Narrow-leaf vallisneria
Measured underwater with an Apogee MQ-510at this plant’s position. Working ranges are practical reference figures, not biological thresholds. The full survey sets out how the number was taken and what it does not establish.
Rosette; propagates by runners, throwing daughter plants along the substrate.
Back wall, where its height is an asset and its spread can be managed against the glass.
Deep green. Color is not the reason it is here; structure and movement are.
General to the species. What this plant has actually done in this aquarium is recorded under observations.
Trim runners to stop it colonizing neighboring streets. Leaf tips can be shortened, though cut ends stay visible.
Nothing recorded specific to this plant in this aquarium yet. The scape is still growing in; observations are added when there is something specific to report rather than to fill the section.
Photograph pending. Planned: a current photograph at matched camera settings, repeated at intervals so color can be compared across time rather than described.
