Finding Nemo Fish Tank
Finding Nemo Fish – Nemo, Marlin and Coral
In Disney’s Finding Nemo, Nemo, Marlin (his dad) and Coral (his mom), are clownfish. To be more precise, they are Ocellaris Clownfish, which are also sometimes referred to as called False Percula clownfish. There are over 30 different types of clownfish found throughout Pacific tropical regions like Australia, Thailand and the Philippines.
With the popularity of this movie, many people became interested in setting up a Finding Nemo aquarium.
With a bit of guidance and education, setting up a Nemo aquarium is possible. If you are not up to the challenge of caring for a saltwater Nemo fish tank, you can instead set up a freshwater system and incorporate Finding Nemo aquarium decorations.
If you decide that setting up a Nemo tank is right for you, we carry all the aquarium supplies you will need to set up your tank and our knowledgeable staff is available to help anytime you have a question.
To keep a pair of clownfish, you will need an aquarium around 20 gallons or larger. Fortunately, we carry everything you need to put together your first marine aquarium system. Just choose one of our all-in-one systems, add saltwater, cycle the tank and acclimate your new fish to their home.
Dory, a Blue Tang, cannot join Nemo in an aquarium less than 125 gallons. If you want to keep Dory with Nemo and/or Marlin, you will need to purchase a large aquarium. Alternatively, you could place an aquarium decoration of Dory’s likeness in a smaller tank. Click here to learn more about Dory and how to care for Blue Tangs.
Many people want to recreate the saltwater aquarium seen in the dentist’s office in Finding Nemo. Unfortunately, the mix of livestock shown in the movie would not work well together, especially in a smaller tank. You could, however, keep some of the animals safely together in an aquarium around 30 gallons, like Gurgle (a Royal Gramma), Deb and her mirror image “Flo” (Damselfish, although some types can get a little aggressive) and Jacques ( a Cleaner Shrimp). There are also starfish suitable for aquarium life, but they generally don’t resemble Peach from Finding Nemo.

Below you’ll find a complete species profile of Ocellaris Clownfish that should help you make determine if you are up to the task of setting up a saltwater aquarium for Nemo:
Ocellaris Clownfish or False Percula Clownfish (Amphiprion ocellaris).
Indo-West Pacific: Eastern Indian Ocean including Andaman and Nicobar Islands, Thailand, Malaysia and Northwest Australia to Singapore, Indonesia and the Philippines; ranges north to Taiwan and the Ryukyu Islands (from fishbase.org). They are also widely bred in captivity and whenever possible we recommend buying captive bred instead of wild caught (so a real-life Marlin won’t have to come looking for his son inside your aquarium!).
Level of Care
The Ocellaris Clown is a medium maintenance fish. Ocellaris clownfish in general are considered a hardy saltwater fish.
They can be kept singly or as a pair. It is not recommended to keep more than two in a tank due to aggression issues, especially in smaller tanks. They may act semi-aggressively toward other fish, especially when new fish are added to the aquarium, during feeding time and/or during breeding. They are found to coexist with Heteractis magnifica, Stichodactyla mertensii, or S. gigantean anemones. Clownfish DO NOT require an anemone to survive and it is perfectly normal for tank raised and wild caught clownfish not to host in anemones inside home aquariums.
Keep water quality high (SG 1.020 - 1.025, pH 8.1 - 8.4, Temp. 72 - 78 F). Clownfish can live in fish only systems as well as reef aquariums.
The Amphiprion ocellaris grows up to 4 inches.
Minimum Tank Size
The False Ocellaris Clown prefers an aquarium at least 20 gallons in size with plenty of places to hide and swim.
The Amphiprion ocellaris is an omnivore and likes to eat variety of foods (meats and veggies). High quality flake and/or pellet foods along with a variety of frozen foods are excellent choices for clownfish. It is recommended to alternate feedings of different types of foods for optimum health benefits.
Clownfish are known to breed in captivity. All clownfish are males when they are born. As they grow, the dominant male will become a female and the next dominant male will become its mate. Any other clownfish that remain in their presence will remain males with a hierarchy being established among them. If the female is removed from the group or dies, the dominant male will change into a female and the next dominant male will become its mate. Once they are a female, they cannot change back into a male.
