Flame Moss

Flame moss is a moss that grows its branches vertically rather than horizontally, with a slight twist. When the dark green shoots curl and stretch upward, they resemble tongues of flame, which is where its name comes from. This upright growth adds a vertical texture and movement to roots and rocks that other mosses cannot provide.

It is considered to belong to the same genus as Java moss, but its exact species identity has not been determined. It is easy to care for and adapts to anything from cool water to tropical temperatures. It is often used in shrimp tanks and natural-looking layouts.

• Tie it loosely to rocks or roots in small clumps, at the base of the shoots.
• Do not wrap the top tightly so the shoots can grow upright; securing only the base is enough.
• It looks good in the foreground and midground, on top of rock groups or at the tips of roots.

• Light: low to medium. In very low light the shoots become loose and pale.
• CO₂: not required but supports growth.
• Fertilizer: liquid fertilizer and fish waste are enough.
• Trimming: rarely needed; cut overly long shoots at the base.
• Flow: strong flow flattens the shoots; choose a calm spot.

Propagate by separating shoots at the base and tying them to other rocks or roots. Over time the clump spreads by producing new shoots from its base.

• Algae: thread algae can settle between the shoots; cut out the affected part and reduce the light.
• Shoots lying flat: too much flow or not enough light.
• Browning lower parts: the clump is too dense; thin it by separating a few shoots.
