About Eriocaulon 'Blood Vomit'

Eriocaulon 'Blood Vomit' is a highly unusual and sought-after aquarium plant known for its compact rosette growth and deep red to burgundy colouration under strong aquarium lighting. Its fine, narrow leaves form a dense, architectural clump that makes it an excellent focal plant for aquascapes.

Like many Eriocaulon varieties, it is considered a demanding plant and performs best in soft, acidic water with strong lighting, consistent CO₂ and nutrient-rich substrate.

Its compact growth makes it particularly effective as a foreground or midground feature, where the intense colour can contrast beautifully with green aquarium plants.

Common Mistakes

Adding it to a low-tech aquarium
This plant performs best under strong lighting with CO₂ and stable parameters.

Planting the crown too deeply
Keep the central growing point above the substrate to prevent rot.

Sudden changes in water chemistry
Eriocaulon can be sensitive to rapid changes, particularly while establishing.

Poor root nutrition
Use a quality nutrient-rich substrate or appropriate root fertilisation.

Insufficient light
Strong lighting is important for maintaining compact growth and encouraging stronger colouration.
