Albino Rainbow Sharks 301: Best Care, Size, Tankmates & Food

Overview

The Rainbow Shark may be a tropical freshwater cyprinid that’s somewhat difficult to keep. it might be suitable for fish keepers who have a couple of years of experience and are looking to expand their aquarium.

They are popular for their territorial nature and bright vibrant red fins.

Originating from the nice and cozy rivers of Southeast Asia, they got the affectionate the common name of Rainbow Shark, because of their upright dorsal fin which provides them the looks of a shark.

You should expect your Rainbow Shark full-grown to six inches long and have a lifespan of 5-8 years.

If your intention is to keep these tropical sharks you must ensure your aquarium has lots of hiding places for them as this helps to decrease their territorial behavior.

Rainbow Shark Price

In terms of cost you must be looking to spend no over $3 per fish, and that they are readily available all year round.

Rainbow Sharks’ Appearance

They are mostly popular for their red fins, which is basically what gives them their name. Apart from being red, sometimes their fins may take on an orange hue as well.

The Rainbow Shark could be a dark gray fish with vibrant orange/red fins. Some also have a dark blue body, which is somewhat less common. They have an extended, flat stomach with a pointed snout and an upward dorsal fin. It’s this fin that provides them the looks of a shark.

It is a tiny fish that you ought to expect to get older up to around 6 inches when fully matured. It is impossible to spot their gender whilst they’re juveniles. You’ve got to wait until they’re sexually matured.

Rainbow Shark Male or Female

There are some color differences between males and females. For instance, males tend to have brighter orange or red fins than females do.

Males also have very thin gray lines on their tail fins, while the females do not have any thin lines.

Female rainbow sharks are also thicker and have more rounded bellies than males. It becomes apparent as the fish mature as there is primarily no distinction between the juvenile male and female rainbow sharks.

You will have to wait until the red tail fish are physically mature to differentiate between males and females.

Once they become sexually mature, females will have thicker bodies, and males will develop small black lines on the tail fin. Whilst males are going to be thinner, they are going to generally have brighter colorations.

The Albino Rainbow Shark or Albino Shark is a common variety of the Rainbow Shark.

Whilst the Albino Red Tail Shark maintains the orange/red fins, its body is white. It will grow to an identical size as a traditional and standard Rainbow Shark and matches a few of their features including being territorial.

Rainbow Shark Lifespan

The average lifespan of a rainbow shark is between four to six years, however, some of them have been known to live for as long as eight years or more.

That is longer than other aquarium fish like Bettas, which can only live for about two years. But, it is much less than goldfish, which may have a long lifespan of up to twenty years.

The Albino Rainbow Shark

There is an albino version of the rainbow shark which is popularly known as Albino Rainbow Shark. This fish has the same red fins as the rainbow shark possesses, however it has a white body rather than black or blue markings.

The body of an albino rainbow shark can take on a yellow or light pink hue as well. The beautiful and light-colored body contrasted with the brilliant fins it has gives the albino shark a very unique, yet highly sought after appearance.

General Behavior and Temperament

In the natural habitat, rainbow sharks are more passive and they do not really prey on other aquatic animals or fish. They are territorial fish. It can cause certain behavioral issues like aggression and dominance.

This generally happens as they grow up. As juveniles, these sharks are timid and can spend large periods of their time hiding. They are a kind of Labeo Sharks.

Are Rainbow Sharks bottom feeders? They are very active swimmers and have a tendency to spend most of their time dwelling at the bottom of the fish tank. Because of them being bottom-dwellers, they are referred to as aquarium cleaners as they can eat the growing algae on the bottom of the fish tank.

Make sure your aquarium has plenty of space and is long for your Rainbow Shark to swim on the same water level. Whilst they’re peaceful with fish that dwell in higher water levels, they’re known for fighting with bottom-dwelling fish, including their own species.

Some of the behavior can include chasing, biting, and head-and-tail butting.

You can plan to minimize this behavior by ensuring they’re placed in a comparatively large aquarium, with a low fish to water ratio. Also, you have to ensure they have plenty of hiding places, like tunnels, caves, and other hollowed décor.

Lastly, whilst they are not known for jumping, it is not unheard of. That is why you should make sure your lid is well fitted to prevent them from jumping out of your fish tank. When they are first placed in the aquarium then jumping generally occurs.

Rainbow Shark Care

There is a couple of stuff you have to consider when it involves caring for rainbow sharks. Overall they’re tough little guys and don’t require to be babied, but that’s assuming you’re taking care of their essential needs.

Below we highlight the most important areas that you simply got to concentrate on when it involves care for them. If you stick with these guidelines you’ll be on your way to ensuring that they live a cheerful and healthy life.

Habitat and Tank Requirements

As mentioned in the overview section of this article, Freshwater Rainbow Sharks are tropical shark fish and it originated from Thailand.

They are very active swimmers, therefore the adults shouldn’t be kept in aquariums that are smaller than 50 gallons. The aquarium should even have many horizontal spaces. If your aquarium is too short in length it can encourage them to become more aggressive and territorial.

If you have a plan on keeping so many Rainbow Sharks then it is advisable to use at least a six-foot-long, 125-gallon fish tank (however we do not recommend keeping more than one of this type of shark per aquarium; we will discuss more on this later).

Because of their territorial nature, you should have to make sure your aquarium has plenty of hiding places for them. Think rocks, caves, and treated driftwood.

Plants and dense vegetation also work. Plants may be used to keep the Rainbow Sharks distracted so it can reduce conflict and also it helps prevent algae.

As for substrate, they’re the best suited to sand, as this is often what’s found in their native Thai rivers. Be cautious if you plan to use gravel because the sharp edges can cut them. If you intend to use gravel make sure the quality of the gravel is very fine.

Lastly, you have to ensure your aquarium lid is fitted well, they can jump!

Water Details

Maintaining the proper pH levels is extremely important if you want to have the most effective for your fish. Rainbow sharks do best in water that’s between 6.5 and 7.5 pH levels.

Before putting them in a brand new tank environment, prepare and ready your water and permit it to cycle for at least 14 days so that it has time to stabilize.

Do Rainbow Sharks need a heater? This is a common question that arises in our mind while keeping this shark in tank water. The answer is yes. Use an aquarium heater to maintain your aquarium water temperature to between 72 and 79 degrees Fahrenheit.

Upon bringing the rainbow shark to your home, place it immediately into your fish tank using a net.

Doing this can help to prevent shock and give them the best possible environment in which it will thrive.

How Big Do Rainbow Sharks get?

Rainbow shark max size at full maturity is usually no longer than 6 inches long. There are some that have grown to be as long as 8 inches long, but those are an exception.

This size holds true for normal rainbow sharks as well as the same with the albino varieties. Both males and females tend to be about a similar size long.

Tank Conditions

You must keep it within the following parameters: pH level 6.5-7.5, 75°F to 81°F, and a water hardness of 5 to 11 DH.

Always try to keep the pH level stable with Rainbow Sharks. Sudden changes in the pH level may be harmful and can cause them to become very much aggressive than usual.

The Lighting of the aquarium should be kept at a medium level, and maintain the water movement moderate.

Compatibility and Rainbow Sharks Tank Mates

What can live with a rainbow shark? Are rainbow sharks aggressive?

Let me preface this category by stating if you’re trying to find a calm community fish, the Rainbow Shark is not the perfect fish for you.

While they are going to get along with a lot of other freshwater fish / freshwater pet sharks, they’re very much territorial and this will be overwhelming for more shy species, like Marbled Otocinclus catfish and hatchet fish.

As mentioned above in the aquarium and habitat section, they always prefer to take possession of an area of the aquarium; normally the rocks and small caves.

We have sympathy with any kind of fish which stumbles upon the territory of a Rainbow Shark! They chase the intruders away and can be extremely aggressive. Because of their aggression, you require to be careful while choosing the freshwater sharks for the tank as tank mates.

As a normal rule, they are not aggressive towards species that don’t seem like Rainbow Sharks. As they dwell at the bottom of the aquarium, try to avoid other bottom-dwelling fish species such as catfish and cichlids. Also, you have to avoid any similar-looking fish, i.e., any other semi-aggressive freshwater fish like Purple Glofish, Tetra Glofish, Bala Sharks, and Red Tail Sharks.

While choosing the tank mates for your Rainbow Sharks, always try to find those fish that dwell in the upper and middle levels of the aquarium

You may also want to pick fish that can defend themselves and have a strong but calm personality. Species such as barbs, Gouramis, Rainbowfish, and Danios are all compatible with Rainbow Sharks.

At last, you may use a tiny compatibility trick: the Rainbow Shark should be the final fish placed in the aquarium. This can prevent it from trying to claim the whole aquarium as its own and can reduce territory issues.

Keeping Rainbow Sharks

How many rainbow sharks can live together?

As a simple rule, it is recommended that you just keep one Rainbow Shark in a fish tank at any time. Red Tail Sharks can also be added to this general rule.

They do not tolerate living with their own kind as the Royal Gramma does.

In the wild scenario, they simply lead a solitary lifestyle, and also they are so much territorial. In a normal fish tank generally, there is not enough room and the bigger Rainbow Shark shall chase the smaller kind of Rainbow Sharks relentlessly until it kills them.

Will rainbow sharks kill other fish? With their increasing age this territorial nature develops. Therefore if you get a pair of juvenile Rainbow Sharks they might very well start out getting along, however, their relationship may decline rapidly as the rainbow shark fully grown or becomes mature.

Follow the following guidelines if you insist on keeping more than one Rainbow Shark.

• You have to keep a group of them (5 or more). This way the dominant Red Fin Shark has several fish to chase.

• Never keep only two Rainbow Sharks.

• If you wish to put more than one Rainbow Shark make sure that each shark has at least a meter of diversified territory.

Rainbow Shark Diet and Feeding Requirements

What do rainbow sharks eat?

Rainbow Shark Food: They are mostly Omnivores that eat a lot of algae, larvae, and both meat and plants.

In the wild environment, they normally consume decaying plants, insect, algae, larvae, and little chunks of meat they find in the river like Zooplankton

In an aquarium, they will also eat any algae that naturally form at the bottom of your tank. Also, you may provide them algae in a wafer, tablet, or flake form if there isn’t sufficient space inside your aquarium for them to dine on.

They are not just fussy eaters. Also, they consume most other things; providing it sinks to the bottom of the fish tank!

This is very good news if you intend to keep the Rainbow Sharks in an aquarium. They can eat frozen food, flake food, pellets, live food, and vegetables with no complaints.

Your aim should be to keep their diet varied and feed them different food sources, similar to what they would eat in the wild environment. For example algae (wafers or tablets), insect larvae, zooplankton, and crustaceans (frozen or live).

To maintain their diet varied you may also offer them lots of vegetables such as lettuce, spinach, peas, and zucchini; this will make their immune system very strong.

Will Rainbow Shark eat shrimp? If you want to ensure their orange/red color is a vibrant shade, you should give regular meals of frozen and live meat to them; brine shrimp and frozen bloodworms will be also fine.

It is also more important for juvenile Rainbow Sharks. If you want this juvenile Shark to grow big with vibrant colors, it is important to ensure their diet is varied and never overly limited. The lack of variation may result in stunted growth and poor color expression.

As for their feeding regime, you must intend to spread rainbow shark food range out over 2-3 sessions per day. The actual length of the feeding duration should be around 5 minutes.

If any amount of food is left after this feeding time, you’re overfeeding them and it will impact your nitrogen cycle.

Why is my rainbow shark not eating?

If you give the Rainbow Sharks floating food, they can’t eat as they live in the middle or down part of the aquarium water. However, if you give them sinking food in the fish tank they can easily eat the food.

Rainbow Sharks Breeding

In the wild environment, they intend to mate from October to November. It is when they also achieve sexual maturity. But the exact month of mating can be impacted by changing seasons. It is dependent on the temperature and length of the day.

Note: Assume that if the fish is smaller than 4 inches in length, they are not sexually mature yet.

Rainbow Shark Eggs: Rainbow Sharks reproduce through the egg-laying process. The female Rainbow Shark will lay eggs. After that, the male will then fertilize them by spraying the eggs together with their milt.

From this moment the eggs will hatch within a week. When this tropical shark starts to hatch from eggs, they are not much bigger than mere specks. From that moment, they begin to grow rapidly.

Unfortunately, It is extremely challenging breeding Rainbow Sharks in an aquarium and we are yet to listen to any success stories.

Again, this is more than similar because of their territorial and aggressive nature in confined settings.

The majority of Rainbow Sharks which you find out with an intention to purchase will be bred in commercial fish farms based in Southeast Asia.
