What Is a Paludarium?
A paludarium is a hybrid enclosure that combines both land and water, making it the perfect environment for dart frogs, fish, aquatic plants, and terrestrial greenery.
Typically, a paludarium consists of:
✅ 70% land – a humid, jungle-like terrain for frogs and plants
✅ 30% water – a small pond or stream for fish and aquatic life
The trick to a great paludarium is seamlessly blending both environments. Ready to build yours? Let’s get started!
Step 1: Choosing the Right Tank
Your paludarium’s foundation starts with the right enclosure. Here’s what to consider:
✔️ Size: A 20-gallon tank is the minimum, but bigger is better for stability.
✔️ Shape: Tall tanks work best for dart frogs since they love to climb.
A vertical terrarium is ideal.
✔️ Front-Opening Access: Makes maintenance much easier!
✔️ Ventilation: Proper airflow prevents mold and maintains humidity. Many Exo Terra tanks have built-in ventilation.
Step 2: Creating the Land-Water Divide
One of the most challenging parts of a paludarium is keeping land dry while maintaining a healthy aquatic section. Here’s how to do it:
False Bottom – Use egg crate light diffusers covered with fine mesh to allow water drainage.
🔹 Drainage Layer – Add LECA (expanded clay balls) or aquarium gravel to prevent water from soaking the soil.
🔹 Substrate Barrier – A mesh screen prevents the soil from clogging the drainage.
🔹 Natural Slope – Arrange rocks, driftwood, or foam backgrounds to create a gradual transition.
Step 3: Choosing the Best Substrate
A healthy substrate does more than look nice—it supports beneficial bacteria and tiny cleanup critters like springtails and isopods.
🔸 Perfect Bioactive Substrate Recipe: ✔ 40% organic potting soil (chemical-free)
✔ 30% coconut fiber
✔ 20% sphagnum moss
✔ 10% orchid bark
🔹 Pro Tip: Top it off with leaf litter to mimic the forest floor and keep humidity stable.
Step 4: The Aquatic Section—Filtration & Water Care
Keeping water crystal clear is crucial, as paludariums hold less water than regular aquariums, making them prone to waste buildup.
🔹 Best Filter Options: ✔ Small Canister Filter
✔ Hang-On-Back Filter
🔹 Water Changes: 20% per week keeps ammonia and nitrites in check.
🔹 Water Testing Kit: Monitor pH, ammonia, and nitrates regularly.
Step 5: Choosing Fish for Your Paludarium
Not all fish are frog-friendly! Stick to small, peaceful species that thrive in similar conditions.

Step 6: Best Plants for a Thriving Paludarium
Aquatic Plants: ✔ Anubias: hardy, slow-growing, attaches to driftwood
✔ Java Fern (👉 Great deal on Amazon): low-maintenance, lush green leaves
✔ Cryptocoryne (👉 Variety pack available): Adds color and texture
Terrestrial Plants:
✔ Bromeliads: Frogs use them for laying eggs
✔ Mini Orchids: Beautiful and thrive in humidity
✔ Moss & Ferns: Help retain moisture
Planting Tip: Attach orchids & air plants to driftwood using aquarium-safe glue.
Step 7: Lighting & Humidity—Keeping It Perfect
🔆 Lighting: ✔ Low-output UVB bulbs (2-5%)—essential for dart frogs
✔ LED Plant Lights: Boost plant growth (👉 Best LED plant light)
💦 Humidity:
✔ Keep levels at 70-80%
✔ Automated misting system
✔ Monitor humidity with a digital hygrometer
Step 8: Feeding Your Dart Frogs & Fish
🐸 Dart Frog Diet: ✔ Live fruit flies
✔ Calcium-dusted insects
🐟 Fish Diet: ✔ High-quality flakes & pellets
✔ Occasional frozen treats like bloodworms
