Origin and Distribution
Serpae Tetras are native to South America, specifically the Paraguay River basin. In the wild, you’d find them in slow-moving streams and flooded areas. They are known to be hardy fish that can tolerate a range of water conditions, which is one reason why they have become a popular choice among aquarium hobbyists.
In their natural habitat, Serpae Tetras tend to congregate in schools near the bottom of the water column. They are omnivores and will feed on a variety of foods, including insects, small crustaceans, and plant matter.
They were first introduced to the hobby in the 1930s, and since then, they have become a staple in the aquarium trade due to their striking appearance and active behavior.
Behavior and Temperament
Serpaes are generally peaceful but can be a bit nippy towards other fish, especially those with long, flowing fins. As such, it’s best to avoid keeping them with slow-moving or delicate fish, such as Betta fish.
One of the most interesting things about Serpae Tetras is their schooling behavior. In the wild, they swim together in large groups near the bottom of the water column. This behavior helps protect them from predators and also allows them to search for food more effectively.
In an aquarium, Serpae Tetras should be kept in groups of at least six to eight individuals to ensure they feel comfortable and can exhibit their natural behavior. When kept in smaller groups, they may become stressed and aggressive toward other fish in the tank, despite their tiny size.
In addition to their schooling behavior, Serpae Tetras are also known for being very active and playful fish. They are constantly on the move, darting around the tank and exploring their surroundings.
Serpae Tetra Tank Mates

When it comes to substrate, Serpae Tetras prefer a soft, sandy bottom. This can help prevent injuries to their delicate fins and make them feel more comfortable. Avoid using rough or sharp substrates that can cause harm to your fish.
Maintaining the right water conditions is crucial to the health and well-being of your Serpae Tetras. Here are some key water parameters to keep in mind when caring for your fish:
Serpae Tetras are tropical fish and require a water temperature between 72 and 80 degrees Fahrenheit. Keeping the water temperature within this range can help prevent stress and disease.
Serpae Tetras prefer a slightly acidic to neutral pH level between 6.0 and 7.0. Do check the pH level regularly to ensure it stays within the appropriate range.
Serpae Tetras prefer slightly soft to medium-hard water with a hardness level between 5 and 15 dGH. This can help prevent stress and keep your fish healthy.
Performing regular water changes is important for maintaining good water quality in your Serpae Tetra tank. Try to change 10 to 20 percent of the water in the tank every one to two weeks to keep the water clean and fresh. You might also want to try using a high-quality water conditioner when adding new water to the tank to remove harmful chlorine and chloramines. Avoid using untreated tap water, as this can contain toxins and chemicals that are harmful to your fish.
Diet and Feeding
What They Eat
Serpae Tetras are omnivores and will eat a variety of foods, including flakes, pellets, and live or frozen foods like brine shrimp and bloodworms. It’s important to provide a varied diet to ensure they receive all the necessary nutrients.
In addition to commercial fish food, you can supplement your Serpae Tetras’ diet with live or frozen foods like daphnia, mosquito larvae, and chopped earthworms. These foods are high in protein and can help keep your fish healthy and active.
When feeding your Serpae Tetras, it’s important to avoid overfeeding. Aim to feed them small amounts two to three times per day, rather than one large meal. This can help prevent digestive issues and keep the water in the tank clean.
Make sure to remove any uneaten food after a few minutes to prevent it from decomposing and causing water quality issues. Uneaten food can also contribute to poor water conditions and disease.
Adding supplements to your Serpae Tetras’ diet can help promote good health and vitality. Some supplements you may want to try include vitamin C, which can boost the immune system, and garlic, which can help keep parasites and other illnesses away.
Like any living creature, Serpae Tetras are susceptible to a variety of diseases and health issues. Here are some common diseases to look out for and how to prevent and treat them:
Ich, or white spot disease, is a common parasite that can affect Serpae Tetras. Symptoms include white spots on the fins and body, clamped fins, loss of appetite, and lethargy.
To prevent ich, make sure to maintain good water quality and avoid overcrowding in the tank. Treatment typically involves medication and raising the water temperature to 86 degrees Fahrenheit for a period of time.
Fin rot is a bacterial infection that can cause the fins to deteriorate and fray, and the culprits are usually poor water quality, injury, or stress. Symptoms include ragged fins, discoloration, and lethargy.
To prevent fin rot, make sure to maintain good water quality and avoid overcrowding in the tank. Treatment typically involves medication and improving water conditions.
Swim Bladder Disease
Swim bladder disease is a condition that affects the fish’s ability to control its buoyancy. It can be caused by overfeeding, constipation, or bacterial infection. Symptoms include swimming upside down or sideways, or difficulty swimming.
To prevent swim bladder disease, make sure to feed your fish a balanced diet and avoid overfeeding. Treatment typically involves adjusting the fish’s diet and adding medication to the water.
Dropsy is a bacterial infection that can cause the fish to become bloated and have raised scales. It can be caused by poor water quality, stress, or injury. Symptoms include swelling, lethargy, and loss of appetite.
To prevent dropsy, make sure to maintain good water quality and avoid overcrowding in the tank. Treatment typically involves medication and improving water conditions.
By monitoring your Serpae Tetras regularly and taking prompt action if you notice any signs of illness, you can help prevent and treat common diseases and ensure the long-term health of your fish.
