Aquatic Frog in Tank

How to Set Up an Aquatic Frog Tank

Aquatic frogs are among the most popular amphibians kept as pets. They’re easy to take care of, great for beginners, and require very little upkeep. Not only that, getting an aquarium and buying the frogs is fairly cheap. That is exactly what this step-by-step guide is for; setting up an aquatic frog aquarium.

Before we get into the build, I will start by emphasizing one thing; this guide is not for a specific aquatic frog. This build is suitable for African Dwarf Frogs and even African Clawed Frogs. If you’re not familiar with their needs, the first things you should do is learn about the frog you want to keep.

Chances are, the frogs available at the local pet store are African Dwarf Frogs. They’re small frogs, with webbed front and back feet and have eyes on the side of their heads. The African Clawed Frog is very similar in appearance. So similar, in fact, that they’re often mislabeled at pet stores. Anyway, the clawed frogs don’t have webbing on their front feet. They have 3 independent digits. Also, their eyes are on top of their heads. I’ve created care sheets for both and you can find them in the frog care sheets section of this website.

Basic Tank Setup for Aquatic Frogs

When setting up a tank for an aquatic frog, the most important aspect is the water. Amphibians have semi-permeable skin which means they absorb things through their skin. It’s because of this reason that the water needs to be clean, free of toxins and dechlorinated. I talk more about water in the final step of this guide. The second most important part is the size of the tank. I recommend a 10-gallon minimum, plus an additional 5 to 10-gallons per frog.

Aside from the tank, you’ll need a water heater if you’re keeping African Dwarf Frogs. African Clawed Frogs do a little better at room temperature but both need a nice day and night-time light schedule. They actually don’t require lighting, but it’s always a good idea for tanks that are placed in rooms with little or no sunlight from windows. Anyway, here is a step-by-step guide for setting up an aquatic frog tank.

Step 1: Picking an Aquarium

Fluval Flex Aquarium

The aquarium used in this setup is a Fluval Flex.

When selecting the perfect aquarium, there are 2 main aspects that come into play. How big the tank is and how much it costs. Luckily, there are a handful of companies competing to make the best aquariums for the lowest prices; finding a cheap aquarium is the easy part. Whether you look online or at the pet store, there are plenty of options.

The size is important. While the width and depth of the tank can be as large as you want, the height should be no more than 12″. African Dwarf Frogs actually surface to breathe air and because of this, it’s suggested that the standard 12-inch tall tanks are all you should use. As for the overall size; 10-gallons minimum with an additional 5 to 10-gallons per frog. If you have 2 or 3 frogs, you should get something between 20 – 30-gallons. Again, you can go larger if you want, so long as its no more than 12 inches in height.

So, now that we know the correct size of the enclosure, let’s touch on another topic; aquarium kits. You might not need a light and you may refuse to use a water filter but you should certainly use a water heater, at least for ADFs (African Dwarf Frogs). A light may be needed if you’re putting the frog in a room with little or no natural light from windows. The filter can be used to help clean the water. Since you probably need a light, heater, screen lid, and water filter, you might consider getting an aquarium kit to save money in the long run. Listed below are my favorite kits.

Once you’ve got your aquarium, place it in the spot you want to keep it. Once you’ve added the water, it will be extremely heavy and hard to move. Finally, give the tank a quick wipe down to make sure the glass is clean.

Step 2: Install the Heater

Water Heater for Aquarium

Because the average water temperature should remain around 78 degrees Fahrenheit, an aquarium heater is recommended. How you install this largely depends on the brand of heater you have. Some are designed to be positioned vertically while others horizontally. Read the instructions for your specific model for more information.

Be sure to not turn the heater on until the tank is filled with water. Also, it’s very important to install a drip-loop to keep water from reaching power outlets.

Step 3: Add Fake Plant Decorations

Fake Plants

The next step on our tank set-up is to place the artificial plants in place. This really comes down to personal preference but my only suggestion is to try and hide the water heater with one or more of the plants.

If you’re wondering why we add these before the gravel, its because most fake plants are designed to sit beneath the substrate. If your fake plants are designed for that, you should go to step #4 before adding your plants.

Friendly Tip: You can get fake plants on Amazon for less than half the cost at most commercial pet stores. Click here to see them.

Using real plants is a great option too. Because I’m not qualified to teach you how to keep real plants alive in an aquarium, I’m not suggesting it here. However, if this something you’re interested in, I encourage you to use live plants but find someone who knows more about this subject than me.

Step 4: Add the Substrate

Aquarium Substrate

Aquatic frogs have been known to accidentally eat small gravel substrates, which can lead to impaction. Not only that, juvenile aquatic frogs can easily get trapped between the large gravel. So as you can imagine, you’ll need to be a little picky and find a nice medium-sized gravel. Or simply avoid rocks all-together and use a different substrate. Listed below are some substrate options with low impaction risk.

  • Pieces of slate
  • River rocks (not too large)
  • Marine sand
  • Bathroom Tile

If you happen to choose sand, go with a marine-grade sand to be safe. Many of them have high levels of calcium carbonate, which will affect the pH level of the water. Also, allow the water to settle overnight if possible.

Step 5: Finish Setting up the Decorations

Aquarium Decoration Rocks

One of the most important features of an aquatic frog setup is the ‘hides’. Hides include logs, plants, rocks, decorations, and other items suitable for giving your pets a hiding place. Provide at least 2 different hiding places. If possible, provide 3 or 4; some small and some large.

I’ve seen people using clay garden pots to create hiding places, and they worked great. You can spend as much or as little as you want, it’s entirely up to you.

Step 6: Fill the Tank with Water

Pouring Water into Aquarium

The final step is to fill the tank with clean, dechlorinated water. Amphibians need toxin free water to remain happy and healthy. If you’re not familiar with this, please read this safe water guide for amphibians. I recommend using a water conditioning agent with tap-water. It’s just the fastest, easiest way to fill an aquarium and ensure the water is suitable. My favorite is ReptiSafe but there are several other options available online and in pet stores.

One of the best methods for filling a tank with water and not messing up the plants, decorations, and the substrate is to place a dinner plate on top of the substrate; gently pour the water on top of the plate until there is 4 – 5 inches of water in the tank. At that point, it’s safe to remove the plate and fill the rest of the tank with water. Be mindful of your decorations so you won’t have to come back and adjust them later.

Introducing Your Frog to the Aquarium

Once finished, I suggest letting your aquarium sit overnight. This allows everything to settle down in the water and allows it to become room temperature. Before placing your frogs into their new home, turn on the water heater long enough for the water to reach the desired temperature. For African Dwarf Frogs the sweet-spot is right around 78 degrees Fahrenheit. As for African Clawed Frogs, they prefer the water temperature around 72 degrees.

Get a sandwich bag or a plastic container and fill it with the water your frog is currently in. If you’ve just purchased the aquatic frog(s), they’re likely already in a plastic bag. If not, get the frog into the bag and gently place the bag inside the new aquarium. Let them adjust to the temperature of the water in the new aquarium. Once they’ve had time to acclimate, you can release them into their new home.

One last thing, don’t forget to place a screen cover on the top of the aquarium. Even though these frogs are in the water, they can still jump out. I hope this guide was helpful to you! If so, please consider sharing it with your friends and family on social media.

Questions & Answers

  • Keldon

    We have two ADF in our fish tank that we have from a friend. And today we found one of our ADF trying to eat the EEL that was in our tank. We are feeding them with the rest of the fish tank just like our fiend told us to do. But is our frogs missing some kind of food and do they tend to eat the fish in the tank with them?

  • Nicole C

    I have an ADF that I originally purchased for my daughter. As it normally goes, I am parent to the frog also. We realized he’s been part of our family for 7 years now. What is their avg life expectancy?

    • John

      Hey Nicole! It’s hard to say exactly how long your ADF will live. Many keepers claim 5 years is the average but that’s a misleading answer. A better estimate is around 10 years in captivity but their lifespan is subject to how well you take care of them. The frog’s genetics play a role in this, too.

      I did some research on this topics and discovered the lifespan of an ADF varies greatly. Many keepers report 5 years is average while others report 12 years. Having said that, there are claims of African Dwarf Frogs living 20 + years. I hope this helps to answer your question 🙂
