Troubleshooting
Echinodorus tenellus problems — and how to fix them
Echinodorus tenellus (Echinodorus tenellus) 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.
Leggy, tall growth (no carpet)
Insufficient light makes it stretch upward instead of spreading low. Increase lighting and add CO2 to achieve a tight carpet.
Slow to spread
Lean substrate or low light limits runner production. Provide root tabs, brighter light and CO2 to speed carpeting.
Iron-deficiency yellowing
Pale new leaves from low iron. Dose liquid iron and trace elements.
Melting after planting
Tissue-cultured or emersed-grown stock often melts as it converts to submerged form. Keep runners in place; new submerged leaves emerge within weeks.
Prevent echinodorus tenellus problems before they start
Most echinodorus tenellus issues are care-mismatch, not bad luck. Dial in the basics:
