I have always been a fan of the Betta fish. Each one has their own unique personality and they are very beautiful. A recent trend among fish owners is to keep them in a plant vase, usually under some kind of flower arrangement. While this looks very nice, I found out that it is not the best idea for the health of your fish. Unfortunately, I found out the hard way and had one of my Betta fish die after keeping him in a vase. Shortly after his passing I did some research and found out why you shouldn’t keep your fish in a vase and now I’m going to pass the information on to you.
Not enough oxygen
When using a vase to house your Betta fish, they won’t get enough oxygen to live a healthy life. They need to be able to reach the surface of the water to get air. The plant on the top of the vase will block them from doing that so they won’t be able to get any oxygen. Another problem that can arise is the toxins that will fill the water when the plant dies. They can be harmful to your fish so it’s best to avoid them altogether.
Not enough space
Another problem with the vase tanks is the lack of swimming room for the fish. Your Betta fish tank should be at least 5-6 inches long to give them plenty of room to swim around in. Too little of a swimming area can cause your fish to be stressed and become unhealthy.
Lack of nutrients
Bettas need to be fed daily to ensure they get all the nutrients they need. Some people think that the fish will survive by feeding on the roots of the plant that sit on the top of the vase. That is a wrong thing to believe! In the wild, these fish eat insects and their larvae so they need meat to survive. Most fish food you buy at the pet store for Betta fish is meat based. Assuming the fish will survive by eating the plant roots is definitely not a good idea.
Poor water conditions
The water in your fish tank needs to stay clean and fresh. You should change the water at least once per week to make sure harmful toxins don’t build up in the water that can harm the fish. If the plant in the vase dies, it can also release harmful chemicals into the water that are unhealthy for your fish.
Now that you know about the dangers of keeping a Betta fish in a vase, you should definitely think twice before you house yours in one. Your fish will have a healthier and happier life. If you absolutely must keep your fish in a vase, make sure it has surface are to get oxygen, food every day, weekly water changes, and if the plant dies or starts to die, remove it immediately to prevent harmful toxins from getting into the water.
