List of the long-living aquarium fish

The life expectancy of the vast majority of aquarium fish is short, ranging from one and a half to three years on average. Some species, on the other hand, live much longer and please their owners, saving them from having to constantly acquire new residents or breading juvenile fish on their own. You can learn about some long-lived fish species by reading on.

Goldfish champion with Chinese ancestors

List of the long-living aquarium fish

Not long ago, it appeared that modern exotic species would eventually supplant goldfish in aquarists’ minds. However, demand for these close relatives of the common carp, which were bred by Chinese breeders a millennium and a half ago and brought to Russia in the seventeenth century, is rising once more. Especially because a goldfish with the appropriate care will become a long-term family member.

Golden-red beauties with a veiled tail live for 15-20 years, and with proper feeding and optimal conditions, they can live for up to 30 years. Goldfish come in a variety of colors and sizes. The veiltail goldfish, on the other hand, became a famous Pushkin fairy tale character and one of the most popular decorative aquarium fish.

A goldfish must be fed the right food, no more than twice a day, and not overfed in order to live as long as possible. Overfeeding goldfish is simple: they are unusually voracious, as are all members of the genus Carp.

A goldfish requires clean, nitrate-free water at a temperature of 18-20°C, as well as a fairly large container—for a pair (male and female), an aquarium with a volume of 100 liters or more is required.

It’s also worth noting that finding good neighbors for slow, non-aggressive, clean goldfish is difficult. Some eat them, while others freeze in the cold water, and others make the area uninhabitable for goldfish.

As a result, for a species aquarium, a pair of goldfish or several females and a male is the best option.

Red-tailed black shark

List of the long-living aquarium fish

We recommend paying attention to the black shark if you plan to fill a large aquarium with long-lived fish. The shape and placement of the fins on these powerful, beautiful fish resemble that of a shark.

They can reach a length of 50 cm. They compete with fish that live in the same layer of water as them, the middle layer. They defend their ” own ” territory from other black sharks(labeos), so a large area, delineated with stones, ceramics, and large driftwood, will be required for the joint care of several representatives of the species.

Black labeos are active during the day, but they dislike bright light, so the aquarium should be lit softly and evenly.

The mainstay of a black shark’s diet is vegetable food (salads, vegetables), which should be supplemented with dry food, as well as a fresh or frozen animal protein food.

Black labeos can live for up to 8-10 years if properly cared for.

Panaque nigrolineatus (pleco)

List of the long-living aquarium fish

These catfish from the Loricaria family are notable for their vibrant color, unique fin shape, and unusual head-to-body proportions. The heat-loving fish with pronounced territorial behavior dislike cool water and do not get along with other catfish species, but they make good neighbors for cichlids-predators who live on the upper floors. The panaque’s body is reliably protected by bone plates, so the latter will be unable to harm it.

Because black-line panaques can grow up to 30 cm in length, at least 200 liters of water is required for a comfortable stay. When designing the aquarium, consider the possibility of creating a shelter for the catfish, which should be large enough to prevent the panaque from becoming entangled in it.

King pleco, like all native catfish, requires cellulose to survive. You can solve this problem by putting a stump in the aquarium, which the catfish will happily chew through. Add vegetables and spirulina tablets to his diet to make it more interesting.

If the environmental conditions are favorable and the feed is balanced and appropriate, striped big-headed catfish can live for up to ten years.

In most cases, not even professionals breed black-striped plecos in captivity; instead, they are delivered to aquarium farms from their natural habitats.

Metynnis argenteus

List of the long-living aquarium fish

If you’re going to order a large aquarium for a restaurant, entertainment center, or holiday salon, make sure the inhabitants will look good in a festive setting.

In the expertly created artificial lighting, the metynnis’ scales flash iridescent silver, creating a festive atmosphere and lifting the mood.

These fish are unpretentious and peaceful, and a small swarm will fit comfortably in a 300-liter aquarium or larger.

Metynnis can grow up to 15 cm in length (and nearly the same height) and delight their owners for ten years with their “shiny appearance.”

Livingston’s cichlid


These members of the cichlid family are notable not only for their stunning appearance but also for their unique behavior. Males can grow up to 25 cm in length, while females are smaller.

As is typical of cichlids, the males are aggressive. They will fight each other in the aquarium. Females are peaceful and calm, and they get along with other aquarium fish of similar size. At the same time, both males and females prefer to eat smaller fish, which should be considered when deciding on the species composition.

Nimbochromis livingstonii catches “small things” by posing as if dead and waiting for the prey to approach. Observing a “hunt from ambush” is incredibly fascinating.

Livingston’s cichlid can live up to ten years in captivity if kept in good conditions.

Piaractus brachypomus (paku)

List of the long-living aquarium fish

The omnivorous piranhas of the genus Paku, unlike the predatory members of the family, prefer a vegetarian diet but can eat small gaping fish.

The herbivorous piranha can grow up to 60 cm in captivity, requiring an aquarium with a volume of 1000-1500 liters for a swarm of 4-5 specimens. The piranhas’ normal existence depends on the pack, and they feel much safer together.

In general, these vicious, voracious, and fearless predators’ relatives are fearful. Paku panics when the light is turned on suddenly, when the glass is accidentally shattered, and when there are sudden movements near the aquarium. As a result, an artificial pond, where the shoal will behave more calmly and the fish can live up to 12-15 years, will be the best option for their care.

Clown loach

List of the long-living aquarium fish

You can communicate with fighting clowns for up to 15 years if you populate a large aquarium with mobile, very bright, and beautiful fighting clowns. And communicate in the truest sense of the word—the mustachioed pets express their gratitude with a characteristic snort.

Because the fish can grow up to 20 cm in length and live in swarms in captivity, they require a large aquarium: at least 400 liters per swarm of 3-5 animals. Take care of the artificial pool’s ventilation, cleanliness, and the consistency of parameters such as lighting, temperature, acidity, and hardness of the water, as well as the presence of numerous shelters where the animals can hide from prying eyes.

Banded cichlid

List of the long-living aquarium fish

Banded cichlid lives in pairs, and multiple pairs can only be kept in a very large aquarium divided into separate zones. Other aquariums are actively patrolled by the fish, who actively defend their territory.

Females can form false “family” pairs in the absence of males, in which one of the fish assumes the “duties” of the male to protect the territory without changing the genus. These fish are omnivorous, light-loving, elegant, and regally attractive. They can live up to 15-18 years in good conditions.
