Water Conditionsįinding the right water conditions and parameters is essential if you want your fish to thrive, no matter how hardy they might be. Neon Tetras are schooling fish, so you need to provide enough room for the whole crew! This will help them feel safe, stress-free, and not too cramped. While they’re definitely considered nano fish, the reason why this species won’t do well in a super tiny tank (think 5 gallons) is simple. However, we’re strong advocates for 20 gallon tanks being the better size to shoot for. You shouldn’t consider a minimum tank size of anything less than 10 gallons. The best way to keep your Neon Tetras happy and healthy is to provide them with a habitat that’s comfortable and fine-tuned to their needs. No matter how hardy a fish is, you should always aim to give them the perfect environment in which they can thrive. You can expect this range to drop if you neglect them for long periods of time. Once they’re set up in an established tank with the proper conditions, the average Neon Tetra lifespan is somewhere between 5 to 10 years. As long as you provide them with the basic care and water conditions they need, they should do just fine! The Average Neon Tetra Lifespan This is obviously a huge advantage (especially if you’ve had to care for high-maintenance fish in the past). They’re surprising hardy and don’t require a ton of attention like other fish. Keeping a Neon Tetra healthy is not very difficult. Most of their head is taken up by large beady eyes which sit almost perfectly level with their mouth. Their bodies are thin, narrow, and torpedo-shaped. However, bred fish usually don’t get much larger than one and a half inches. In the wild, they can reach about two and a half inches in length. When it comes to size, Neon Tetras are not very big at all. This allows them to blend into their natural habitat and hide from predatory fish.

Aside from those three colors, Neon Tetras have a translucent body. The belly of the fish is colored in a neutral white. For Cardinal Tetras, it runs through the entire length of the fish. For Neon Tetras, the stripe only crosses half of the body. While they do look similar, the biggest difference is the size of the red stripe. Because of this red streak, Neon Tetras are commonly mistaken for Cardinal Tetras. It’s believed that the stripe is used to improve visibility among different types of tetras.īelow the blue stripe, there’s a partial red stripe that starts at the middle of the fish’s body. This stripe has a somewhat iridescent quality and reflects light very well. Splashes of red, white, and blue cover their bodies.Ī shiny blue stripe extends from the tip of their heads to the adipose fine, which is a small rounded fin above the tail. As their name would suggest, these fish have a noticeably vibrant color pattern. The most distinct aspect of the Neon Tetra is its color. Their popularity continues even today due to their beauty and relatively easy care. Thanks to their stunning good looks, these fish quickly became a hot commodity among enthusiasts. Neon Tetras (also called paracheirodon innesi) were classified back in the 1930s when they were first brought to the United States from South America. They’re most prevalent in Peru, Colombia, Brazil, and sometimes Ecuador. While most of the fish sold are bred in captivity, you can find Neon Tetras swimming throughout the Amazon Basin. However, there’s more to this fish than meets the eye. These fish are one of the most popular species for aquarists around the world.
