Product description

Cryptocoryne wendtii, often called Wendt's Water Trumpet, is a popular and versatile aquarium plant known for its hardiness and range of leaf colors. It's a great choice for both beginners and experienced aquarists due to its adaptability to various conditions. 

Here's a guide to caring for Cryptocoryne wendtii:

1. Planting

Substrate: Cryptocoryne wendtii are primarily root feeders, meaning they absorb most of their nutrients from the substrate.

They thrive in a nutrient-rich substrate like aquarium soil or fertilized gravel.

If using inert substrate (like sand or plain gravel), it's essential to supplement with root tabs to provide necessary nutrients.

Planting:

Create a small hole in the substrate.

Carefully place the roots into the hole, ensuring the crown (base of the leaves) is above the substrate.

You can trim the roots slightly to make planting easier.

If the plant struggles to stay anchored, try planting at an angle or using a plant weight. 

2. Lighting

Cryptocoryne wendtii prefers low to moderate light.

It can tolerate a range of light intensities, but excessive light can lead to algae growth on the leaves.

Aim for 8-10 hours of light per day using full-spectrum aquarium lights or specialized plant lights.

Low light levels can result in taller, more elongated leaves, while moderate lighting can promote a more compact, bushy growth.

Floating plants can help shade Crypts if your lighting is too intense. 

3. Water parameters

Temperature: 72-82°F (22-28°C). Some sources suggest a slightly wider range of 68-82°F or even 77-86°F.

pH: 6.0-7.5.

Hardness: 2-15 dKH (moderately soft to moderately hard). 

4. Fertilization

Cryptocoryne wendtii benefits from regular fertilization, especially since they are root feeders.

Use a liquid fertilizer or root tabs that provide essential nutrients like nitrogen, phosphorus, and potassium, as well as trace elements. 

5. Maintenance and propagation

Water changes: Regular water changes (20-30% weekly) help maintain water quality.

Pruning: Trim yellow or decaying leaves to keep the plant healthy.

Propagation: Cryptocoryne wendtii spreads via runners with plantlets that can be separated and replanted, or by gently dividing the plant into sections with roots and leaves. 

6. Avoiding "Crypt melt"

Sudden changes in conditions can cause "Crypt melt," where leaves disintegrate.

Maintain consistent water parameters, lighting, and temperature to prevent this.

If melting occurs, the plant's roots will likely recover and grow new leaves. Remove melted leaves to prevent ammonia spikes and algae. 

Additional tips

CO2 injection can enhance growth and color, but is not required.

Crypts prefer low to moderate water flow.

Choose tank mates carefully, as some fish may uproot or damage Crypts. You can use rocks or pebbles to help secure the plant.
