While some aquarists keep these fish in tanks as small as 10 gallons, we think that’s insufficient. The recommended tank size for Green Neon Tetras is around 15 to 20 gallons (we prefer 20). An unmotivated or neglectful aquarist who knows everything about a fish is always worse than a diligent owner with average knowledge! Tank Size There are some important principles you need to follow if you want them to thrive, but this species won’t throw any curveballs at you.Īll you need to do is stick to the guidelines we list below and be consistent. Green Neon Tetra care is not very challenging. While it can be hard for us to notice a difference in something so small, it’s something to pay attention to when assessing the health of a fish you might want to buy. Size is something that can be influenced by genetics or quality of care (especially during developmental years). This makes them a bit smaller than their close relatives. The average Green Neon Tetra size is around one inch in length when fully grown. There’s something about having a bunch of them together that really makes the green stand out! Size We find that it’s usually easiest to identify Green Neon Tetras when they’re in a shoal (which they prefer to be).

Some of these fish can have more of a red patch than others, making them even harder to distinguish in a direct comparison. This combination makes the green coloration the most dominant and gives them their name. To go along with it, the blueish-green area on their bodies is much more vibrant and generally brighter. While it is present, it’s a lot less visible (sometimes barely noticeable at all). The difference when it comes to color is when you begin to look at the red. Their body shape and primary blueish-green coloring are almost exactly the same!Īt first glance it can be hard to tell the difference between these fish and their more popular relatives This is the reason why these fish are misidentified so regularly.įrom a distance or at first glance, they look a lot like the Cardinal Tetra or basic Neon Tetra. The appearance of the Green Neon Tetra is something that throws many people off. If you neglect them, the opposite is true. A good diet, suitable tank setup, and well-maintained water will all help them live longer. Like any fish, the lifespan of a Green Neon Tetra can be easily swayed by its quality of life.

This is shorter than their more popular counterparts. The lifespan of Green Neon Tetras is around 2 to 3 years.

Tributaries with a sandy substrate are a common hotspot for the Green Neon Tetra. This means the water they’re used to is fairly acidic and doesn’t get a ton of light (more on this later). They tend to prefer mellow blackwater areas that have large trees, vegetation, or debris nearby. The Negro and Orinoco Rivers are the most popular bodies of water where you’ll find them, but they have been known to journey out a bit from time to time. In the wild, you can find these fish primarily in the Amazon river basin in South America. It’s also why we’re hesitant to say that there’s one clear “winner” when it comes to the popular tetra species. This becomes clear when comparing diets or general temperament. While there are some physical differences we’ll dig into a bit further down, there are also a lot of similarities. Another common name for them is the False Neon Tetra because of this common misidentification. The Green Neon Tetra ( Paracheirodon simulans) is a fish that often gets confused with its more popular relatives.
