Some fish can live in strong currents, while others thrive well in moderate currents. So while setting up a new guppy aquarium, you might wonder, do guppies like current?

No, guppies do not like a current. In the wild, guppies are usually found in ponds, lakes, and rivers with slow-moving waters that have a mild current. Excessive current can have several harmful effects on guppies, like low immunity, exhaustion, stress, illness, and lethargy, to name a few.

Now, let’s understand how a strong current can affect your guppies. But first, let’s see…

What Is The Natural Habitat Of Guppies?

Guppies are usually found in freshwater bodies.

However, they can even survive in brackish water.

You will often find guppies in lakes, rivers, ponds, streams, small pools of water, etc.

Guppies prefer slow-moving water in the wild.

They thrive in moderate water flow. Due to their small size, they avoid fast-moving water or areas that are excessively deep.

Let us now understand what causes current and if it is required in your aquarium?

What Causes Current And Why Current Is Beneficial In An Aquarium?

Current is mainly caused by electricity-driven filters, air pumps, and air stones. Guppies are messy fish.

That is why a filter is essential in a guppies aquarium.

Current helps in flushing away the waste materials from the aquarium water.

Also, current in moderation is essential in any aquarium.

Water temperature is maintained throughout the aquarium due to the flowing water.

Apart from that, the current causes surface agitation.

This results in an increase in the oxygen levels of the water. Oxygenated water keeps guppies healthy.

Furthermore, a biological filter that contains beneficial bacteria needs water flow to remain active.

It also assists in keeping the ammonia and nitrites level down.

Also, if you have any aquatic plants in your aquarium, water flow is required.

The flowing water helps to bring the carbon dioxide to the plant’s leaves.

Okay! Now you know some amount of current is essential in the aquarium.

Let’s now understand how much current is beneficial for guppies and the signs that determine if the current is high.

How Much Current Should Guppies Have? What Are The Signs Of Too Much Current?

Any fish, including guppies, love swimming. They love to swim all over the place and at their own pace.

Some fish, like hillstream loaches and tetras, like the current. While some other fish, like guppies, do not prefer current.

For your guppies, the lesser the current, the better it is for their health.

Guppies grow to their optimum health in moderate water flow.

You can determine if the current is high for your guppies by observing the following things:

  • You find your guppies struggling to swim freely. They get flipped over either horizontally or vertically due to the current.
  • You find a change in their swimming pattern. They will swim in one particular direction and not all over the aquarium.
  • You find your guppies sitting at the bottom of the tank. It is a clear indication that they are exhausted and need some rest.
  • You find your guppies have stopped swimming; they stay at a place without any movement.
  • You find that your guppies’ body movement has stopped as they are finding it difficult to swim. They are moving just due to the current.

Alright! You now know how to determine if the current is high for your guppies. But does it harm your guppies, and in what way?

What Happens To Guppies If The Current Is Strong?

If the water current is too high, your guppies will face the following problems:

  • Stress: Stress occurs when the environment is not conducive. Guppies thrive in freshwater bodies where there is limited current. If they suddenly get a lot of current in the home aquarium, it leads to stress as they are not used to it. Stress is not at all good for the well-being of your guppies.
  • Illness: Your guppies can get sick and suffer from diseases due to high current. If you have fancy guppies, excess flow can damage their long fins.
  • Lethargy: Your guppies can become lazy due to current. Swimming against the flow is stressful, and your guppies will get exhausted. You will find a change in their behavior if the current is too high.
  • Struggle To Find Food: Guppies love food and are always in search of food. Your guppies will find it challenging to find food as they will always be fighting the current.
  • Difficulty In Swimming: Guppies love swimming. The current makes it difficult for your guppies to swim. Due to the current, your guppies require more force to swim against the current. Sometimes, they will get blown away or get pushed all over the place in the aquarium due to excessive current.
  • Lower Immunity: Continuous stress of the current lowers the immunity of your guppies. Lower immunity will make your guppies fall sick often.

Guppies do not prefer strong currents.

So, what steps can you take to reduce the flow in your aquarium so that it does not impact your guppies?

How To Reduce The Current In An Aquarium?

If you find your guppies struggling to swim freely at their own pace, check if the current is too strong in the aquarium.

There are several ways using which you can reduce the current in your aquarium.

Given below are some of the most widely used techniques to reduce the current in an aquarium:

  • Live Plants: Live Plants are an excellent and natural way to reduce the current in an aquarium. You can place live plants in such a way that they block and reduce the water flow in the aquarium. This will help in slowing down the force of the filtered water from the filter. However, ensure that the water from the filter is not entirely blocked as filtered water is essential for guppies’ good health.
  • Right Filter: Choosing the right filter for your aquarium is of utmost importance. You can choose an internal, hang-on, or a canister filter for your guppies’ aquarium. These will allow you to set the flow of the water to be as low as possible. You should always ensure that the filter is not over-sized; otherwise, it becomes difficult to reduce the flow.
  • Airstones And Submersive Pumps: You can place airstones near the aquarium’s surface with a small and adjustable air pump. It will help to minimize the push of water and reduce the current. You can even make use of an air control valve to control the flow of water in your aquarium. Another option is submersive pumps. You can manually turn down the flow rate if they are designed to be adjustable.
  • Manifold Systems: At times, a strong current is only at a particular place in the aquarium where the flow is directed. If you have a strong canister filter with a single water outlet, then the water flow is at any one spot in the aquarium. This means that the water flow is not distributed evenly, and hence current is felt at a particular place inside your aquarium. You can make use of a flexible or ridged plastic pipe so that the water flow is distributed throughout the aquarium. If the water flow is distributed evenly, your guppies will not face the problem of current and can swim freely throughout the aquarium.
