Clownfish Care

The Clownfish is probably the most popular saltwater fish species today and one of the reasons that many people want to get into the saltwater hobby. The Disney movie Finding Nemo probably has a lot to do with the incredible popularity of the clownfish. Clownfish have a somewhat unique way of swimming. They don't swim like other fish, they waddle and it kind of reminds you of a happy dog when it comes up to greet you. The orange, white and black coloration on the Ocellaris is strikingly beautiful. The Ocellaris Clown is often confused with the True Percula Clownfish because the two species look very similar. The Ocellaris has very thin black bands around the white stripes whereas the True Percula has much wider black bands on the white stripes. They will take almost every type of marine food available and can be very easy to keep.

Many believe that you can't keep a Clownfish without their host anemone. This is not true. You can keep them without their host anemone and many have reported success with breeding them even without having their host anemone present. Because many breeders are having success breeding them, tank raised clowns are readily available. In fact, you are generally much better off buying a tank raised clownfish than a wild one because the tank raised fish tend to have better survival rates and should acclimate more quickly. Tank raised clowns usually cost slightly more than the wild ones but if they adapt better and live longer, it's worth it.

The host anemones that are found in their natural environment of the clownfish can be difficult to care for in captivity and are not recommended for the saltwater novice. Very high output aquarium lighting such as metal halides is often required.

Clownfish Care Facts

Scientific Name : Amphiprion ocellaris

Other Common Names : Clownfish, Anemone Fish, Orange Anemone Fish, Nemo

Clownfish Care Level : Easy, very hardy and good for saltwater beginners, especially the tank raised clowns which should acclimate easier than their wild caught counterparts. Also, keeping them with anemones is not necessary. Only keep anemones if you have the proper aquarium lighting.

Size : 3 - 4 inches (10 cm)

pH : 8 - 8.4

Temperature : 75°F - 80°F (24°C - 27°C)

Specific Gravity : 1.020 - 1.024

Clownfish Lifespan : 3 - 6 years generally, but see comment below from Dudley who has a pair of percula clowns that has been alive for 27 years!

Origin / Habitat : Indo-Pacific to Oceania

Clownfish Temperament / Behavior : Usually they are a very peaceful marine fish. Avoid mixing the various clown species though. If you have a mix of different clown species in your tank, they will fight. If you have a host anemone in the aquarium with them, they will defend it. It usually works out best if you have only one or a pair of clowns in your tank.

Clownfish Breeding : They have been bred in captivity and it is usually better to buy a tank raised fish because they will adapt better in the home aquarium. More information on breeding clownfish.

Aquarium Size : 30 gallon minimum

Clownfish Tank Mates : Avoid keeping them in an aquarium with Lionfish, Snappers, Groupers, Triggers, Eels or any other predatory fish large enough to eat them. Keep only one clown species in your aquarium. Do not mix the various clown species.

Disease : Saltwater Fish Disease - Diagnose, Symptoms and Treatment

Diet / Foods : Omnivore - provide a varied diet with live food, frozen food and they will also accept flake food.

Tank Region : All over

Clownfish Gender : All are males when they are born. As they mature and start to pair off the dominant one will change into a female. The female is usually larger than the male and will be the primary defender of their territory.

Clownfish Tips

From: Dudley Hartz
Percula Clownfish can live much longer than once thought. Mine are the oldest I know of and they are 27 years old and have lived the last 24 years with no anemone. The less animals you keep in the tank, the better their chances of survival.

From: Stefan
Clownfish are friendly and have an amazing personality. I would recommend them to anyone new to marine fishkeeping as they are interesting and relatively hardy.

From: Dan
My clownfish is 17 years old or so. I bought it in 1989. I even had a tomatoe clown that tortured it for 6 years, until the trigger fish killed the tomatoe. How many times do you think my clownfish has curled his body in the current? Amazing and captivating.

From: Carlos
I have had mine for 3 years and it lives in a 10 gallon tank. It has been eating flakes but twice a week I feed it frozen mysis. Good for beginners and an awesome fish. A+

From: Jacob
I have had my ocellaris for about a year now. He is still my favorite fish. Very hardy and entertaining fish. It loves to be hand fed and gets very excited when he sees me with food. Great personality and very peaceful. I would recommend them for anyone that has space for a peaceful smaller sized fish.

From: Angelo
I have a pair of ocellaris clownfish. The female is going on 7 years (and it was purchased from Petco) and the male will be 4 in 3 months.

From: V.P.
I'm a beginner to marine aquarium keeping. I have a 15 gallon live rock-only aquarium. I just bought a clownfish and a bicolor pseudochromis. I was so relieved to see that they get along very well. They don't bother each other at all. I want to get two or three more small fishes. What kinds get along well with clowns?
Several species should go well with clownfish, but you're already at your limit in a 15 gallon tank. This is very small volume of water to keep stable and adding more fish into this setup will only make it that much more difficult to keep stable and safe for the fish.

From: Rebekah
I have a 55 gallon FOWLR tank with 70 lbs of rock. Currently in the tank are: 1 ocellaris clownfish, 1 green clown goby, 2 yellow-tailed blue damsels, 2 pajama cardinals, and 1 firefish. The clownfish is the newest addition and it has not eaten since I brought it home about 3-4 days ago. I feed frozen brine shrimp and a dry marine pellet. It will pick at small clumps of algae in the tank but then spit it out. I've read that they will eat just about anything. Is mine just being picky? Any suggestions for the picky eater?
It could be several things contributing to your clown's lack of appetite. Is it getting bullied at all by any of the other fish at feeding time? Especially watch the damsels, they can be quite territorial. These are all fairly small species in your tank, maybe try a flake food. Perhaps the food being presented (pellet) is too big? Although, not going after defrosted brine shrimp is troubling since fish usually go crazy for that. If he doesn't start to eat soon you may need to quarantine this fish and watch for any signs of disease.
