Cuphea anagalloidea is a unique aquatic plant that has gained attention in the aquarium hobby for its striking appearance and specific care requirements. Here’s a detailed overview of its characteristics, origin, light and water conditions, and planting instructions.

Origin

Cuphea anagalloidea is endemic to Brazil, specifically found in the northern, eastern, and southeastern regions, including states like Pará, Tocantins, Bahia, Goiás, and Minas Gerais. It belongs to the family Lythraceae and is one of the few aquatic species within the genus Cuphea, which comprises approximately 260 species primarily distributed across the American tropics and subtropics12.

Light Conditions

This plant thrives under strong lighting conditions. The intensity of light significantly affects its coloration; under optimal lighting, the upper side of its submerged leaves displays a vibrant red hue that can appear as if it has been brushed on. In lower light conditions, the color may not be as pronounced1.

Water Conditions

Cuphea anagalloidea prefers soft to moderately hard water with a slightly acidic to neutral pH range. While specific water parameters are not extensively documented, like many aquatic plants, it benefits from stable water conditions that mimic its natural habitat2.

How to Plant

To successfully cultivate Cuphea anagalloidea in an aquarium:

1. Substrate: Use a nutrient-rich substrate to support its growth.
2. Planting Depth: Plant the stems upright in the substrate, ensuring that the base is covered while leaving some leaves above the substrate.
3. Propagation: This plant can be propagated through top and lateral cuttings. Cuttings should be taken from healthy stems and replanted in suitable conditions.
4. Maintenance: Regular trimming will help maintain its shape and promote bushier growth.

In summary, Cuphea anagalloidea is a visually striking aquatic plant that requires strong light and stable water conditions for optimal growth. Its propagation is straightforward through cuttings, making it a desirable choice for aquascaping enthusiasts looking to enhance their underwater landscapes with vibrant colors.
