You can find these beautiful fish in various colors, including silver, gold, and even neon green.

How to Care for Silvertip Tetra?

1. Tank Size

Silvertip tetras are small fish, so they don’t need a large tank.

A small group of them can do well in a standard 10-gallon tank, but for the best results, it’s better to start with a tank that is at least 20 gallons. This will give them enough room to swim and be active.

As a general rule of thumb, you should provide three gallons of tank space for each adult tetra.

2. Temperature

The Silvertip Tetra is a freshwater fish from South America. In their natural habitat, the water temperature can range from 68 to 82 degrees Fahrenheit.

From our experience, we found that the ideal water temperature for them with around 72 to 74 degrees.

3. PH Level

This fish can tolerate a wide range of pH levels, but it thrives best in neutral water. So, a pH level of 6.0 to 8.0 is ideal for them.

4. Lighting

When lighting your Silvertip Tetra aquarium, a dimmer is usually better. This will help bring out their natural gold and yellow colors, making them shine.

Plus, a darker substrate will make them stand out even more. So if you want your fish tank to look spectacular, consider going with a low-light setup. Your Silvertip Tetras will thank you!

5. Filters

One of the most important things to consider when setting up an aquarium is the type of filter you will need.

There are a variety of filters on the market, but not all of them are created equal.

When choosing a filter for your Silvertip Tetra, there are a few things you need to keep in mind.

The first thing to consider is the size of your aquarium.

The filter you choose should be able to accommodate the amount of water in your tank.

If you have a smaller aquarium, you may not need as powerful of a filter as someone with a larger tank.

The second thing to consider is the type of filtration you need.

There are two main types of filters: mechanical and biological.

Automatic filters remove physical debris from the water, while natural filters help to break down harmful chemicals.

If you have a Silvertip Tetra aquarium, you must choose a filter that can provide both mechanical and biological filtration.

The best way to do this is to select a filter that has a combination of both.

The third thing to consider is the maintenance required for your filter.

Some filters require more maintenance than others. If you do not want to spend a lot of time cleaning your filter, you may want to choose a less maintenance-intensive option.

6. Tank Decoration

One of the best things you can do to decorate a tank for Silvertip Tetras is to use rocks, driftwood, and caves.

This will help create a more naturalistic environment for the fish while also providing them with hiding places when the light is turned on.

Using sand as a substrate will also help to recreate their wild habitat.

Silvertip Tetra Diet

The silvertip tetra is an omnivore, meaning it will consume various things, including insects, plant matter, and anything else it can find in the wild.

In captivity, it’s essential to provide a high-quality diet with a lot of variety.

The silvertip tetra’s diet base should be premium flakes or dry granules.

Look for formulas that are nutritionally balanced or that are focused on enhancing color vibrancy.

In addition to the flakes, provide high-protein snacks such as bloodworms, Daphnia, brine shrimp, and other meat-based foods. You can also offer freeze-dried, frozen, or live foods.

By providing a diet rich in nutrients and variety, you will help your silver silvertipstay be healthy and thrive.

Silvertip Tetra Compatibility

Silvertip tetras are schooling fish, so they must stay in at least six or seven groups. If possible, it’s better to have a shoal of ten or more.

When kept alone or in small numbers, silvertip tetras tend to get very aggressive.

This is because they rely on the rest of the group to stay comfortable exploring the tank. Without that support system, they live in constant fear and usually don’t have a long lifespan.

Silvertip tetras are a little more aggressive than other tetra species as a whole.

Even in huge gatherings, they have a propensity of causing fish harm by nipping fins.

They will naturally target long-finned individuals, but they can also bite any fish unfortunate enough to get in the way. Fortunately, that problem is easy to avoid with a bit of forethought.

Silvertip Tetra can be kept with the following fish:

  • Black Skirt Tetra
  • Buenos Aires Tetra
  • Zebra Danios
  • Molly Fish
  • Most Types Of Rasboras
  • Blind Cave Tetra
  • Cory Catfish
  • Serpae Tetra
  • Peaceful Types Of Plecos
  • Platy Fish

Silvertip Tetra Breeding

Silvertip tetras are willing to breed in captivity, making them a good choice for beginner fish keepers who want to try their hand at breeding.

These fish are egg scatterers, meaning the female will deposit eggs all over the tank. Usually, they prefer to lay them among plants for security.

The adults don’t exhibit any parental instincts, so it’s essential to remove them from the tank after spawning has occurred.

This can be done using a breeding trap, a small cage that allows the fry to swim out but keeps the adults from getting back in.

To maximize survival rates, set up a separate breeding tank. The tank will serve as a place for spawning and a nursery tank.

The breeding tank should be well-planted and have a dark substrate, as this will help the fry feel more secure.

It’s also a good idea to add a piece of driftwood or a cave, as this will give the adults somewhere to hide.

The water parameters for the breeding tank should be as follows:

  • pH: 6.5-7.5
  • Temperature: 72-79 degrees Fahrenheit
  • Hardness: 5-20 dGH
  • Ammonia and nitrite levels should be zero, and nitrate levels should be less than 20 ppm.

After you set up your tank, the fish will spawn over the next few days, and the fry will be born in another 10-14 days.

Once the fry is born, you should feed them a diet of live foods such as baby brine shrimp or micro worms. You can also provide them with commercial fry foods.

It would help if you fed the fry several times a day, and water changes should be done regularly to keep the tank clean.

As the fry grows, they can be slowly introduced to flake food and frozen foods.

Once they reach about half an inch in size, you can move them to a community tank.

Possible Diseases and Prevention

While Silvertip tetras are hardy fish, still, like other fish, they are susceptible to illnesses.

Here are some common diseases that can affect these fish:


 Ich, or ichthyophthiriasis, is a highly contagious disease caused by the parasitic freshwater fish Ichthyophthirius multifiliis.

Infected fish develop white spots on their skin, fins, and gills and may die if left untreated.


1. Raise the tank temperature to 86°F (30°C) for 3-5 days.

2. Add 1 teaspoon of salt per gallon of tank water.

3. Treat with a commercial ich medication, following the directions on the package.

4. Do a 20-50% water change every other day.

5. Clean the tank and remove all decorations.

Fin Rot

Fin rot is a common disease that can affect many different types of fish.

It is caused by a bacteria called Pseudomonas aeruginosa, and it can cause the fins of fish to become frayed and disintegrate.

Fin rot can be fatal if it is not treated quickly, so it is essential to be aware of the signs and symptoms of this disease.


1. If you have more than one fish, it’s essential to isolate the sick ones. This will help prevent the disease from spreading and make it easier to treat.

2. Do a partial water change every week and vacuum the gravel to remove any waste.

3. Treat the water. Various products on the market can help treat fin rot. Be sure to follow the directions carefully and only use safe products for your fish.

4. Feed them high-quality food that is rich in vitamins and minerals.

5. If your fish are not responding to treatment, it’s best to take them to a vet who can prescribe medication.

With proper treatment, most fish will recover from fin rot. However, it’s essential to take steps to prevent the disease from occurring in the first place.

Be sure to clean your tank regularly and feed your fish a nutritious diet.

Taking these precautions can help keep your fish healthy and happy for years to come.

Velvet disease

Velvet disease is a devastating fish disease that affects freshwater and marine environments.

The disease is caused by a parasitic dinoflagellate (single-celled algae) called Piscinoodinium pillulare, which infects the skin and gills of fish.

Velvet disease is highly contagious and can spread quickly through an aquarium or fishpond.

Infected fish may show various symptoms, including loss of appetite, lethargy, and flashing (rubbing against objects in the tank).

In severe cases, the parasites can cause death within days.

Aquariums and fishponds should be regularly inspected for signs of the disease, and any fish showing symptoms should be immediately removed from the tank.


1. Quarantine infected fish in a separate tank.

2. Use antibiotics to treat a bacterial infection and copper sulfate to treat the parasitic infection.

3. Do a partial water change every week and vacuum the gravel to remove any waste.


Is Silvertip Tetra Aggressive?

No, silvertip tetras are peaceful schooling fish. They, however, tend to be somewhat more aggressive than smaller fish kinds.

They also nip on similar size fish species frequently.

Can We Keep Silver Tip Tetra with Betta Fish?

Yes, you can keep Silvertip Tetra fish with Peaceful Betta fish breeds.

Crescent Betta fish is considered one of the best tank mates for Silvertip as they are both peaceful and lively.

However, it’s important to note that not all Betta fish breeds are suitable for sharing a tank with Silvertip Tetra fish.

For example, the Plakat Betta is a particularly aggressive breed that should not be kept with Silver Tips.

How Many Silvertip Tetras Should Be Kept Together?

Maintaining a minimum of six Silvertip tetras in one tank is advised since they are schooling fish. They do well when kept in a group and require a lot of swimming.

Silver Tip Tetra becomes hostile if maintained alone, as previously said.

Are Silvertip Tetra Fin Nippers?

If you’re thinking about getting a Silvertip Tetra for your aquarium, you may be wondering if they are fin nippers.

The answer is yes, however, keeping them in a group usually won’t bother other fish’s fins.

So, if you’re looking for a peaceful community fish, Silvertip Tetras is a good option.

Just be sure to keep them in a group of at least 6-8 fish.
