Flag Tetra Overview
The flag tetra’s scientific name is hyphessobricon heterorhabdus. This fish is so unique because its body pattern resembles the Brazilian flag. At a glance, when you are looking into their bodies, it really resembles the latter flag. It is also interesting to know that the species is actually a native of Northern East Brazil.
The fish can be found in the creeks, ponds, floodplains, as well as tributaries around the local area.
Flag Tetra Appearance
The Flag tetra is a peaceful species with a long, slender olive body that is sometimes silverish. There are stripes of red, black, and yellow across its body. The females tend to be bigger than the males.
This fish is categorized as a shoal fish. You can easily add this fish to the community tank. However, these buddies can survive longer with the other tankmates, who are also similar in size. To ensure that you can give them the best care as their pet owner, you will want to mimic the natural habitat to be as close as possible to its origin.

It has been a common favorite for many aquarists across the globe because of its easy care in captivity. The availability is also reliable. You can find the fish in any nearby pet store in your location.
The unique species is easy to care for, but it will provide certain challenges for the owners to breeding them. We will explain this point later in the breeding guidelines section.
Flag Tetra Tank Requirements & SetUp/Tank Guides
The tank requirements are not complex. Since your flag tetras are used to living in particular places, like creeks, floodplains, ponds, etc, it can be simple to replicate the condition.
First things first, you will want to tweak the environment to provide ample shade and mature vegetation. Clearwater is a must so that the fish can be healthy and active on a daily basis. The fish is a schooling creature. It takes effort to prepare your aquarium so that the fish can accept their new habitat.
Flag Tetra Tank size
As mentioned, these tetras are doing their activities in school. Keeping them in a group in your aquarium will be the top priority. You want to make sure that the tank measurements are adequate for them to live, including their tankmates. They need more space to swim and explore.
Thanks to the size of the fish, even 10 gallons of water is enough to cater to a small group of tetras. But if you plan to add more tankmates and beautify your aquascape, you will need to prepare a larger tank to start your rodeo. The tank size will also depend on the number of total specimens you want to add to your tank.
The fish tank size should be good enough to make your pets more comfortable conducting their routine activities and living with their tankmates.
Unfavorable aquarium conditions will come with inconveniences for your fish. It will also make it harder to care for them maximally. That is why you need to setup a fish tank that is able to support their lives.
When it comes to the filter system, you will need to install a filter that can provide a water flow level of at least four times the volume of the fish tank.
If you live in a four-season country, you will need to install a heater for the winter months. If not, your fish won’t survive the coldness of the season. Make sure to add the aquarium thermometer as well to track the temperature levels in your aquarium.
After installing the filter and heater, you need to pour in the tap water. As you probably know, the tap water itself is not ready to accommodate your pets. You will need to get the water ready first before proceeding. Switch on the filter and heater and let them cycle for a few days before adding your flag tetras and their tank mates. Some people use a 5-day cycle because it is a common rule to follow. But to be sure, you could extend the maturity cycle to 10 days. It is better to be ready than not.
The water conditions will be the key to your fish’s survivability and longevity. There are some water parameters that you will want to follow to make sure that they will be up and healthy on a daily basis. The ammonia and nitrite levels should be lower than zero. Keep in mind that this fish is docile. Even slight changes in nitrates can make them faint. The nitrates must be under 20ppm.
The temperature of the water should be around 20 to 25 degrees Celsius. The pH level should be around 5.5 to 7. Meanwhile, the water hardness can be light to moderate.
The gentle current is the ideal water condition for the fish. Make sure that your filter can provide a stable flow level to the tank community space. Since it is a tiny fish that you are about to care for, consider picking a filter that won’t suck your fish.
The decoration is also a crucial part of caring for the flag tetras at your home. It is a method you can use to mimic the real habitat of the fish so that they will feel at home when added to your community fish tank. You can choose these important objects when decorating the tank for your tetras:
- Dried leaves litter the litter
- River sand substrate
- Algae magnet
- Floating plants
- Dim lighting
To make them look vibrant in your aquarium, you could replicate the black water for the particular species of fish.
Maintaining the water
Maintaining the water quality will be one of the keys to caring for your tetra to the max. The water change should be at least 20%, which you can do every two weeks. But if you add more tankmates to your larger aquarium, you might need to do the water cleaning more frequently.
Clean the filter regularly. Remove dead plants if they are not wanted. Also, check on the overgrown plants as well.
Flag Tetra Tankmates
The flag tetras can live peacefully with the other tankmates in the aquarium. It is a school where they will do most of their activities in groups. They can survive much longer by shoaling as a group of a minimum of six individuals or more.
You will want to focus on the tankmates that are similar in size to them. The larger fishes are out of the option because they can eat your tetras.
Their compatible tankmates are
- Small gouramis
- Dwarf cichlids
Your little buddies won’t survive alone. They will have good moods and morals when doing everything together with their schoolmates.
Security for your fish is a top priority. That’s why you don’t want to add other fish that could threaten their lives.
But don’t add too many tankmates to your aquascape since this will distress them. You can also add invertebrates and snails to serve as natural cleaners of your community tank. Snails are also indifferent towards other fishes.
Flag Tetra Diets/Food/Feeding
It is an omnivorous fish so that you can literally give it anything. But their most favorite foods are small invertebrates, larvae, as well as blood worms.
You can also give them plant-based foods like pellets, flakes, etc., but they won’t get bored with the live foods. Frozen foods can also be a consideration if you don’t have a stock of live foods at home. Provide a good mix of diets so that they won’t get bored with your offers.
You should feed them once or twice a day. Overfeeding your fish will make them sick and obese.
Flag Tetra Breeding guidelines
The flag tetras care is easy. But breeding them in captivity is a hard thing to do.
You will need to set the correct environment in your tank in order to trigger the spawning. It is much better to prepare a dedicated tank for breeding. After spawning, you will want to take the males back to the main tank since they tend to eat their fry. You can move the kids back to the main tank when they reach a similar size to an adult. Consider getting help from your experts if you are not sure about the breeding process.
