Tetras are peaceful, non-fussy fish that do not need too much care. These tiny colorful fish thrive when their living conditions resemble their natural habitat. So, you can keep your tetras happy by recreating a similar environment as they enjoy in the wild. While paying attention to the ideal water parameters and temperature for the fish, you should also analyze the water current that they prefer. So, do tetras like current?

Whether tetras like current or not depends on the tetra species. Most tetras prefer current because they come from rivers and streams with moving water. However, they like mild and steady water current. If the current is too strong, tetras will struggle to swim in the water and become stressed.

To understand the current requirements of tetras, we should take a closer look at their natural habitats. So, let us explore the origins of these aquarium fish.

Tetras In The Wild

We can trace the origin of tetras to America and Africa. Most varieties of tetras belong to the Amazon and other river basins of South America.

Tetras are schooling fish that live together in groups of twenty or more. They are generally peaceful fish that get along with their kind and other species. Due to their tiny sizes, they are easily intimidated by large fish.

Some tetras are aggressive. Such varieties are fin-nippers, and they bully others in their school as well as other fish.

In the wild, tetras prefer soft water with an acidic pH. They also like a water temperature of 75°F to 80°F.

Now, we already mentioned that the tetras live in streams and river basins. So, this fish prefers current. However, if you take a closer look, you will find that tetras typically live near the banks and in quiet creeks and basins. They are less likely to venture into areas with strong currents. Hence, we can conclude that although tetras like moving water, they are not comfortable in very fast-flowing water.

Ideal Water Current Settings For Tetras In Fish Tanks

In their natural habitat, tetras can easily swim out of areas with faster currents. They can swim around till they find areas with slow currents. However, they do not have this luxury in a closed space like a fish tank. Hence, it is important to maintain the right flow of water in an aquarium.

A proper water flow rate will keep your fish happy. If your tetras must constantly swim against the current, they will be under immense stress. However, if the water current is just right for their needs, they will frolic around and enjoy themselves. So, you should find that fine balance to ensure optimal living conditions for your fish.

In aquariums for tetras, the ideal current setting should be mild but steady. If you find your fish pressed against the walls of the tank, it indicates that the current is too strong. Hence, the fish are being pushed outwards towards the edges of the tank.

Tetras will also resign themselves to various hiding places in the tank if the current is too strong. They look for resting places in planted zones of the tank. However, it is not normal to find them hanging around the densely planted areas of the tank all the time. It could be because they are tired of the strong current.

Reduce the flow of water, and your tetras will be better off. Tetras will also appreciate the presence of dense plants. Not only does it replicate their natural habitat, but it also provides them plenty of places for relaxing.

Let us also look at the preferences of different varieties of tetras as they can vary from one species to another.

Ember tetras also like a lot of vegetation in their surroundings. Plants like Java moss and hornwort will help to produce the same effect as they enjoy in the wild.

Do Glofish Tetras Like Current?

Glofish tetras are an engineered type of fish with fluorescent coloring. Since they have the same physiology as other tetras, their habitat needs are similar.

Glofish tetras do not need fast-moving water. They will do well in slow water and thrive in water with moderate to low currents.

Make sure that their tank offers ample hiding places. It will allow the glofish tetra to rest if they are tired of swimming against the current.

Do Congo Tetras Like Current?

As the name suggests, the Congo tetras are from the Congo basin in Africa. They are commonly seen in the streams, ponds, marshes, and river basins of the area. Congo tetras have bright colors and a characteristic shimmer that makes them very attractive.

Congo tetras live in murky water in the wild. However, they need good filtration and water circulation in smaller tanks to stay healthy and happy.

Since they inhabit pools and water bodies with very slow-moving water, they will not appreciate strong water currents. Maintain a slow to moderate water flow, and your Congo tetras will enjoy their stay in a tank.

They will identify slow current areas and hang there if they are tired. However, if you find them going everywhere, you can conclude that they are comfortable, and the current is to their liking.

Since they like to swim, they prefer overhanging vegetation to dense plants in the substrate. A heavily planted tank will restrict their movement. They need plants only to hide and rest.

White skirt tetras have a pristine white color and translucent fins and tails. Their care is very similar to that of black skirt tetras.
