Frequently asked questions
Are the white veins on Rosanervig a deficiency?
No — the light veination is the stable trait this cultivar was selected for, and it actually intensifies when the plant is thriving. Deficiency on AR looks different: curled tips, melting lower leaves, or overall pale washed-out color rather than crisp bright veins.
Where should I place Rosanervig in the aquascape?
Midground, with clear line of sight and nothing overshadowing it. It grows too slowly to compete with background stems, and its pink-and-white pattern is the kind of focal accent that works best as a deliberate cluster of three to five stems rather than scattered singles.
