Cryptocoryne parva

Cryptocoryne parva fromac Sri Lanka is the smallest of all Cryptocorynes (only 3-6 cm tall and a roset less than 5-8 cm wide). It is one of the few species that does not significantly change its leaf shape and colour depending on cultivation conditions. It needs more light than most other Cryptocorynes because it almost loses its leaf plate under water. So, it must never be overshadowed by other plants.

Known for its slow growth, but Nutrition Capsules in the bottom layer will enhance the development. Individual plants should be planted a few centimetres apart, and after about six months they will form a cohesive low group of plants.

Very recommendable foreground plant.

Rotala wallichii

Rotala wallichii is a demanding plant that develops red shoot tips in good light conditions.

The most decorative effect can be achieved by planting a large number of stems in a group. Rotala walichii is good as background and midground plant and suitable even for small aquariums, because it is easy to prune if it grows too tall. CO2 addition boosts growth considerably. It also prefers soft, slightly acidic water.

Micranthemum umbrosum

Micranthemum umbrosum is a beautiful plant from US with small round leaves. It is suitable for small or large aquariums with stems becoming 10-25 cm long and 1-2 cm wide. Relatively demanding in terms of light. CO2 addition will promote growth.
Once the plant starts growing, it grows fast, and the shoots need to be pinched out often (can be planted as cuttings in the soil). Most beautiful in groups of many stems.

Glossostigma elatinoides

Glossostigma elatinoides from New Zealand is much in demand in Japanese-inspired aquariums. It is one of the smallest aquarium plants (2-3 cm tall), and thus a good foreground plant. A difficult plant demanding a lot of light. Grows upwards if light is poor. Make sure larger plants do not overshadow it. When planting in the aquarium small clumps (approx. 1/8 pot) should be placed at intervals of a few centimetres to help the plants grow together more quickly. CO2 addition and soft water promote growth significantly.

Rotala rotundifolia sp Blood Red

The Latin name means “the plant with the round leaves”, but this only applies to the marsh variety, which has circular leaves. Rotala rotundifolia from South-East Asia has 15-30 long stems (2-3 cm wide) and long, narrow leaves. Unlike other Rotala species it is relatively undemanding, although it needs good light to produce red leaves.
It forms side shoots willingly, becoming compact and bushy. This also means that it is hard for light to reach the lower leaves, so the plant should be pruned frequently. Also known as Rotala indica.

Height: 15 – 30+

Micranthemum tweediei ‘Monte Carlo’

Micranthemum tweediei ‘Monte Carlo’ originates from Argentina. It has compact, round and fresh light green leaves on creeping stalks and creates a fast-growing carpet in the front of the aquarium.
The plant can grow in light shadow, but requires good light conditions, as well as CO2 additive, in order to develop optimally and become really compact.

Lilaeopsis brasiliensis

Lilaeopsis brasiliensis from South America can grow very compact, but a “lawn effect” (4-7 cm tall) is only achieved at high light intensity. When planting in the aquarium small clumps (approx. 1/8 pot) should be placed a few centimetres apart to help the plants grow together more quickly. Place in an open position without shading from other plants to ensure good light. Lilaeopsis brasiliensis can be used in garden ponds, and also tolerates low salt concentrations in brackish aquariums.
