Neon Tetra Disease
The Neon Tetra Disease is the most common health issue you’ll most likely encounter as a Tetra fish owner. The disease is caused by a parasite called Pleistophora hyphessobryconis. The parasite lives in other hosts such as various live foods fed to fish.
Other fish could catch the disease if they eat a sick fish that dies from the same illness. The Neon Tetra Disease not only affects the Neon fish but also other fish species. It’s highly recommended to take immediate action or you could lose all the fish in the tank.
When a pet has Neon Tetra Disease, you’ll notice the following signs:
- Restlessness especially at night
- Fish not swimming with other tank mates
- Faded colors especially the red and blue stripes
- Lumpy body due to cysts
- Curved spine
- Fin rot
The disease has no cure and experts recommend that sick fish get euthanized. Once you notice a sickly fish, you should take it out of the tank so that it doesn’t get eaten by the rest, eventually infecting them.
You can control the disease by making sure the fish tank remains clean and the water conditions exactly match your fish’s needs.
White Spot Disease
With white spot disease, your fish will have white spots on their body. Ich is highly contagious and can quickly spread to other fish in your tank. If your Tetra is infected with Ich, make sure you quarantine them immediately. The disease can be cured by raising the temperature of the tank. There are also commercial Ich solutions available that can help to cure your fish. Consult a vet if the problem persists.

To prevent fin rot, it’s important to keep the tank clean and maintain good water quality. It’s also important to avoid overcrowding and ensure that any aggressive fish are kept separate from your Tetras. If fin rot does occur, it can be treated with antibiotics or other medications.

Black Spot Disease
Black spot disease, also known as black spot syndrome, is a common health issue among Tetras. It is caused by a parasite called Ichthyophthirius multifiliis, which attaches itself to the fish’s skin and gills. Symptoms of black spot disease include white spots on the body and fins of the fish, along with dark patches or spots that can appear on their head, body, and fins.
Your fish may also show signs of distress such as scratching against objects in the tank, loss of appetite, and lethargy. Treatment for black spot disease isn’t hard. The easiest way is to increase the water temperature to 80.5°F and add aquarium salt to the tank at a rate of 1 tablespoon per 5 gallons of water. It’s also important to remove any carbon from your filters and to perform regular water changes. Carbon in the filters can make the medication worthless. In severe cases, a medication such as copper sulfate may be necessary to eradicate the parasite.
Velvet disease, also known as gold dust disease, is a common ailment among Tetras. It is caused by the single-celled parasite Oodinium ocellatum, which attaches itself to the fish’s skin and gills. The parasite causes the fish to develop a golden-brown or yellowish coating on their body, giving it a velvety appearance. This disease can be fatal if left untreated. It’s important to recognize the symptoms and take action quickly.
Symptoms include lethargy, loss of appetite, clamped fins, and rapid breathing. If you suspect your Tetra has velvet disease, it’s important to quarantine them from other fish and treat the tank with a medication specifically designed for this type of parasite.
Dropsy is a condition that affects Tetras, as well as other fish species. It’s caused by a bacterial infection and is known for swelling of a fish’s abdomen. Other symptoms can be bloating, lethargy, loss of appetite, and difficulty swimming. The disease is often fatal if left untreated.
Treatment for dropsy includes antibiotics to fight the infection and water changes to reduce stress on the fish. It’s important to quarantine any affected fish and treat them as soon as possible to prevent the spread of the disease.
The Attention Needs of Tetra Fish
Tetra fish are active, social fish that enjoy being in a group. They should be kept in an aquarium with at least six of their own species, as this will help reduce stress and aggression. Tetras also enjoy having plenty of hiding places and plants to explore, so it is important to provide these in the tank.
Tetras are also curious fish that will often come up to the front of the tank to investigate their surroundings. They enjoy interacting with their owners and will often swim up to the glass when they see someone approaching.
Feeding Tetra Fish
Tetra fish are omnivores and should be fed a variety of foods. A good diet for tetras should include a mix of high-quality flake food, freeze-dried or frozen foods, and live or frozen brine shrimp. They enjoy commercial flakes, frozen foods, and some live foods. When buying commercial pellets or flakes for your fish, ensure that their food contains about 40 percent protein content.
Bloodworms, brine shrimp, and daphnia make the best frozen foods and these are available in most pet stores. Black worms and fruit flies make a good choice for live foods whenever you want to give your pet a treat.
When you feed your fish, only give them what they can eat within 20 – 30 seconds. It’s recommended that they be fed 2 to 3 times a day.

How Many Tetras Should be Kept Together?
When it comes to Tetras, how many should you keep together? The answer depends on the type of Tetra you have. Some species of Tetras prefer to be kept in small groups, while others do better when they are kept in larger schools.
For the most part, it’s recommended that you keep at least six Tetras together in one aquarium. Keeping at least six will allow them to form a school and interact with each other. Keeping fewer than six Tetras can result in stress and aggression between them.
