Mayaca Fluviatilis (Mayaca fluviatilis) — medium light, 22-28 °C, pH 5.5-7, no CO2.
Compiled by Aquairi from published sources · Published · Updated
Overview
Mayaca Fluviatilis (Mayaca fluviatilis) is a fine needle-leaved plant of the family Mayacaceae, grown as an aquarium plant. A delicate stem plant with very fine, needle-like leaves arranged spirally around the stem. Creates an ethereal, feathery texture in the aquarium. Under high light, leaf tips may develop attractive red coloration. Prefers soft, slightly acidic water.
Taxonomy
- Family: Mayacaceae
- Genus: Mayaca
- Scientific name: Mayaca fluviatilis
- Common synonyms: Stream Bogmoss, Mayaca fluviatilis
Habitat
Mayaca fluviatilis originates from South America, North America, where it grows in freshwater marshes, ditches and slow-moving streams, frequently emersed on seasonally flooded ground.
Growth requirements
- Lighting: medium
- CO2: not required
- Temperature: 22-28 °C (72-82 °F)
- pH: 5.5-7
- GH: 1-8 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 30 cm
- Growth rate: medium
- Nutrient demand: medium
- Recommended placement: background
- Typical trim interval: 14 days
Placement
In aquascapes this plant suits the background.
Propagation
Propagation is by stem cuttings replanted into the substrate; daughter plants are separated once they have formed several leaves and visible roots.
Common issues
Pale or stunted new growth usually signals a nutrient or iron deficiency, while algae on older leaves often follows light that exceeds the available nutrients or CO2; correcting fertilisation and trimming affected parts resolves most cases.
Propagating Mayaca fluviatilis (Stream Bogmoss) from Cuttings
Overview
Mayaca fluviatilis, often sold as stream bogmoss, is a perennial submerged stem plant with soft, thin leaves arranged spirally around pale green to whitish stems that can grow up to a meter long. Its needle-fine foliage gives an airy, moss-like texture, and under strong light the tips can take on red tones. It favours soft, slightly acidic water but also adapts to medium-hard conditions.
Because the species is grown as a bunch plant and the commercially traded form is typically sterile, cuttings are the practical and reliable way to multiply it in the aquarium.
Propagation Method (Cuttings)
Propagation is done by topping: cut the top portion of a healthy stem and replant it, while the remaining base regrows. Stem fragments as small as 2 cm can establish into new plants, so even short trimmings are usable. Where you cut, the parent stem responds by forming two new side shoots, which is how dense, lush bushes are built up over time.
Step-by-Step
- Select a healthy, vigorous stem with dense green growth.
- Cut the top 5-10 cm (or longer) cleanly with sharp scissors.
- Strip the leaves from the lowest 2-3 cm so they will not rot in the substrate.
- Push the bare stem section gently into nutrient-rich substrate.
- Space several cuttings a little apart rather than crowding them.
- Leave the parent base in place; it will branch into new shoots from the cut.
Conditions for Healthy Growth
Modest lighting is enough to keep the plant alive, but it grows best with strong light and added CO2, where it can put on noticeable length each day. In low light it tends to stretch, look leggy and slowly fade. Use a nutrient-rich substrate; iron in particular matters, since pale yellow or white shoots signal iron deficiency. Keep water soft and slightly acidic for the best colour and texture.
Trimming & Maintenance
Under high light and CO2 the plant grows fast and needs frequent trimming, roughly every couple of weeks, to stay bushy and within bounds. Avoid planting bunches too densely, as shaded lower stems and leaves can melt away. Regular topping both shapes the group and produces fresh cuttings.
Common Challenges
The most common problems are leggy, fading growth in insufficient light, lower-stem melt when planting is too dense, and pale shoots from iron or nutrient deficiency. Left untrimmed in ideal conditions it can grow vigorously and quickly dominate a tank, so steady maintenance is key.
