How to make a Betta fish tank divider using pvc or acrylic
The method I prefer is to introduced the male betta fish into the breeding tank first. Next I use a separator or plastic holding container to house the female betta.
If you plan to keep two male betta fish in the same tank, you better have a divider to separate the two; otherwise, fins will be torn to shreds.
Betta fish are called the Siamese Fighting Fish because of its behavior towards other males of the same species. You cannot keep two or more males in the same tank. If more than one male fish are placed in the same tank, they will fight until only one of them remains. They will flare out their gill covers and erect their fins showing the other fish their fighting posture. This behavior is also why they are kept separated in small containers at the store.
We used a 10 gallon tank for this project
DIY Tank Divider for your Bettas and/or fishtank - YouTube
Male betta fish cannot live with other male betta fish. You CAN keep two male bettas together in one tank as long as they are separated by a divider. You can get a clear acrylic divider on ebay if you don't like the Canvas Mesh. They also come in a black color that is not see through. I also recomend using live plants so that it can be a more natural betta fish tank.Well, last night I got the one goldfish in betta's 6gl tank, granted he's inside his container all perforated (coudn't find separators for bowerd front tanks).Can I just put a separator in my 6-gl tank and have 1 betta on one side and 3 goldfish on the other side?! Oh, I also have a couple shrimps and was just about to get a pleco - I am starting to see algae puffs on the glass. I am changing 1/2 water once a week, I thought that should be enough. I cannot add any chemicals that would hurt my 2 plants either...Now, you could keep multiple males in one tank if you use a tank divider, but never in the same tank. Tank dividers allow for you to use one aquarium and divide it up into sections. This allows for you to keep multiple fish in one tank separated so they can not harm one another. You can use one heater and filter and essentially have multiple “tank areas” for your bettas.
If you decide to divide a tank, it must provide the proper ecosystem for each betta fish. What does that mean? A ten gallon tank should be divided into two separate five gallon sections, a twenty gallon should be divided into four ecosystems, and so on. The photo above is a great example of a divided ten gallon tank . While this method allows for housing many betta fish with less footprint, we do not support any tanks or sections that restrict the recommended size for a healthy betta fish.There are numerous ways to make divided tanks for betta fish, and if you want to keep more than one betta in the same tank, then a tan divider isn't just a nice idea, it is a necessity.
Most glaziers will cut glass to size for you. You can then silicone the glass inside your tank. This is a good, permanent solution. If you aren't going to filter each part of the tank separately, make sure that you leave a small gap at the bottom of the glass. It should be a large enough gap that your fish cannot swim under it, but enough to allow the water to flow through it. If you are planning to put substrate like gravel or sand in the bottom of the tank, then you will have to either filter each part separately, or come up with another filtration method that works. Cutting up an undergravel filter and fitting it to each part with separate uptakes may work, or using several small sponge filters attached to an air pump with multiple outlets may also work.
Perspex is much the same as glass, but it can also be drilled. (I would recommend that you get an expert to do this as it cracks quite easily.) You can then silicone it in the tank for a nice, permanent solution with good water flow.
