Melting or blackening of leaves, mushy stems, foul odor from substrate

Improve water circulation, reduce organic buildup, perform partial water changes, remove affected leaves, ensure adequate substrate nutrients

Yellowing leaves, stunted growth, pale new growth, leaf holes

Add comprehensive liquid fertilizer or root tabs, ensure adequate lighting, test water parameters for macronutrients (nitrogen, phosphorus, potassium)

Green or brown algae coating leaves, reduced light penetration

Reduce lighting duration to 6-8 hours daily, increase water changes, add algae-eating fish or shrimp, manually remove algae buildup

Brown or black spots on leaves with yellow halos, progressive leaf damage

Remove affected leaves promptly, improve water quality with frequent changes, reduce tank bioload, avoid overcrowding
