Myriophyllum elatinoides

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

It is ideally placed in the midground or background of the aquarium, depending on the tank height. Due to its very fine and delicate texture, it shouldn't be hidden behind large, bulky plants. It looks stunning when planted in a small, dense group.

Botanical form

Stem

Myriophyllum elatinoides features incredibly fine, hair-like pinnate leaves arranged in whorls along a fragile stem. Its overall appearance is much more delicate and translucent than other Myriophyllum species. The ethereal, soft green texture makes it highly sought after.

Growth

Medium

This plant has a moderate to fast growth rate when conditions are optimal. Without sufficient light and CO2, its growth can stall, and the stems may become leggy and brittle. Regular trimming encourages a more compact and bushier appearance.

Substrate

Medium

Column fertilization

Recommended

It relies heavily on liquid fertilization absorbed directly through its extensive leaf surface area. Daily dosing of a comprehensive liquid fertilizer ensures the delicate foliage gets what it needs. Avoid drastic fluctuations in nutrient levels to prevent stunted growth.

Root fertilization

None

While it draws most nutrients from the water, a high-quality aquasoil provides a necessary safety net. Root tabs can be used carefully, though its primary root system is often fine and somewhat fragile. Good substrate helps keep the delicate stems anchored.

Trimming

Occasional

Trim with very sharp scissors to avoid crushing the fragile stems. The cut tops can be replanted to propagate, but be gentle as the stems can break easily. It is best to trim frequently rather than doing massive, stressful cuts at once.

Propagation

Cuttings

Propagation is done by stem cuttings, similar to other stem plants, but requires a gentler touch. Carefully snip a healthy top and plant it gently into fine substrate using tweezers. The bottom portion may sprout new side shoots if healthy.

Sensitivity

Moderate

This is one of the more sensitive Myriophyllum species, demanding clean water and stable parameters. It is highly susceptible to algae growth on its fine leaves if the tank balance is off. Good flow is essential, but it should not be so strong that it damages the delicate structure.

Layout role

Midground, accent, group

M. elatinoides provides an incredibly soft, cloud-like texture in an aquascape. It contrasts wonderfully against hardscape elements like dark wood or stones, softening harsh edges. It is often used as a delicate focal point or a subtle background filler.
