Hygrophila lancea 'Araguaia' problems — and how to fix them
Hygrophila lancea 'Araguaia' (Hygrophila lancea 'Araguaia') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Loss of red colour / reverting to green
Insufficient light or low CO2 makes new growth plain green and stretched. Raise PAR, confirm CO2 reaches 20-30 ppm, and keep iron dosing steady.
Stunted or twisted tips
Usually a micronutrient deficiency or fluctuating CO2. Stabilise CO2 across the photoperiod and ensure adequate magnesium, calcium and trace elements.
Lower-leaf melt after planting
Emersed-grown nursery stems often shed leaves when transitioning to submerged form. Keep parameters stable and trim, and new submerged growth will follow.
Algae on slow new growth
Its slower pace lets spot and hair algae colonise leaves in unstable tanks. Improve flow, balance light to CO2, and keep nutrients consistent.
