African dwarf frogs are very interesting species that many people want to have in their aquariums. These frogs, that grow to up to 3 inches, are not only suitable for smaller tanks, but they are also perfect for community tanks.

They are very peaceful and will get along well with many other peaceful fish species and other peaceful animals.

If you want to keep an African dwarf frog, then there are some things that you must take care of before you own one (or more).

Of course, it is good if you know some things about this species, like what food it likes to eat, what are the requirements of the frog, but arguably one of the most important things is providing the right filtration for the water in the aquarium.

The majority of these specifications are covered in my other article about the African dwarf frogs.

In this article, however, we will focus on which filters are best for aquariums with African dwarf frogs in them.

African dwarf frogs are small creatures, and they like to swim around the water and up to the water surface. They are slow swimmers, and their size makes it easy for them to get carried away by strong currents.

Make sure that you choose an adjustable flow filter because you don’t want a strong water flow.  African dwarf frogs are not very good swimmers, which means that they can get carried away by strong currents.

With this in mind, I have compiled some of the best filters available with this feature that would be suitable for a tank with the African dwarf frog in it. Let’s take a look at the seven best filters for African dwarf frogs.

1. Aqua Clear – Fish Tank Filter

Why You Should Use Water Filtration?

Filters are absolutely essential tools to have if you have an aquarium, independent on the size of the tank, and whether the tank is freshwater or marine tank.

Filtration is the process of eliminating waste products and unwanted chemicals from the water, and replacing them with clean water without the waste and with beneficial chemicals and also to promote beneficial bacteria growth.

Without a filter, your water would be full of chemicals, debris and unwanted material that accumulates in a matter of weeks, if not days.

For this reason, it might be wise to consider this matter thoroughly and delve deep into it. Because a good filter will last you a long time and also provide you with a very good filtration system.

Spending a bit more on a good filter from the start is often recommended to beginners, as a good filter can save you a lot of money, but also a lot of time and your bad mood in the long run.

Most filters offer three-stage filtration, which is necessary for good filtration of your tank water – biological, mechanical and chemical filtration.

Mechanical filtration gets rid of big particles of debris, the chemical gets rid of waste chemicals in the water, and biological is necessary to provide the good bacteria and chemicals to the water.

There are also more types of different filters that you can buy. You can buy power filters, internal filters, and filters that are made specifically for marine aquarium systems. In this list, we focused mostly on internal and power filters.

Do African Dwarf Frogs Like Strong Water Flow?

African dwarf frogs are small and quite fragile creatures. They are quite small, as they grow to a maximum 3 inches in size. This means that they can get carried away by strong water flow very easily.

Not only this, but African dwarf frogs are not very good swimmers. You need to consider their need to swim around the water a lot and actually come close to the surface as well. They tend to swim very slowly.

All these attributes of the African dwarf frog make it necessary to buy a filter with adjustable water flow. With this feature, you will be able to adjust the strength of the water flow. Which will make it easier for you to adjust the flow and slow it down so that the frogs will be able to swim.

 So in short, the answer to the above question is, no. African dwarf frogs do not like strong water flow. And you should find a way to reduce the strength of it.

Fortunately, many filters out there offer this option to adjust the flow rate while not compromising on the quality of filtration at all. And the list in this article focuses on filters with this feature included.

How to Reduce Water Flow in Your Filter?

This can be done easily if your filter has the option to adjust it, of course. Many of the filters on the list have a knob where you can adjust the water flow coming out of your filter.

With this knob, it is easy to see and know if the water current is too strong or not. If you do not know where to locate this knob or how to reduce the water flow, you will have to read a manual included in the package of the filter, where you can learn all about this feature.

Once you locate the knob, you should reduce the water flow to make it appropriate for African dwarf frogs. You will be able to see if the current is too strong by the behavior of the frogs. They will be unwilling to swim in such water and will get carried away by it.


African dwarf frogs are lovely little creatures. They can make any aquarium more interesting just by their presence and behavior. Peaceful, low-maintenance and interesting to look at, they are a popular choice amongst the fish tank keepers out there. They can be kept in a group or alone. Depending on the specifications of your tank.

Questions and Answers

Fair warning, I own the no.17 submersible filter and it is pretty powerful even on its lowest setting. I bought that one for my 2.5 gal tank and it killed my guppy. I then moved it to the 10 gal tank and it still has a pretty damn strong current.
I highly recommend AGAINST getting that filter for delicate, slow swimmers. It’s fine in the 10 gal, but not for anything smaller.
