Betta fish are one of the most popular fish to keep as pets — not only are they beautiful, but they’re pretty low maintenance. But there’s one famous rule when it comes to taking care of a betta fish, and that’s to not allow them to share a tank with other betta fish. Believe it or not, this rule isn’t totally true. Male bettas are notoriously territorial toward other male bettas, so they definitely can’t share a tank. But female betta fish aren’t the same, and they can comfortably live together. Male bettas can live with other fish, as long as the other fish are not aggressive.
You can get a simple tank for your betta, like a globe-shaped bowl with some pebbles on the bottom. The problem is that not only are these less interesting to look at for you, but they’re also less interesting for your fish. Betta fish can actually exhibit signs of anxiety and boredom, which is why getting a large enough tank with different features and places to hide will help keep your betta happy.
Once you have the tank and the fish, you have to then consider the most important aspect of all, the water itself. Everything from temperature to pH has a big impact on the well-being of your fish, and the same goes for betta. Tap water is actually well suited for betta because, unlike distilled water, the minerals have not been removed. The only thing you need to do to the tap water is condition it, which is the simple process of adding a conditioning fluid.
Another factor that makes betta easier to take care of is that they don’t need too big of a tank. But that doesn’t mean they should be kept in a tiny cup — while they can survive, they’ll be happier in tank that’s at least tthree gallons. These are some of the best betta fish tanks to buy online.
