Betta fish is generally kept alone in a single tank as they are highly aggressive, territorial, and prefer to be alone. Owing to its temperament, two betta fishes cannot be kept in a single tank. But there is a solution. A divided betta tank is what you need if you want two or more betta fish.
A divided tank is not less than a community tank for your betta fish. The only difference between the two is that a divided tank has a divider in the middle, and only one part of the tank is dedicated to a fish. A divided betta tank is fairly easy to set up, and maintaining it is no different than a regular betta tank.
How To Set Up A Divided Betta Tank
Setting up a divided tank for your betta fish can be done in two ways. You can make the divider yourself using a plastic canvas mesh, or you can purchase a tank that already has an aquarium dividing system. Some people prefer making the divider themselves.
Making a tank divider is not that hard a job, and many people do it. Setting up your own divider in a tank allows you to keep multiple fishes in your tank and is a more economical and cheaper option. You can make a fine divider using a plastic mesh easily available in your nearest craft store.
Aside from purchasing the plastic canvas, it would help to buy binder splines to seal the divider to your tank. These splines are also pretty cheap and are easily available. Just make sure that you take your time and follow the instructions correctly.
Besides making a divider of your own, you can also purchase an aquarium that already comes with a divider. This kind of tank setup is readily available in any aquatic pet store and is quite reasonable. Although, purchasing such a ready-made product might cost you more than the previous method.
Also, make sure that if you are making the tank divider on your own, then try looking for plastic mesh that is a little darker in color. This makes sure that the visibility between the two fish is at its minimum thereby reducing the stress level in both the betta fish.
Conditions For A Divided Betta Tank
Once you have prepared a divider for your betta tank, you can bind it to your tank. This divides your aquarium into two parts for your two betta fishes. After having done this, it is time to figure out how to manage this new tank setup.
Managing water filtration and heating may be a little tricky in a divided betta tank, but it is not impossible. The water filtration system should be efficient in its working and set up so that both the parts of the water are equally filtered and cleaned.
The same goes for the water heater. As we all know, betta fish thrive in water temperatures ranging between 76 and 82 degrees F. Thus, a heater becomes necessary to keep the water warm and habitable for your betta fish. You need to add the heater in such a way as to heat both parts of the tank equally.
Here are some things to look into after setting up a divided betta tank for your betta fish.
Filtration And Heating System
As mentioned earlier, water filtration and heating system need to be added in such a way so that their effects are equalized between the two sections of the tank water. You can add one or two such systems to assure proper water quality and current in both parts of your tank.
The number of filters and heaters to add in a divided betta tank depends on the tank size. For instance, if your tank is about 10 gallons, then one heater should suffice. But in case the tank is of 15 or 20 gallons then two heaters are necessary for each part of the tank.
In water filtration, two small-sized filtration systems are recommended for each section of the tank. Sponge filters will be the best fit for your divided betta tank as it keeps the water current low and is also effective.
You need to understand that when we talk about tank size in the case of a divided betta tank, we talk about the length and not the height of the tank. If you plan to set up a divided tank for your betta fish, then it is advisable to get a lengthy and shallow tank.
A high tank can cause betta fish to jump from one side of the tank to the other, and this is the last thing you would want in a divided tank. Thus, make sure that the divider continues about two inches above the water surface to avoid jumping of betta.
In case one of your betta fish is sick, the water may be contaminated. Do not make the mistake of assuming that the other fish would be just fine. If one fish is sick, likely, the other is also sick if water condition is the real cause.
Thus, if you see any sign of contamination in the tank water, immediately prepare a quarantine tank for both your betta fishes. Do a thorough cleaning and filtering of water in the betta tank. Only after completing the water cycle, add both the fishes back to the divided betta tank.
After completing the tank setup for your betta fish, examine the behavior and activities of both your betta fishes. You may notice some agitation during the first few days but do not worry. Once they get used to the conditions, the betta fish will behave normally.
If you see any sign of over-aggression and stress in either fish, immediately transfer it to a backup tank. If stress levels are too high in your betta fish, it may ultimately lead to the death of your fish.
