The aquarium hobby introduces us to a mesmerizing world of tropical fish, each species boasting unique colors, shapes, and behaviors that captivate our attention. While any fish can add a touch of natural beauty to a home, certain species stand out as exceptional “pet” fish. But what exactly defines a fish as a “pet”? It’s more than just visual appeal; it’s about personality, interaction, and the bond you can form. A “pet” fish is one that earns a nickname – the Mr. Bubbles, the Finny McWhiskers of your aquatic world. These are the fish that transcend being mere decorations and become cherished members of the family, much like a dog or cat.
This list explores ten remarkable fish species that are not only visually stunning but also possess the personality and charm to become true pets. While this isn’t an exhaustive compilation, it features popular and widely loved fish that many aquarists agree are truly “name-worthy”.
10. Freshwater Angelfish (Pterophyllum scalare)
The Freshwater Angelfish is an icon in the aquarium world, instantly recognizable with its elegant, elongated fins and disc-shaped body. Often purchased as juveniles, barely larger than a coin, these fish can mature to an impressive size, reaching up to 6 inches in diameter with fins extending to over a foot in height. While a group of angelfish in a large community tank might blend into the background, a solitary angelfish or a pair in a smaller setup often develops a distinct personality that earns them a special place in their owner’s heart and, of course, a name.
Angelfish are known for their graceful movements and interactive nature. They often swim to the front of the tank to greet their keepers, exhibiting curiosity and even interacting with each other in playful ways. As members of the cichlid family, known for their intelligence and complex behaviors, Angelfish embody the qualities of a true aquatic pet.
9. Fancy Guppies (Poecilia sp.)
Fancy Guppies are another long-standing favorite in the aquarium hobby, gracing tanks for over a century. Selective breeding over generations has resulted in a dazzling array of fin shapes and vibrant color patterns. While a school of guppies is undeniably beautiful, keeping just a few allows their individual personalities to shine, making them more likely to be named and cherished.
Guppies are constantly active, adding life and movement to any aquarium. Their gregarious nature and bright colors are endearing to hobbyists of all levels. The vast variety of strains often produces uniquely colored individuals, making it easy to distinguish and recognize specific fish – a key factor in naming them. Their energetic swimming requires a balanced diet. High-quality flake food, supplemented with small pellets rich in fat, protein, and vitamins like Aqueon Tropical Flakes, helps maintain their vitality and vibrant colors.
8. Mollies (Poecilia sp.)
Closely related to guppies, Mollies are another excellent choice for beginner aquarists seeking pet fish. Black Mollies, in particular, were among the first fish many hobbyists ever kept. The males, with their striking sail-like dorsal fins, and the females, known for giving birth to live young that are miniature replicas of themselves, have cemented the Molly’s popularity over decades. Their offspring are relatively large for livebearers and can immediately consume finely crushed Aqueon Tropical Flake food after birth.
Mollies are active and social fish, interacting readily with each other and their human caretakers, further solidifying their “pet” status. Naturally herbivorous, their diet should include plant-based components. Aqueon Pro Herbivore pellets and Aqueon Algae Rounds cater to their dietary needs and ensure their well-being.
7. Tiger Barbs (Puntigrus tetrazona)
Tiger Barbs are small yet spirited fish that frequently capture the hearts of their owners. These energetic fish are often seen at the front of the aquarium glass, displaying a captivating mix of lively swimming and poised elegance. They strike a perfect balance between the hyperactive nature of danios and the calm demeanor of angelfish. If not for their preference for groups, which can make individual recognition challenging, they might rank even higher on this list.
It’s worth noting that Tiger Barbs can sometimes nip the fins of slower or more delicate fish. Therefore, careful consideration is needed when selecting tankmates. However, their engaging personalities and bold stripes make them fascinating and name-worthy additions to a suitable aquarium setup.
6. Oscars (Astronotus ocellatus)
Oscars, the second cichlid on our list, are renowned for their intelligence and popularity among aquarium enthusiasts. These fish are capable of learning simple tricks and exhibit problem-solving skills and behaviors that suggest a capacity for emotions. Oscars often enthusiastically greet their owners and may even seem to “sulk” when their caregivers are absent, demonstrating a level of interaction rarely seen in fish.
Their primary drawback as pets is their significant size. Oscars can grow to exceed 12 inches in length, requiring a minimum tank size of 75 gallons, with 125 gallons being even more ideal. Feeding Oscars feeder goldfish is a common but ill-advised practice. Not only is it expensive, but feeder goldfish can also introduce diseases and lack nutritional value for Oscars. A balanced diet of high-quality pellets and freeze-dried foods, such as Aqueon Cichlid Pellets and Aqueon Monster Fish Medley, is far more economical and beneficial for their health.
5. Ocellaris Clownfish (Amphiprion ocellaris)
The Ocellaris Clownfish, the sole marine representative on this list, is an instantly recognizable aquarium icon. Often simply called “Nemo” after the famous movie character, Clownfish have become the most popular saltwater fish in the hobby. Today, the majority are bred in captivity, and numerous color variations are available.
While saltwater aquariums require more specialized equipment and attention compared to freshwater setups, keeping clownfish is not overly complicated, especially with readily available resources and beginner-friendly guides. A small marine tank, like the Coralife Biocube, almost necessitates including a clownfish, particularly in households with young children. For those venturing into saltwater aquariums, resources are readily available to guide beginners.
4. Convict Cichlids (Amatitlania nigrofasciata)
Another cichlid making the list is the Convict Cichlid, a small but feisty fish. While we specifically mention Amatitlania nigrofasciata, any species from the Amatitlania genus originating from Central America would be suitable as a pet. Despite being a fraction of the size of an Oscar, Convict Cichlids possess the same bold personality and attitude of much larger fish.
They are fiercely territorial, confidently defending their space, even against their human keepers, using displays and nipping to deter perceived threats. Their engaging personality makes them entertaining to observe. Convict Cichlids breed readily, and watching them care for their offspring can be a fascinating experience. However, be prepared for the challenge of finding homes for the numerous fry. A diet of Aqueon Mini Cichlid Pellets is ideal for maintaining their health and vibrant colors.
3. Mbuna Cichlids (Various genus and species)
Mbuna, pronounced “mmm-boo-na,” are a diverse group of cichlids originating from Lake Malawi in eastern Africa. These cichlids exhibit a wide spectrum of colors and sizes, ranging from a few inches to around 8 inches in length. Their active swimming and captivating personalities make them excellent pet fish.
However, Mbuna cichlids are best kept in species-specific tanks or with other African cichlids. They require slightly harder and more alkaline water conditions than rainforest species and can be aggressively territorial, especially towards non-cichlid tankmates and even each other. In a Mbuna community, it’s often easy to identify the dominant male, who frequently becomes the one to earn a nickname and stand out as a distinct pet. As herbivores, Aqueon Pro Herbivore formula is a perfect dietary staple for Mbuna cichlids.
2. Fancy Goldfish (Carassias auratus)
Few fish are more deserving of a name than the classic goldfish. Whether won at a fair or purchased from a pet store, goldfish are often the first fish many people keep. They are attractive, relatively easy to care for, and possess an endearing personality. Similar to Oscars, goldfish can grow quite large, necessitating larger aquariums or outdoor ponds as they mature.
While a few juvenile goldfish can be kept in a 10-gallon tank temporarily, larger accommodations are essential for their long-term well-being. Beyond the common “Comet” variety, numerous fancy goldfish breeds have been selectively developed over centuries, showcasing unique body shapes and colors. These fancy goldfish are known for their interactive nature, often recognizing and engaging with their owners.
And #1. The Betta (Betta splendens)
No fish is more frequently named than the Betta, also known as the Siamese Fighting Fish. This is largely because Bettas are often kept individually in smaller tanks or desktop aquariums. Male Bettas are fiercely territorial, making it impossible to house multiple males together. They can even be aggressive towards females in many cases. Their solitary nature makes them ideal for individual setups, contributing to their “pet” status.
This unique behavioral trait has made the Betta the undisputed king of desktop aquariums and a popular pet for homes and offices. Many Bettas exhibit active personalities, eagerly swimming to the front of the tank for feeding time, especially when offered Aqueon Betta Food or Aqueon Betta Treats. While they can sometimes appear lethargic, resembling a sunken leaf, they are generally interactive and responsive. Although tropical fish, Bettas are tolerant of cooler water temperatures (down to around 70°F), but thrive in warmer water around 78-82°F. If room temperatures are cooler, an Aqueon Betta heater or Flat Heater can help maintain the ideal water temperature.
