Myriophyllum Guyana care guide
Myriophyllum Guyana (Myriophyllum sp. 'Guyana') — high light, 22-28 °C, pH 5.5-7, CO2 recommended.
Overview
Myriophyllum Guyana (Myriophyllum sp. 'Guyana') is an aquatic plant of the family Haloragaceae, listed in the Aquairi knowledge base as an intermediate-level species. It is typically grown under high light with pressurised CO2 injection on any substrate. Delicate feathery stem plant with bright green needle-like foliage. Forms airy clouds in the background; CO2 and intense light keep it compact and lush.
Taxonomy
- Family: Haloragaceae
- Genus: Myriophyllum
- Scientific name: Myriophyllum sp. 'Guyana'

Habitat
Myriophyllum is a near-cosmopolitan genus of submersed stem plants (Haloragaceae) of ponds, lakes and slow streams, with finely pinnate whorled leaves. Several species are invasive outside their native range. In the Aquairi knowledge base, populations associated with this form are recorded from South America.

- Lighting: high
- CO2: recommended
- Temperature: 22-28 °C (72-82 °F)
- pH: 5.5-7
- GH: 2-8 °dGH
- Substrate: aquasoil
- Maximum height: 40 cm
- Growth rate: fast
- Recommended placement: background
Placement
A feathery midground-to-background stem grown in dense groups; bright light keeps the whorls tight, while shade leaves it sparse and elongated. In the Aquairi knowledge base this form is recommended for the background under high light with pressurised CO2 injection, using undefined.
Propagation
Propagated by cuttings; trimmed tops replant readily and the stem branches freely from below the cut. Documented propagation techniques for this entry include: stem cuttings.
Common issues
The fine foliage traps detritus and is prone to algae when flow or maintenance is poor; insufficient light produces thin, widely spaced whorls.
