There are about 28,000 different species of fish known to us. And among these species of fish, Tetra fish are quite popular among beginner aquarists. There are about 700 extant species of tetra fish, and one of them is Serpae Tetra (Hyphessobrycon eques).
The common names of Serpae Tetra (Scientific Name: Hyphessobrycon eques) are blood characin, Callistus, Callistus Tetra, Jewel Tetra, Red Minor Tetra, and Red Serpae. The Serpae Tetra belongs to the fish family Characidae.
One of the main reasons that the fish is so popular is because of their deep red color. It makes the aquarium brighter and more attractive.

I will try my best to give in all the knowledge that I pursued keeping this fish as my pet buddy, and from my research as well. Keep reading to know more.
Origin, Habitat, and Distribution in the wild
The Serpae Tetras are one of the most colorful tetras that are widely available in various regions. It was 1882 when Steindachner described Serpae Tetra for the first time. Back in the days, Serpae Tetras was classified as Hyphessobrycon Callistus and then later changed to Hyphessobrycon eques.
Serpae Tetras are the native habitats of areas around Amazon basins, Guapore and Paraguay River basins in Argentina, Brazil, and upper Paraguay. In the wild, you can find Serpae Tetras commonly in slow-moving streams.
Most of these that you see in the market are captive bred. Meaning they are breaded in breeding facilities around the world. And only some of them are wild-caught. As we can easily find these tetras in the wild, they aren’t listed in the IUCN Red List.
The Serpae Tetras admires densely vegetated and stagnant waters of tributaries, ponds, and small lakes. They mostly swim close to the surface.
About Serpae Tetra
Serpae Tetra has growing popularity as one of the most beautiful aquarium fish. One of the alluring factors that these tetras have is their bright red color. This is the color that grabs your attention when you look at the tank with these tetras. These fish are a great addition to a beginner’s aquarium as they are a hardy fish; they can withstand harsh water parameters too. These tetras are inexpensive, too, so anyone can afford the fish.
Unlike most of the tetras, the Serpae Tetra have a twitchy spastic style of swimming. The Serpae Tetra tend to move in short bursts rather than swimming smoothly. As they are schooling fish looking at the pack moving together will relax your body and mind.
In this article, you can know about all Serpae Tetras behaviors, diet, tank mates, and the difficulty in taking care of them.
The Serpae Tetras are one of the most beautiful aquarium fish to keep. The color of these tetras is deep red on the sides. These fish have olive-brown color on their side profiles. Some of the serpae tetras have an outstanding black dot visible on the gills.
The tetra’s dorsal fin is black and has white rims. The anal fin is black in color as well, and the tips are white. The remaining fins are entirely red.
The fully-grown Serpae Tetras is about 1 to 1.5 inches long. When viewed from the side, the body is an elongated oval, laterally compressed.
The Serpae Tetras are very popular and widely available in different regions of South America, Argentina, Brazil, and Paraguay. These fish do not fall on the red list; thus, they are available in the wild as well.
Mostly the sellers breed these tetras in the community tank. Hence, they are available in pet stores and online stores that exports Serpae Tetras to other countries as well.
Life Span of Serpae Tetra
Like most tetras, the Serpae Tetra also has a life span of 3 to 7 years. If you can take care of them carefully, the fish can even live for more than seven years. There are reports of these tetras living for more than ten years in a very well maintained aquarium.
Serpae Tetra Price
The Serpae Tetra is mostly bred in captivity and is available in most regions like South America, Argentina, Brazil, and upper Paraguay. The cost of these tetras can range from $1.99 to $2.49 per fish according to the place you live in.
Fish Keeping Difficulty
Usually, Serpae Tetras are very easy to care for. As they are schooling fish, you need to keep them in a group of at least 6. However, they do not get along with most of the other fish, especially smaller ones. This tetra can have a habit of fin nipping and the target of relentless harassment to the smaller fish.
The Serpae Tetras mostly get along with their own kind or of their own size. Once they are comfortable in their environment, they are very easy to care for and breed too.
Serpae Tetras are very hardy fish; they can adapt to a wide range of water parameters. This makes this fish one of the best fish for a beginner aquarist.
It’s a bit difficult for a beginner to differentiate the male and female serpae tetra fish. However, some traits might help you differentiate the sex of serpae tetra. The best time you can separate this fish is during their spawning period.
Male Serpae Tetras colors are lighter, and their body is slimmer; their dorsal fins are entirely black. Whereas during the spawning period, the female tetra’s dorsal colors are red, and their body is oval as compared to male tetra. The male Serpae Tetras can get aggressive during breeding and can scare off other males.
The female Serpae Tetras, even when they are not the spawning season, have a more rounded body. In tetra fish, the females are mostly pale than the males. It is a similar case for the Serpae Tetra as the males look brighter and more colorful than females.
Serpae Tetra Fish Care
Since fish keeping is not the same as fostering other animals like cats and dogs, it can become a bit difficult in the beginning. However, once you understand the nature of the fish, you can take care of them better.
A proper diet and clean environment play a vital role in upbringing the health of human beings. Fish are not so much different from us. They need the right environment, clean water, and a healthy diet to be able to live up to their full potential. If you are not able to manage their needs, they cannot be healthy. So in order to take care of them, you must put a little bit of effort as they are living beings as well and deserve better living conditions.
In order to bring out Serpae Tetras activeness and brightness, you have to take care of their home. Read the following factors that you need to consider in caring for these tetras.
When you want to pet a fish, you must know the different criteria that you should consider before. One of the requirements is the tank size. The Serpae Tetras prefers tank size of at least 20 gallons, bigger aquarium the better as they will have much more space to play. As these tetras are schooling fish, you will need to keep them in a group, and considering the group size and other fish in the tank, you might need to upgrade your tank to higher volume. As for simple math, one inch of fish requires one gallon of tank. So in the case of serpae tetra, you will need at least a 20-gallon tank for at most six tetra fish.
When choosing the tank for these tetras, you must make sure that fish get enough space to swim freely.
There are different lighting choices for different kinds of fish. Most of the tetra fish choose to thrive in low lighting. Like most of the tetras, for serpae tetra, to resemble natural habitat, use low and subdued lighting. The dark tank environment can bring out the best coloration in these fish.
When you are lighting the aquarium tank for Jewel Tetras, you must also consider that the lights you are using do not heat up the temperature of the water. You must always remember to switch the lights on and off every day at the same time as per the requirements of the tank environment.
Decorations and Substrate
Serpae Tetras need lots of hiding places as they get easily scared, and it is their way to keep themselves from harm’s way. Hence, in order for the tetras to feel secure, they need to live plants and vegetation inside the aquarium along with the dark substrate.
The plantation must be in around the corners as the serpae prefers to swim in the middle areas of the tank. Some of the decorations for the fish can be driftwood, fern plants like Anubias and Java.
The driftwood provides a natural look and feels in the tank environment. As well as the different plantations can cause a difference in the shade of water, reflecting their natural habitat.
The Serpae Tetras are one of the easiest fish to handle. The fish is very less demanding and can eat almost anything with their omnivorous diet.
In the wild, Serpae Tetras can eat small live food such as insects, invertebrates, and worms. Whereas, in the aquarium, aquarists have to keep in mind about the fish’s little mouth. Hence, you mustn’t feed huge chunks of food. These tetras diet mostly contain small live or frozen insects, worms, flakes, pellets, ground grains, vegetables like lettuce, dried Brine Shrimp, and bloodworms.
Serpae Tetras can consume a very small amount of food at a time. Therefore, you must always keep in mind that you do not overfeed them. You also need to remove any uneaten food within five minutes.
Maintain Water Quality
An important factor in taking care of the Serpae Tetra or any other species of fish is to uphold the quality of water. Water gives the fish life, and keepers should be able to provide them with a balanced environment.
The artificial habitat can be very difficult to keep up with for different fish. Luckily, Serpae Tetra can handle and adapt to the environment you have set up very quickly. The water parameters should not change drastically. There must be regularity in changing to clean water bi-weekly.
You may be able to maintain the water quality by maintaining temperature, ph level, hardness, and the filtration system of the aquarium. They are described in detail further.
All the qualities inside the aquarium tank should be replicating fish’s natural habitat. This means that since the Serpae Tetras are tropical fish, the water temperature inside the tank should mimic the warm water of the tropical rivers.
The temperature in the aquarium may have an impact on the health of these fish if it is not steady or drops below the ideal temperature. The temperature of the tank should be between 72 – 82°F (22-27°C).
pH and hardness
The Serpae Tetras prefer lower ph range in their tank. As mentioned earlier, you must decorate their tank with driftwood. This driftwood can release tannins, which helps to maintain the lower pH level inside the tank.
The pH range for Serpae Tetras is from 5 to 7. They should not fluctuate drastically if you want the fish to thrive in the environment you have built. These tetras favor soft water, i.e., less than 60 ppm.
Sometimes, the water inside the tank can change drastically due to the presence of various toxins and fish excreting. Thus, we need to filter out the possible toxins from the tank. Having a filter can help you to keep the tank clean.
In the case of Serpae Tetras, the filters are necessary to keep the tank oxygenated. This will help during the breeding of these fish as well. The filter installation helps to decompose nitrates, phosphates, and organic matters.
The aquarium tank is an artificial environment for Serpae Tetras. The artificial environment can have various fluctuations, and hence, installing filters can help you cope up with these factors.
Aquarium Water Maintenance
As water is the source of life for Serpae Tetra and other fish, keepers should not compromise or contaminate them. The factors such as temperature, pH level, hardness, and filtration of toxins should be regular.
When you do not take care of the Serpae Tetras environment and water, it can have an adverse effect on their health. The owner should understand the nature of the fish and maintain their environment.
Therefore, any fish keepers need to replicate the fish’s natural habitat as closely as possible.
Serpae Tetra Tank Mates
For most initial fish keepers, understanding the compatibility of different fish within a tank is a problem. They are not sure whether they can keep Serpae Tetras with other kinds of fish or keep them isolated. For this, you should first know the nature of this fish.
Like most tetras, Serpae Tetras are also very friendly fish. They do not do well in isolation and must always be in groups of 5 to 6. The most frequently asked question about these tetras is, do they get along with other species? The answer, yes. The tank mates ideal to these tetra fish are active long fin tetras, like Barbs, Danios, and other larger tetras like rummy nose tetra. The fish also get along with bottom-dwelling fish.
However, you must know that Serpae Tetras do not get along with smaller species. These fish often harass and fight with the smaller once. Other species that they do not tolerate are the slow-moving fish. These fish tend to nip the fins of less active and slow-moving fish, and hence, you should not keep them together in a tank. Likewise, don’t keep the serpae tetra with aggressive and big fish, or else serpae tetra would be nothing but a dinner for these fish.
Additionally, you can also see Serpae Tetras fighting with other males within their own school. If this happens, you must not worry, as this is just the way of their playfulness. They do not severely harm each other.
