Care notes
This moss prefers cool water (15-24°C) but tolerates higher temperatures up to 26°C. Low to moderate lighting is suitable. CO2 is not needed. A pH of 6 to 7.5 and low to medium hardness are ideal. It attaches easily to decorations. Regular trimming keeps it compact. It can be grown floating. Avoid excess nutrients to limit algae.
