Rotala sold as 'Blood Red'
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.
Fine stem; upright, branches willingly.
Far-left background corner since 18 September 2026. It was originally planted rear-centre. This is the older of the two 'Blood Red' groups and is a separate plant from the Blood Red SG at #21.
In this tank it presents reddish brown rather than true crimson. Whether that is the clone or the conditions is not established.
General to the species. What this plant has actually done in this aquarium is recorded under observations.
Top and replant.
Photograph pending. Planned: a current photograph at matched camera settings, repeated at intervals so color can be compared across time rather than described.
