Hygrophila sp. 'Bihar'

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Best suited for the background of large aquariums due to its potential to grow quite large and broad. It needs plenty of space to spread out and display its unique leaf shapes. It can easily overshadow smaller plants if not managed properly.

Botanical form

Stem

The submerged leaves are typically broadly lanceolate and can show a slight reddish tint under strong light. When approaching the surface or grown emersed, the leaves become deeply lobed or pinnate, resembling a completely different plant. The stems are thick and hairy.

Growth

Medium

Exhibits a fast growth rate, quickly growing toward the water surface where its leaf morphology often changes. Frequent trimming is necessary to keep it submerged and within bounds. Its vigorous growth makes it a great nutrient exporter.

Substrate

Medium

Hygrophila sp. "Bihar" produces large, deeply pinnatifid leaves that demand a moderately fertile substrate for optimal health. Planting it in a layer of aqua soil 5 to 7 cm deep accommodates its expansive root network and provides essential macronutrients. While it can adapt to inert gravel with the addition of root tabs, a nutrient-dense bottom ensures more vigorous growth and pronounced leaf shape.

Column fertilization

Recommended

Readily absorbs nutrients from the water column; a comprehensive liquid fertilizer ensures healthy, vibrant growth. It requires a good supply of all essential nutrients to support its large biomass. Iron dosing can help enhance any reddish hues in the upper foliage.

Root fertilization

None

Highly benefits from a deep, nutrient-rich substrate to anchor its large size and support its extensive root system. Adding root tabs is recommended for sustained, vigorous growth. A strong root base is crucial for this robust species.

Trimming

Occasional

Requires regular, aggressive trimming to keep it from taking over the aquarium or growing out of the water. Trimming encourages bushier submerged growth and helps maintain the standard leaf shape. The sturdy tops can be easily replanted.

Propagation

Cuttings

Propagation is simple via stem cuttings; replanting the tops quickly yields new plants. It is a very prolific plant that is easy to multiply. Side shoots will readily form after the main stem is topped.

Sensitivity

Moderate

Generally hardy and adaptable, though it prefers moderate to high lighting and good nutrient levels. It is quite robust and rarely suffers from minor fluctuations in water parameters. It is an excellent choice for a large, dramatic focal point.

Layout role

Midground, Background

Serves as a massive, dramatic background plant or a unique focal point in large tanks. Its variable leaf shape, particularly if allowed to reach the surface, adds significant interest. It provides excellent cover and a wild, natural look to the layout.
