Shoreweed

Isoetes lacustris, commonly known as Lake Quillwort, is a unique, ancient lycophyte featuring stiff, dark green, quill-like leaves. It grows very slowly from a corm-like base and is best suited for cool-water aquariums with soft water and clear conditions. Because of its remarkably slow growth, it is susceptible to algae if lighting is excessively high without adequate balance.

A highly unique, slow-growing species of filamentous green algae that naturally forms into velvety green spheres. Native to cold water lakes, it thrives in cooler aquariums and is a favorite among shrimp keepers due to the immense grazing surface it provides.

Süßwassertang is a unique aquatic plant that is actually the gametophyte (prothallium) stage of the fern Lomariopsis lineata. Treated functionally as a moss or liverwort in the aquarium hobby, it forms dense, beautiful mounds of translucent, ribbon-like thalli. It is extremely undemanding, adaptable, and thrives in low-tech setups. Because it does not root, it is typically tied or glued to hardscape, or allowed to sink and settle in low-flow areas. It is highly valued by breeders for providing an exceptional grazing surface and dense refuge for shrimp and fry.

Barclaya longifolia, commonly known as the Orchid Lily, is an elegant bulbous aquatic plant native to Southeast Asia. It features long, undulating, ribbon-like leaves that can display striking shades of olive green to vibrant red, often with bright pink or red undersides. Known for its delicate foliage, it requires a nutrient-rich substrate and may occasionally enter a natural resting phase where it sheds its leaves. It is highly prized by aquascapers for midground to background placement but needs protection from herbivorous fish and snails due to its highly palatable, fragile leaves.

Cryptocoryne pontederiifolia is a robust, broad-leaved rosette plant native to Sumatra. Known for its distinct ovate, light green leaves that can sometimes exhibit a pinkish hue on the underside, it is a hardy and adaptable species. It makes an excellent midground to background plant in the aquarium. Like many Cryptocoryne species, it establishes an extensive root system and thrives best when provided with a nutrient-rich substrate, eventually forming dense thickets via runners.

Glossostigma elatinoides, commonly known as Glosso, is a classic and highly popular aquarium carpeting plant native to the swamps and bogs of Australia and New Zealand. Prized for its ability to form a dense, bright green mat along the aquarium floor, it is often a centerpiece in high-tech nature aquariums. It is a demanding plant that requires intense lighting and carbon dioxide supplementation to creep horizontally; without these, it tends to grow leggy and vertical. Frequent trimming is necessary to prevent the carpet from overgrowing itself, which can lead to the lower layers dying off and the mat detaching from the substrate.
