Species description
Geographical Origin and Habitat: This species originates from South America, where it grows along the humid banks of rivers, marshes, and temporarily flooded soils. It is accustomed to living both in emersed environments with high humidity and completely submerged during seasonal floods, showing excellent tolerance to environmental fluctuations.
Taxonomy & Genetics: It belongs to the family Rubiaceae, a plant family uncommon in the aquarium hobby but which includes well-known terrestrial plants such as coffee. The specific affinity with 'kuntzei' is indicated by 'cf.' (compare to) due to uncertainties in the exact cataloging of aquatic species of the genus Diodia.
Physical Structure: It is an erect or prostrate stem plant. The stems are thin but flexible and bear leaves arranged in opposite pairs along the nodes. Under the water surface, it develops a branched structure that tends to form dense bushes if pruned regularly. The height typically ranges between 20 and 40 cm.
Color & Texture: The leaves have an olive-green or forest-green hue. Under strong lighting and with a good supply of nutrients, the stems and upper leaves can develop interesting bronze-reddish tones. The leaves are lanceolate, soft to the touch, and have a smooth surface.
Care, breeding and tankmates
Lighting & CO2: Requires moderate to intense lighting. If the light is weak, the internodes stretch excessively and the lower leaves risk falling off. The addition of CO2 is highly recommended to support healthy growth and to obtain more intense colors.
Nutrition & Substrate: Needs a good nutritional intake both through the roots and in the
Water Chemistry: Prefers temperatures between 20°C and 30°C. It adapts to neutral or slightly acidic pH values (6.0 - 7.5) and requires medium-low water hardness to prevent stem rigidity and leaf fragility.
Space Management & Placement: The best placement is in the midground or background of the aquarium, planted in small spaced groups. It should not be positioned too close to other ultra-fast growing stem plants that could easily shade it.
Pruning: It is pruned like most stem plants: by cutting the top above a node and replanting the cut part in the substrate. This operation encourages the development of lateral shoots from the remaining stem, creating a bushier and more compact clump.
Risks & Diseases: The main risk is the loss of basal leaves due to poor light penetration or macroelement deficiencies. Additionally, the stems can rot at the base if planted too close to each other, limiting water flow.
