Betta Fish Tank Setup. How to do? All Answers here

When you first get a Betta Fish, setting up your tank is important.

The setup of your fish’s tank can impact how happy your fish is and how healthy they will be. Many steps are involved in this process, and the task can seem daunting.

However, if you follow this guide, you will come to the perfect Betta Fish Tank Setup in no time!

With proper tank preparation, your Betta is bound to live a long and healthy life.

Betta Fish Tank Setup: Getting Supplies

Before you do anything else, the first thing you should do is get the right supplies for your new pet. Here we will provide you with the proper materials needed to prepare your fish’s tank. We will also give you tips that are sure to improve your fish’s longevity.

Choosing the Right Tank

Your fish needs a new home. Picking out what kind of tank your fish will live in is the first step. Some people think that Bettas can live in any tank because of their small size.

The truth is that Bettas need room just like any other fish. A Five-gallon tank is a good place to start, but you can get an even bigger tank if you want. The more room your fish has to swim around in, the happier they will be in the long run. So keep this in mind when you make your decision.

Size is key, but the shape of your Bettas new home can be crucial as well. Since Betta’s natural environment is shallow, your fish might better enjoy a tank that is long horizontally. A short tank with a long length will allow your fish to swim with more ease and freedom. This will keep your fish content.

Get A Proper Filter

Filters are a must-have item for your Betta Fish Tank Setup. A glass bowl with some water won’t be enough to maintain the health of your fish. To keep your fish’s water clean and prevent disease purchase a filter with your tank. Some tanks may come with filters, many do not though.

When you are deciding on filters, don’t just settle on the first one you see. Bettas require a specific kind of filter. Since these fish are averse to strong water currents, you’ll need to get a gentle filter.

This kind of filter will keep the waters calm enough for you fish to swim in. A filter that allows you to adjust the flow can also serve this purpose. If you don’t have the right filter, and the waters are too rough, your fish can get stressed out.

Overall, you want your fish to be comfortable and have the best possible environment. By getting the right filter, you ensure that your Betta has that.

Heater Options

Bettas are tropical fish and, as a result, need warmer water to swim in. A heater is a great way to keep your fish’s water at a suitable temperature. Typically, Bettas like to be in water between seventy-seven to eighty degrees Fahrenheit.

A heater will keep the tank’s temperature at these ideal conditions. You will still want to watch the temperature though. Keep a thermometer in the tank so you can keep track of this. Sometimes your heater will have one included.

Still, it’s good to have your own thermometer so you can double-check the climate of the water.

If the water fluctuates between cold and warm climates too much your fish will be at risk. In short, the temperature of the water should be kept at a constant. Health complications can arise when the water is overly frigid or too heated. In cold water, you risk killing your fish. They might not eat and will swim less. In hot water your fish’s aging process will accelerate, resulting in premature death.

All heaters are not created equal. Some are more powerful and should only be put in tanks with a high volume of water. Get a heater appropriate for your tank size. In addition, if you have a tank that is under five gallon, don’t put a heater in. By putting a heater in smaller volume tanks you risk heating up the tank too much.

Adding Gravel to Your Tank

Gravel is another key ingredient to making your fish feel at home. Again you want to be discerning when choosing what to put in your tank. The type of gravel can really impact your fish’s environment. Small smooth rocks are the best option for your fish. By choosing these kinds of rocks, the tank will remain cleaner.

Big pieces of gravel create spaces between the pieces of rock. This will make it easy for food and other substances to get trapped. If you can’t reach this debris you can’t clean out the water properly. Size is important, but the color is up to your discretion.

Choose gravel in your favorite color to decorate the tank, or you could go with a multicolor approach. There are all kinds of great shades to fill your tank with!

Adding Plants to Your Tank

Plants are another great addition to your Betta fish tank setup. They will help your fish feel at home. Betta fish like hiding behind leaves, and using leaves for rest.

When you decide on plants, you can get real or fake vegetation to add to the water. There are pros and cons to both choices, but live plants have the most benefits.

They can help clean out your tank, and they are less likely to cause harm to your fish. If you add in real plants to your tank, look into getting substrate that will help your plants grow. Plants can make your tank a little harder to care for, but overall they are worth investing in.

If you want something more simple though, fake plants can work as well. Just make sure the plants are made of silk-based material. Also, you will want to check for any sharp edges or places where your fish could get caught.

The size of your tank will dictate how much you can add to your tank.

You have a lot of options when it comes to decorating, especially if you have a large tank. If you have a smaller tank though, you don’t want to fill it full of decorations. Otherwise, your fish won’t have any room to swim. On the flip side, if your tank is too sparse your fish won’t have a proper environment and might get bored.

Bettas like to hide in caves, so consider getting a rocky structure to put in your tank so they can nap or hide. Hollowed out logs also work for Bettas. Just make sure that anything you get isn’t too sharp. You don’t want your fish to hurt itself.

If you want something a little different, fish hammocks are another option you could try out. The hammocks are made out of are fake leaves. They use suction cups and let your fish sit near the top of the water.

This is the perfect resting place for your fish!

Moss and Mirrors

Mirrors could also keep your Betta occupied. Mirrors can make your fish think there is another fish in the tank. With this illusion set, your fish can flare his fins and get aggression out. You can purchase floating mirrors online and get your fish more active in the process.

Moss is another fun addition to the tank. A ball of moss can keep your fish interested and swimming. Free-floating moss balls are meant to help clean out the water but they can also be used as a toy.

Lastly, consider getting an LED light for your fish. While not strictly necessary, it can make your tank and fish look more eye-catching.

You can also help set up a sleep schedule for your fish. If your fish isn’t near a light source, use the artificial light to help the fish know when it is time to sleep and wake. Turn the lights on so he knows to wake up at a certain time. Then turn them off when it’s time to go to bed.
