Clownfish are one of the most distinctive and popular saltwater pet fish. These cute little marine creatures got a massive boost from the hit movie “Finding Nemo”. But they’ve always been popular with aquarium owners because of their hardy nature and vivid appearances. Also known as anemone fish, the various species make beautiful and fascinating marine pets. In this guide, we’ll look at everything you need to know about keeping pet clownfish.
1. There Are Different Types of Clownfish
When people think of clownfish their minds automatically see orange and white stripes. However, this is only one type of clownfish. The reality is that there are 28 species of different sizes and color schemes. Ocellaris clownfish remain the most popular variety and are the most similar to the movie character: Nemo. Others include the maroon clownfish and the very rare mucullochi. There is even a blue clownfish; however, its name is a misnomer. The stripes are a light blue color, while its body is orange.
2. A Clownfish Tank’s Should Mimic Nature
Clownfish live in anemone hosts in shallow lagoons in the wild. Trying to replicate their environment when they’re in captivity is crucial. We advise at least a 20-gallon tank for a single adult clownfish, although this may vary depending on the species. Get a longer aquarium rather than a deeper one because they like exploring their territory. Include plenty of marine plants and rocks for them to hide.
Owners should provide a two-inch gravel or sandy substrate. These fish only grow to about 3.5 inches, but you’ll still need a larger tank for two fish. We recommend adding anemones to the tank because of their natural symbiotic connection. This isn’t essential, but it is good for their fulfilment. Keep the tank in a relatively secluded area of your home. It should be out of direct sunlight and away from loud noises. Be aware that they may also jump out of the tank, so cover it properly.
3. Clownfish Need Specific Water Parameters
One of the most essential aspects of caring for any fish is getting the water parameters right. We’ve already mentioned that clownfish are relatively hardy compared to other saltwater species. However, this can change quickly if their water isn’t conditioned correctly. There should be a pH level of 8.1 to 8.4 for ocellaris clownfish. We’ll focus on them because they’re by far the most popular species.
There should also be a water hardness of 8 to 12 dGH. We recommend a sustained temperature of 77 to 80 degrees Fahrenheit in your saltwater tank. Use testing kits to check these parameters regularly. You’ll also need a good filtration system to keep the tank clean. A hydrometer will be necessary to test saline levels. Change 25 to 30 percent of the tank’s water each month to keep the aquarium healthy.
4. Clownfish Are Relaxed and Peaceful Pets
Another advantage of keeping clownfish is that they have relaxed and mellow personalities. This means that owners can pair them with some other species of fish. Typically, they live harmoniously alongside cardinalfish and gobies amongst others. “Finding Nemo” fans will also be happy to learn that blue tangs (Dory’s species) make great tankmates for them. It’s essential to have enough space in the tank; clownfish sometimes act territorially toward members of the same species.
Maroon clownfish have a reputation for being the most aggressive. They may attack smaller fish like percula clowns with fatal results. Be careful when mixing this variety with others because it can be an expensive mistake. Some owners successfully mix occelaris clownfish and percula clowns. There’s no guarantee this will work out, so be wary!
5. Clownfish Are an Omnivorous Species
Clownfish are an omnivorous species, which is good news for owners. It’s easy to find their food at local marine life stores. Experts recommend feeding them several times throughout the day. This is because the warm water triggers their metabolism, so they digest food very quickly. You can feed them regular pellets, but it’s good to supplement this diet with wholefoods. They love brine shrimp and some raw vegetables. Clownfish may eat algae too, but don’t expect them to clean their tank alone. Remember to remove uneaten food so that there’s no negative effect on the water parameters. Don’t overfeed clownfish because it can also cause obesity.
6. Clownfish Are Generally Healthy
Clownfish are robust fish if owners care for them properly. A clean and healthy tank will eliminate most issues. Remember, prevention is better than dealing with health problems. They may suffer from fin rot or bacterial infections if you don’t clean your aquarium efficiently. Poor water quality from algae blooms or leftover food is hazardous for all fish. Other health problems may include pop-eye or even parasites. To prevent health problems, quarantine new fish regardless of the species. Clownfish can live for between 10 and 15 years so they’re a long-term investment.
Brooklynea is a condition that disproportionately impacts clownfish. Some marine lovers even refer to it as clownfish disease. A thick mucus covers their gills and affects their breathing. It can be fatal without immediate attention so consult a vet if necessary. It’s essential to quarantine any clownfish suffering from this condition immediately. Wild clownfish are more susceptible to this than fish raised in captivity. Always buy marine life from licensed stores because this drastically reduces the risk. Every aquarium owner should keep a backup tank. This can be simpler than the main one. It will be useful for cleaning and quarantining purposes.
