Buyers’ Guide

 

What do Bettas Need from their Fish Tank? 

Bettas have brilliant colors and look beautiful in an aquarium but they require care and special attention in order to thrive and live a healthy life. 

They are tropical fish originally so if you live in a colder region, you might need to regulate the temperature of the water in your fish tank. It’s important that you get a fish tank that has a built-in heater or can accommodate a separate heater being mounted onto it. 

Bettas are also very aggressive fish. If you’re going to have a Betta in a community tank with other fish, you have to make sure that there is ample room in the tank for all the fish to swim around freely. If your Betta gets stressed or agitated due to overcrowding, it might start picking fights with other tank members and harming them and itself. 

Bettas need light in order to grow and it stimulates energetic movements in them so be sure to get a fish tank that has a built-in LED lighting system or one that can accommodate a separate one. LED light mimics natural sunlight and provides your Betta with the seemingly natural stimulus they need in order to grow. 

What are some Basic Facts I should know about Betta Fish? 

Some facts that may help you in your fish-keeping journey with Bettas are listed below: 

Firstly, Bettas are unique from other fish by the fact that they have an organ known as the labyrinth. This unique organ allows them to breathe air from the surface of the water. This is the reason why you’ll normally find your Betta floating at the top of your aquarium near the surface of the water. 

Also, Bettas are carnivorous top-feeders. This means that they like feeding near the top of the surface of the water and they need a meaty diet in order to grow and survive. 

Bettas that are found in the wild usually have a dull coloration but they have now been bred selectively in captivity in order to produce the brightly-colored Bettas we’ve come to know now. Not only for their colors, a lot of Bettas are bred in captivity to produce different shapes of tails as well. Some of the tails commonly produced that are sold to fish-keepers are: 

  • Veil Tail
  • Cromb Tail
  • Crown Tail
  • Half Moon
  • Rose Tail 
  • Round Tail

How can I ensure Fast Growth in my Betta Fish Tank? 

There are several aspects that can ensure fast growth of your Bettas. Getting an appropriate fish tank is only half the job. 

If you’ve gotten an appropriately-sized fish tank, your Betta will have enough room to swim around. We recommend that you get aquatic plants, decorations and ornaments to put inside the tank so your Betta has things to move around, play and hide in. Bettas are energetic creatures and need things to do in order to be happy and healthy. 

Bettas are tropical fish that require light so make sure you have a light fixture on your fish tank that provides them with an ample amount of light. Bettas normally require about 12 hours of light each day. Make sure to turn the light off each day. Having a light on 24/7 can cause extreme levels of stress in your fish.

Lastly, you can try getting Betta food that has a focus on growth. There are different curated Betta food products available in the market that offer different things. You might want to invest in one that has ingredients that promise increased growth rates in your Bettas.

Why are Bigger Tanks always better than Smaller Tanks for a Betta? 

There are several reasons why investing in a large tank can be worthwhile.

As mentioned above, Bettas are energetic fish that love swimming around. If you have a large tank, your Bettas will have ample room to move around and play. 

Not only this, if in the future, you plan on expanding and getting more fish, you won’t have to invest in a larger aquarium because you’ll already have ample space in your current fish tank to accommodate an increase in your fish count. 

Bigger tanks also don’t have to be cleaned too often, especially if you have a small number of fish occupying that fish tank. This is because the waste products are extremely diluted in the large body of water. There is ample oxygen in it and the relative ammonia levels stay low for a long time before the tank has to be cleaned.

Frequently Asked Questions (FAQs)

 

Does a Betta Fish grow Relative to the size of the Fish Tank it’s living in? 

This is a common myth among novice fish-keepers. We must stress that that is all it is: a myth. You must research how big your Betta fish can grow and get a fish tank accordingly that will be able to accommodate it once it is fully-grown.  

If you get a 1-gallon tank for a Betta fish that will eventually grow to be over 3 inches. You’ll probably face catastrophic consequences and will have to get a bigger tank if you want to save your Betta.

Having a small tank that is unable to house your Betta can result in physical deformities, stunted growth, heightened stress levels and even death. 

Can a Fish Tank be too big for a Betta? 

In short, no. 

A fish tank can never be too big for a Betta. They love all the extra space they get to swim around in. However, a fish tank can be too big for you. 

While there is no harm in getting a large fish tank for your Betta, the bigger ones can get quite expensive so you need to look out for how much you can afford to spend on an aquarium.

Also, you have to keep in mind how much space you have in your home and get a fish tank of the appropriate size.

Can I use a Bowl or a Vase for my Bettas instead of investing in an Aquarium? 

We have to stress that if you are doing this or are planning to do this, please don’t. A bowl or a vase is a very unnatural environment for a Betta that will cause them to develop stress-related diseases. You will end up with a lethargic, dull-colored Betta that will most probably not live a very long life. 

Bettas require ample swimming space with aquarium plants and ornaments to play with and hide in to live a healthy and happy life. These activities stimulate their growth and breeding habits. Having them in a cramped bowl or vase will cause them to become lazy and bloated. Please don’t subject your Bettas to this kind of torture. Invest in a proper home for them.

Do Betta Fish need any Special equipment in their Fish Tank? 

Bettas don’t need any special equipment per se but they do require all the equipment that most commonly-found aquarium fish require: a filter, a heater and an air pump. 

Bettas are living creatures and obviously, they will produce waste that is released into the tank water. Thus, this tank water needs to be cleaned by passing it through a filter that removes the harmful chemicals from the water and keeps it clean and crystal clear. 

Secondly, a heater is needed because Bettas are tropical fish that require a water temperature of between 23 and 28 degrees Celsius. You may not necessarily need a heater if you’re living in a tropical region where it doesn’t get too cold. However, in most places you will need to invest in a heater for your Bettas in order to keep the water temperature warm in colder seasons.

Thirdly, an air pump is needed in order to keep the water moving inside the aquarium. This encourages the growth of beneficial bacteria inside the fish tank that helps remove dangerous toxins within the tank water.

How many Betta Fish should I keep in one Tank?

It is ideal that you keep only one Betta fish in one tank. They are called Siamese Fighting Fish for a reason. Male Bettas should never be kept in the same tank as they get agitated and fight with each other and ultimately kill each other. 

Final Verdict

With so many different options available in the market, it’s easy to see why so many beginner fish-keepers end up making the wrong choice when it comes to a good home for their Bettas. 

In the end, we have to give the crown to the Hagen HG Fluval Flex Aquarium. Its unique, sleek design makes it optimal to observe your Bettas in their environment and coupled with its bright LED lighting system, it is the ultimate package for viewing your Bettas in all their glory.
