Which plants would be ideal for the emersed section of my paludarium tank?

Designing a nano paludarium, especially with something as sleek as a DOOA Neo Glass Air, presents a unique opportunity to blend aquatic and terrestrial elements in a compact space. For the emersed section where plants will grow partially or completely out of water, selecting the right species is crucial for maintaining balance and aesthetics. You're correct that Rotala and Anubias can thrive in such conditions. Here are some additional plants that are well-suited for the emersed section of a paludarium:

1. Cryptocoryne spp.

Crypts can adapt to growing emersed and offer a variety of leaf shapes and colors. They're relatively easy to care for and can add depth with their lush foliage.

2. Microsorum pteropus (Java Fern)

While commonly used fully submerged, Java Fern can also grow emersed, as long as its roots are kept moist. It’s a hardy plant that attaches well to rocks and wood.

3. Bucephalandra spp.

Similar to Anubias, Bucephalandra is versatile and can grow attached to hardscape materials. It thrives in humid conditions with its leaves out of the water.

4. Mosses

(e.g., Java Moss, Christmas Moss) - Mosses can grow beautifully in the emersed section, providing a lush, green carpet. They require high humidity to thrive.

5. Pilea spp. (e.g., Aluminum Plant)

This terrestrial plant enjoys the high humidity of a paludarium and can add a different texture and color with its unique foliage.

6. Ficus pumila (Creeping Fig) - A vigorous grower, it can cover backdrops quickly with its small, heart-shaped leaves. It needs trimming but creates a stunning green wall effect.

7. Hemianthus callitrichoides (Dwarf Baby Tears)

While challenging, it can grow emersed with adequate humidity, creating a bright green, carpeted look.

8. Hygrophila spp.

Certain species can adapt to emersed growth, offering a range of leaf shapes and sizes. They're generally easy to care for and can grow quickly.

9. Ferns (e.g., Small varieties of Ferns like Bolbitis)

These can adapt to partial submersion and add a delicate texture to the landscape.

For success with these plants in a nano paludarium, consider the following tips:

- Humidity: Keep the humidity high to support the emersed plants, especially those not used to being out of water.

- Lighting: Ensure adequate lighting for both the aquatic and emersed plants, considering their individual needs.

- Water Circulation: Good circulation helps maintain humidity and health of the plants but avoid strong currents that could disturb smaller species.

- Fertilization Use a balanced, slow-release fertilizer in the substrate for the emersed plants and consider liquid fertilizers for the aquatic section.

Remember, the key to a thriving paludarium is balancing the needs of both aquatic and terrestrial plants, along with ensuring the inhabitants (if any) are compatible with the environment you're creating.
