By

There’s something intriguing and captivating about sharks, and when you can have one in your own home aquarium? Of course you’d want to add this unique species to your tank. Unfortunately, keeping a small shark at home isn’t as easy as it might seem. Before you bring home a shark, take some time to learn about the pros and cons of having a shark and which breeds make the best small sharks for home aquarium life.

The pros and cons of small sharks for fish tanks

Sharks often require more care than your other aquarium creatures. Sharks can need specialized diets, and they have to be fed at precise times to accommodate their dietary needs. Some sharks may prey on the other fish in your aquarium, so choosing fish that can coexist with your shark can become a balancing act. Sharks can live for as many as 25 to 35 years, which makes them long-term choices.

If you’re thinking about adding sharks to your aquarium, then you’ll need to carefully research the species that you’re considering getting. Many sharks require significant space, so you might need a tank that’s 55 gallons or larger.

With careful research and an understanding of shark care, you can successfully add a small shark to your tank. Some sharks even feed on algae, adding balance to your aquarium environment. Sharks are beautiful and entertaining, and you’ll have the opportunity to observe shark behavior without visiting an aquarium. Owning a shark can be a unique experience, but you’ll need to weigh the pros and cons when deciding if it’s right for you.

The best small sharks for home aquarium settings

Part of the challenge of succeeding with a small shark in your fish tank is that many species grow up to be large. Starting with the wrong shark means that pet could quickly outgrow your aquarium and keep on growing! You might find yourself buying a larger tank, and then a larger tank, and then … you get the idea.

Certain small saltwater sharks are suitable for home aquarium environments:

  • The bamboo shark will need a large aquarium with plenty of room to swim. This breed of shark does get hungry, so pair it only with other fish that won’t make a tempting meal. This shark breed is nocturnal and uses its fins to walk across the floor of your tank.
  • The epaulette is a highly popular pet shark. This bottom-feeder moves quickly through the water, though it usually retreats to sheltered places, like those in between coral. It mainly eats shrimp and goes a few weeks between meals.
  • The smaller wobbegong shark species stays smaller, suitable for aquarium living. This unusual shark spends most of its time resting on the bottom of the tank, and it eats only every three to four days.

You also have plenty of small freshwater sharks to choose from:

  • The rainbow shark is a bottom dweller that likes to hide in rocks and plants. It’s active during the daytime and features brilliant coloring.
  • The silver shark, also known as the bala shark, lives well in a community setting with larger fish. These sharks grow up to one foot long and often swim as a group.
  • The harlequin shark thrives in aquariums where there’s plenty of algae and bacteria, which they feed on. They’re highly aggressive and require moderate care.

These sharks are all popular options for home aquariums, but it’s important to choose the species that’s right for your setup and goals.

Caring for your shark

These small sharks for fish tanks require more care than your typical fish species do. Specific care needs depend on the species of shark that you buy, but most sharks will benefit from a long, generously sized tank that gives them plenty of space to swim and explore.

In addition to investing in a large tank, plan to purchase a strong filtration system to accommodate the increased waste that sharks produce. You will also need to carefully monitor the water levels in the tank to maintain an appropriate environment for all your aquatic creatures.

Tank decorations aren’t only for good looks — they can matter to sharks. Many shark breeds prefer to hide in dense plants or coral, so you’ll need to provide an environment that’s conducive to your shark’s instincts and resembles their natural habitat.

Feeding your shark can be somewhat time-intensive. You may need to source specialty food, like shrimp, and you’ll need to plan feedings for times that accommodate your shark’s feeding schedule and dietary needs. Some sharks eat only once or twice a week, while others require more frequent feedings.

Successfully keeping a shark

If you think it’s time to add a shark to your aquarium, the more research you do in advance, the better. With thorough research, you can understand the unique traits and needs of the shark species that you’re considering. This can help you make the right choice for your tank.

What you need to know about sugar gliders before you get an exotic pet
Follow these steps to set your sugar glider up for success
Sugar glider clings to their owner's thumb

Choosing a small pet involves almost as much deliberation as selecting a breed of dog. While there are a lot of factors to take into account, a sugar glider might turn out to be the perfect fit with their curious personality, attachment to your family, and fondness for pockets.

Like any exotic pet, gliders require expert care plus some dedicated research to choose the right breeder or pet store. But with the right prep, your new mammal will fit in perfectly and bond with the whole family. Keep reading to find out if sugar gliders are good pets.
What are sugar gliders?
Unlike most little pets, sugar gliders aren't rodents but marsupials. This gives you a few distinct advantages, as they behave differently from hamsters, guinea pigs, or gerbils. For starters, these are highly social creatures and they will bond with every member of the family and even other pets in the house. Because gliders don't smell like the animals your cats and dogs like to chase — rats, gophers, and bunnies, to name a few — many bigger pets can get along with your new friend. You'll need to introduce them carefully, but they can form lifelong attachments to each other.

Add rainbowfish to your tank – these beauties will brighten up any aquarium
There are a few things you need to know before you get a rainbowfish
A colorful rainbowfish swims in front of plants in an aquarium

You might know of rainbowfish from the beloved children's book, but these are real animals that you can keep in your own home. As the name suggests, this group of swimmers is well regarded for being beautiful to behold. Many also get along nicely with other fish and can be handled by beginners. This is what you need to know before bringing home a rainbowfish.
What are rainbow fish?
It's a bit of a catch-all term because there are at least 50 species that all fall under the rainbowfish umbrella. Some work better as pets than others, and you'll probably be looking at boesemani rainbowfish, turquoise rainbowfish, featherfin rainbowfish, or red neon rainbowfish. If you're adding to an existing tank, research carefully to ensure you only get ones that will make friends with your current animals.
What conditions do they need to live in?
These are all freshwater fish, but their exact temperature and pH balance needs vary depending on which species you bring home. You can use your existing tank specs to narrow it down or do the opposite — pick the prettiest fish and then build your ecosystem around it. One thing to note right away is that you shouldn't keep males together and no rainbowfish wants to live on its own because they like to school. Consider keeping a group of six females if you want to prevent expansion.

Why should you add them to your tank?
Here are four excellent reasons to keep rainbowfish as pets.
They look beautiful
You can find just about any gradient you want in a rainbowfish. Some incorporate many colors, more like a traditional rainbow, while others skew toward blue, such as the turquoise rainbowfish, or red, such as the aptly named red rainbowfish.
They get along with other fish
While you want them to have friends of their own species, they'll also do great with others. Female rainbowfish can sometimes live with female bettas if you want to create a color explosion. Otherwise consider catfish, gouramis, and loaches as tank mates.
They're good beginner fish
The care level of most rainbowfish sits at about the same as a neon tetra (in fact, they can live together). Make sure your tank stays clean and that you change and test the water frequently, but they don't have any specialty needs.
They live a long time
Many tank dwellers have short life spans, and rainbowfish won't be any different if not properly cared for. However, boesemani rainbowfish, in the right environment, regularly make it to 5 years and sometimes even t10 years!

Looking to add corydoras to your aquarium? Here’s what you need to know first
Read this before bringing home a cory catfish to add to your tank

One thing you might not know about aquariums until you get one: Every tank needs a janitor, which may wind up just being you. When you first dive into this hobby, it can take a while to realize how much maintenance is really involved — don't think that the filter will do all the work. But if you want a little a help in that department, you can add a catfish to the fray. If you don't have a ton of experience with these bottom feeders, we recommend one of the corydoras since they're generally best for beginners.

What are corydoras?
This is a type of catfish, but there are actually more than 170 species to choose from. These are a well-known group of swimmers who get their name from their barbels, which look a bit like whiskers. While you'll find dozens of options in the pet store, you will likely narrow it down quickly based on the size of your tank, temperature, habitat you've chosen, and the other fish that they'll live with eventually.
Are corydoras friendly?
Yes, corydoras are sweet and gentle fish. They particularly like spending time together, but get along with many others as well. In some cases, you should not buy just one as they'll get lonely. Instead grab a pair of the same type and watch them become best friends. You'll often see them as bottom feeders, well, at the base of the tank, but cory cats also come up to the surface for air or food from time to time.
