriorate the water.
Water Filtration System: The filter system should be enough to filter the water in the tank. If you install the wrong filter or filter is not functioning well, fish fecal matter, excess food can accumulate in the tank.
That debris can produce nitrogenous waste, which highly toxic to the clownfish.
Overcrowded Tank: Overcrowded tank generates more waste within a short time. Further, fish may fight with tank mates for territory.
Additionally, the oxygen supply will not be enough for fish. These facts can cause to reduce the life span of your clownfish.
Non-Compatible Tank Mates
Clownfish is a peaceful creature. But if you add clownfish with a different variety of the same genus, they will show aggressive behaviors.
The Tomato clown, Maroon clown, or any other clownfish are unable to live together. If you mixed those varieties, all the clownfish might stress. Then their life span will reduce.
Note: To reduce aggressive behaviors of clownfish,add six, seven fish together.
Clownfish are hardy eaters. In the natural environment, they have a symbiotic relationship with sea anemone. Because of the omnivorous behavior, they can rely on any food type.
But in captivity, if they cannot have enough food or quality foods, it causes to reduce their life span.
Size Of The Tank
Clownfish can live in 10 gallons tank. But if you try to put them in a tiny tank or fish ball, they will die due to the stress.
Further, the salinity and ammonia level may suddenly fluctuate in the small tanks. Clownfish are very sensitive to these parameters. Thus, if they fluctuate regularly, clownfish may have a harmful impact.
It is a common parasite found in marine fish. The scientific name of the parasite is Brooklynella hostilis, and they attack the gills of the fish.
If you do not give proper treatments immediately, clownfish may die within a few hours or days.
- Breathing difficulties
- Fish become lethargic
- Refuse to eat
- Fade the body colors
- Thick whitish mucus covers the body
Dip bath in freshwater gives temporary relief to fish. If not, you can kill the parasite using the following methods.
- Chloroquine treatment for 14 days, the dose is 15 mg/l
- Daily dip infected fish in a formalin solution for 15 minutes. The formalin concentration should be 150 ppm.
Maintain water salinity of quarantine tank at 1.018 specific gravity. It assists the clownfish in balancing the electrolytes lost due to skin and gill damage.
This disease also common in saltwater Jawfish, Angelfish, Wrasses, and seahorses.
Are Clownfish Suitable For Beginners?
Yes, generally, Clownfish is a hardy fish. Further, their space requirement is relatively low than other fish. Thus, I can recommend clownfish to rear for the beginner.
As a beginner, you should gain good knowledge before adding them to your aquarium. You must have good background knowledge about clownfish,
- Water quality requirement
- Minimum space requirement
- Suitable tankmates
If you can reach the above factors properly, Clownfish will live a long time with you.
Can Clownfish Live In A Pond?
Yes, Clownfish can live in a saltwater pond if the following parameters ideally match their preferred level.
- Salinity: 1.023 -1.025 specific gravity
- Temperature :
- pH: 8.1-8.4
- Ammonia, Nitrates, Nitrite level : 0 ppm
In the pond, they can live freely more than a small tank or aquarium. But you should provide enough food to clownfish.
Further, it would be best if you took precautions to protect them from predators, such as snakes, birds, and domestic animals.
You cannot rear saltwater clownfish in a freshwater pond because water salinity is a significant factor that helps clownfish regulate their osmosis pressure.
Aquarists rear sea anemones in their saltwater ponds. If you can establish them in your pond, it gives a natural feel to your clownfish.
How Long Can Clownfish Live In Freshwater?
The marine fish and freshwater fish’s biology is different. Marine water fish cannot do their osmoregulation process in freshwater. Additionally, freshwater fish cannot maintain osmotic balance in saltwater.
Hence, clownfish cannot spend in freshwater for a long time. If you allow them to live one-two hours in fresh water, they will immediately die. They cannot survive an extended period in freshwater.
Clownfish or “Nimo” is a fantastic creature that adds extra value to your saltwater tank. They consider as hardy fish. Thus, Clownfish is recommended for beginners. But if you do not maintain water quality parameters at an optimum level, the clown fish’s life span will reduce.
