Tank Size

The minimum tank size for a Tanganyika killifish is 5 gallons. This fish is a small but hardy species that can do well in a wide range of water conditions.

While a 5 gallon tank is the minimum we recommend going with a 10 gallon tank if you can. The extra space will give your fish a little more room to swim and will also help to keep the water quality a little bit higher.

Water Parameters

The Tanganyika killifish is a delicate fish that requires very specific water parameters. These little guys are found in only one place in the world: Lake Tanganyika.

This lake is located in East Africa and is home to some of the most unique freshwater fish on the planet. The water is alkaline with a high mineral content.

It’s also home to some of the most venomous freshwater fish in the world. So, if you’re thinking about keeping Tanganyika killifish, be prepared for a challenge.

These fish are not for beginners. They’re very sensitive to changes in water parameters and even the slightest deviation can cause stress and disease.

If you’re up for the challenge, here are a few things you need to know about Tanganyika killifish care.

  • Water temperature: 75 to 82 degrees Fahrenheit
  • pH levels: 8.0 to 9.0
  • Water hardness: 10 to 20 dGH
  • Alkalinity Levels: 20 to 30 dKH

What To Put In Their Tank

These fish come from a variety of habitats, so there isn’t one “ideal” setup for them.

That being said, we recommend a setup that includes plenty of hiding places. Driftwood, rocks, and caves are all great options.

The substrate should be soft and sandy. Avoid anything too large or sharp since these fish like to dig around a bit.

Plants are a great addition to their tank, but make sure they’re tough enough to handle a little nibbling. Hornwort, Water Wisteria, and Java Moss are all good choices.

Common Diseases

Tanganyika killifish are a pretty hardy species, but that doesn’t mean they can’t get sick. In fact, there are a few diseases that these fish are particularly susceptible to.

The most common disease that these fish experience is ich. This is a parasitic infection that manifests itself as white spots on the body, fins, and gills of your fish.

If left untreated, ich can be lethal. However, it is fairly easy to treat if you catch it early.

The other disease that these fish are prone to is fungal infections. This is usually a result of poor water quality and can manifest itself as white patches on the skin or fins of your fish.

Fungal infections can be tricky to treat, so it’s always best to try and prevent them in the first place. The best way to do this is by maintaining clean and stable water conditions in your tank.

Behavior & Temperament

The Tanganyika killifish is a beautiful and unique fish that is native to the African Rift Lake of the same name. It is a peaceful and shy fish that prefers to stay hidden among the plants in its environment.

This fish is not aggressive and does not bother other fish in the tank. In fact, it is so shy that it may not even come out to eat unless it is the only fish in the tank. If there are other fish present, it may go hungry.

The Tanganyika killifish is a timid fish that is easily scared. It will often hide when someone comes near the tank or when there is a lot of activity going on around it. It is important to make sure that this fish has plenty of hiding places in its tank so that it feels safe.

This fish is not a good choice for a community tank because it is so shy and easily scared. It is best kept in a tank by itself or with other peaceful fish that will not bother it.

Tank Mates

The best tank mates for Tanganyika killifish are other peaceful fish that occupy different parts of the water column.

These fish are native to Africa and prefer to live in groups. As a result, they do best when they’re not the only fish in the tank.

Tanganyika killifish are also relatively small. This means that you need to be careful about the size of the fish you add to the tank.

You don’t want to add anything that could possibly see them as food.

With all of that in mind, here are some compatible Tanganyika killifish tank mates:


The Tanganyika killifish is a beautiful freshwater fish that is native to the Tanganyika region of Africa. These fish are not difficult to breed in captivity, but they do have some specific requirements.

The first thing you need to do is set up a breeding tank. It should be at least 20 gallons in size and filled with soft, acidic water. You can use a sponge filter to help keep the water clean.

Next, add some live plants and a few pieces of driftwood for decoration. Driftwood is especially important because it provides a place for the female to lay her eggs.

When everything is set up, add two or three males and one or two females to the tank. The males will be the smaller fish with the more colorful fins.

The female will lay her eggs on the driftwood. The male will then fertilize them. Once the eggs are fertilized, the female will eat them. This is normal behavior and you shouldn’t try to stop it.

The eggs will hatch in about two weeks. When they hatch, the fry will be very small and vulnerable. It’s important to keep the tank clean and to remove any uneaten food.

Feed the fry live foods such as baby brine shrimp or daphnia. You can also give them crushed-up flake food.

As they grow, you can slowly start to introduce them to larger foods.
