Tropica Sagittaria subulata CUP

The little arrowhead is reminiscent of grass, it forms dense stands in good light conditions and is therefore suitable for the natural design of the foreground and middle ground. It is one of the best known and "oldest" aquarium plants, but if there is an excess of macronutrients it can shoot up over 30cm. It is not uncommon for it to have long flower stalks just above the surface of the water and develop small, white flowers.

• Light requirement: low, but sufficient (according to grower 0.5 watt / litre)
• Optimal temperature: adaptable (from 4 to 30°C)
• Water values: very adaptable (also tolerates very hard water)
• CO2 requirement: medium (according to the breeder, the average requirement is 6 to 14 mg/litre)
• Nutrients: Iron deficiency can be felt through white leaves
• Propagation: runners

Our expert Oliver Knott recommends:
Since Sagittaria subulata is undemanding, it fits perfectly into "technology-free" tanks without CO2 supply or intensive lighting. But be careful: it forms runners and these can easily overgrow smaller plants.

Note: The cups are grown in the laboratory. Aquatic plants from the so-called in vitro culture are grown sterile. They are therefore also suitable for sensitive animals such as dwarf shrimp and can be used immediately. With in vitro plants there are no stowaways such as snails or parasites, and pesticides are also completely avoided.
