The Ultimate Guide to Selecting The Best Plants For A Betta Fish Tank

Betta fish tanks can be used as simply as it is, or they can be elaborately decorated. An excellent place to start is by choosing plants that will look good with the décor of your tank while providing the fish inside with food and shelter.

In this article, we will tackle the needs of the betta fish and the best plants for a betta fish tank.

The Needs Of A Betta Fish

1. Temperature

Temperature is one of the most important factors when caring for a betta fish because Bettas thrive in warm water temperatures between 73 and 81 degrees Fahrenheit. 

Cold water bettas should be kept at 68 degrees or below, while high-temp bettas can handle temperatures up to 88 degrees.

One benefit of keeping your fish warm is that they will eat more. Bettas live on a diet composed mainly of small aquatic invertebrates, so raising their metabolism allows them to digest these nutrients better and get the protein they need.

Keeping your betta in an optimal temperature range also has other benefits. For example, if you have a high-temp betta, keeping your tank cool during the night can help them stay healthy and active during the day when you are sleeping.

2. Small Tanks

A small tank can be the perfect home for a betta fish since they can be very adaptable and playful, making them great candidates for smaller tanks. Some benefits of owning a betta in a small tank include the following:

  • The ability to keep your betta close by without having to worry about it getting lost in a large tank.
  • Less maintenance is required.
  • You can see your betta and monitor its health more quickly since there is less space to move around.

3. A Low Light Level

A low light level is a common need for betta fish. Bettas in low light levels are more active and spend less time hunting for food. This can lead to health problems with a high light level, such as stunted growth and decreased reproduction.  

Though not all bettas require low-light levels, those that do tend to be healthier and more active; there are many benefits to having a betta in a low-light level environment, including:

  • Healthier fish. Bettas in low light levels are more likely to stay healthy and live longer due to increased activity.
  • Increased reproduction. Bettas in low light levels are more likely to reproduce successfully because of their increased activity level.

4. Like To Lounge

Betta fish, like much other fish, enjoy a good nap. This is especially true for the betta fish, which have a trait called “lazybones.” Lazybones means the betta fish will take advantage of any opportunity to rest and lounge around. This includes lying on its back in the water or even on algae covered rock.

This relaxation mode has several benefits for the betta fish. For one, it helps to keep the fish healthy and happy by giving it plenty of time to relax and heal from injuries.

It also allows bettas to conserve energy since they don’t have to expend as much energy swimming or chasing food. Some people even believe that lounging makes a betta fish happy.

5. Prefer Low Flow

Betta fish, like other tropical fish, thrive in an aquarium with a low flow rate. A low flow rate means that the water is moving slowly and consistently through the tank.

This type of aquarium is also known as a “preferred low” aquarium. Bettas prefer steady, slow-moving water because it helps to keep their environment clean and healthy.

Bettas usually do well in tanks with a minimal flow rate of 1-2 drops per second (DPS). A tank with a higher flow rate can be too turbulent for them and can even cause them to stress out.

Additionally, low flowing water contains more oxygen which is beneficial to Bettas. Too high a flow rate can remove oxygen from the water, proving deadly to bettas if not corrected quickly.

Are plastic plants OK for betta fish?

The short answer is yes. Plastic plants are OK for betta fish. However, there are some things to keep in mind when adding them to your tank.

Bettas need hiding places and surfaces to help them maintain their balance. Plastic plants are a great way of providing these features without worrying about the upkeep of live plants.

As long as they are not made from toxic materials, plastic plants will be safe for your betta fish and can provide them with all the necessary features they need in their tank.

Do Betta Fish Eat Plants?

Betta fish are one of the most famous aquarium fish. They originate from Thailand but have been bred in captivity for many years. They are often kept in a small bowl, vase or jar with a few inches of water and plants.

Betta fish usually have a long, flowing finnage which can be very beautiful to look at. However, they do not eat plants, and they must be given regular feedings of pellets or flakes that are specifically designed for these fish.

Are Bettas attracted to a live plant?

A novice aquarium keeper may find it more daunting to maintain a live plant than a fake one, but it isn’t that difficult. Many live pants on the market are low maintenance and sure to be a hit with your bettas.  

Is there anything that betta likes in their tank?

It’s perfect for your Betta to swim in a tank with caves where it can hide and plants that provide plenty of shady areas. Bettas sleep and hide under leaves and enjoy lounging on them. Just be careful with ornaments, as their delicate fins could easily be snagged or torn.
