Energetic, playful, and vibrant, cardinal tetras make wonderful additions to communal freshwater. Their peaceful nature means that they’ll get along with like-minded fish with zero issues, while their straightforward dietary needs make them easy to care for.
While these fish can be difficult to find in most local fish stores, many online fish stores sell these unique, elusive fish. If you’ve been thinking of adding cardinal tetras to your tank, read on!
Buying Cardinal Tetras Online: A Quick Overview
Cardinal Tetras are native to Brazil and Venezuela, and were first discovered in 1956 by Schultz. They look similar to the ever-popular neon tetras, but are slightly bigger with red stripes that span the entire length of their bodies, as opposed to neon tetras, whose strips end midway through.
The vast majority of cardinal tetras sold on the market are wild-caught and not farmed, because these fish are notoriously difficult to raise in captivity. This means that cardinal tetras are more resilient against illnesses because they are less likely to be interbred within the same genetic lines.
When buying cardinal tetras online, it is important to learn as much about the seller and their livestock as possible. This way, you’ll maximize your odds of purchasing healthy, good-quality fish!

Here are some other guidelines on how to purchase fish for your aquarium.
Which Is Better – Neon or Cardinal Tetra?
It can be easy to get Neon Tetras and Cardinal Tetras confused because they look similar, but there are actually several key differences between the two.
In general, neon tetras are seen as more beginner-friendly fish because they can tolerate a wider range of water conditions. This means that they are better able to adapt to the water fluctuations that are part and parcel of every learning curve for newbies to the hobby. To learn more about some common mistakes beginners make and how to avoid them, check out this article.
However, cardinal tetras tend to be larger and brighter, which can make them slightly more visually striking compared to neon tetras. Their red stripes extend throughout the length of their bodies, whereas the red stripes on neons stop midway through their abdomen.
Another factor to consider is the fact that neon tetras are typically cheaper and easier to find because they are easily bred in captivity. However, this means the quality of fish will vary dramatically depending on your source. Breeders who have subjected their neon tetras (And If you want to know the difference between a male and female Neon tetra, You can check it out here.) to multiple generations of selective breeding will produce fish that are more susceptible to illnesses. In contrast, cardinal tetras are usually wild-caught – which makes them more expensive, but also more hardy.
How Many Cardinal Tetras Should Be Kept Together?
Although cardinal tetras are larger than the closely related neon tetras, they remain rather tiny fish that can only grow up to two inches long. For this reason, cardinals should absolutely be kept in groups to make them feel at ease. We recommend a group size of at least 6 cardinal tetras, though 10 or more fish is ideal.
Buying cardinal tetras online can feel like a stressful experience, but there’s absolutely no reason why this should be the case.
Reputable sellers will do everything they can to put their customers at ease – whether it’s by providing top-notch customer service, or by guaranteeing live arrivals. When you buy from online fish stores that care about the customer experience, there’s no reason to feel stressed out by the uncertainty.
