Cryptocoryne Undulata Broad Leaf is a red version of Cryptocoryne Undulata originally from Sri Lan...Cryptocoryne Undulata Broad Leaf is a red version of Cryptocoryne Undulata originally from Sri Lanka. This easy-to-grow aquarium plant is highly adaptable, with its final appearance depending on light and nutrient levels. Under low light, it produces taller, greenish-brown leaves, while higher light and added CO2 promote faster growth with shorter, reddish-brown leaves. Tropica 1-2-Grow plants are tissue-cultured in a laboratory, ensuring they are free from snails, algae, and pesticides, making them safe for sensitive shrimp and fish. These compact plants can be divided into smaller portions to cover larger areas, ensuring dense and healthy growth in small to medium aquariums.
The Tropica Cryptocoryne Undulata Broad Leaf is an ideal choice for both novice and experienced aquarium hobbyists looking for a versatile, mid-ground plant that adds texture and color to a scape. This tissue-cultured specimen provides the significant benefit of being completely free from pests, algae, and pesticides, making it perfectly safe for delicate shrimp and sensitive fish; however, users should be aware that the plant's appearance, specifically leaf color and height, will vary significantly depending on lighting intensity and CO2 injection levels.

FAQs
Does this plant require CO2 injection?
No, it is highly adaptable and will grow in low-tech setups, though it will grow slower and exhibit greener colors compared to high-tech tanks.
Can I plant this directly into sand?
While it can grow in sand, you must provide root tabs as the plant primarily feeds through its root system and will struggle in inert sand without supplemental nutrients.
Why is my plant melting after planting?
This is 'Crypt melt,' a standard reaction to new water chemistry. As long as the crown and roots remain firm, keep the plant in place, and it will bounce back.
Is this plant safe for my Neocaridina shrimp?
Yes, Tropica 1-2-Grow plants are specifically cultured to be free of pesticides, making them some of the safest options for shrimp tanks.
How do I make the leaves turn red?
Higher light intensity and consistent CO2 injection are the primary factors that trigger the development of red pigments in the leaves.
Troubleshooting
Leaves turning translucent and disintegrating (melting)
This is common for Cryptocorynes during adjustment. Ensure the roots are healthy and stable; do not pull the plant up, as it will regrow from the root system.
Plant growth is very slow or leaves are reaching too high
Increase light intensity or duration to encourage more compact, reddish growth. Check that there is sufficient root nutrition via soil or root tabs.
Pros and Cons
Pros
Completely free of snails, algae, and pathogens
Highly adaptable to different tank parameters
Ideal for sensitive shrimp-only tanks
Easy to divide and spread during planting
Attractive color variation based on lighting
Cons
Growth habit is inconsistent without controlled lighting
May undergo 'melting' when first transitioning to a new environment
Requires patience to reach full color potential
Setup, Compatibility & Care
Preparation: Carefully remove the plant from the pot and wash the nutrient gel off the roots under lukewarm running water.
Division: Use sterile tweezers or sharp scissors to split the clump into 3-5 smaller portions to maximize coverage.
Planting: Use aquascaping tweezers to insert the roots into your substrate (aquarium soil is recommended) at least 2cm deep.
Acclimation: It is normal for some of the original leaves to die off (melt) as the plant adjusts to your water parameters. Leave the roots planted; new, healthier leaves usually emerge within 2-3 weeks.
Maintenance: Trim older, outer leaves periodically to encourage new growth from the center of the crown.
