Common diseases 4Crypt Melt, Iron Deficiency, Algae on Leaves, Rhizome Rot

Crypt Melt

Symptoms

Leaves turn translucent, mushy, and dissolve; plant appears to rot from the base

Treatment

Reduce water changes temporarily, maintain stable water parameters, ensure good water circulation; plant typically recovers and regrows within weeks

Iron Deficiency

Symptoms

Yellowing of new leaves while veins remain green; stunted growth

Treatment

Dose with liquid iron fertilizer or all-in-one fertilizer; ensure adequate lighting to support nutrient uptake

Algae on Leaves

Symptoms

Green or brown algae coating leaf surfaces, reducing photosynthesis

Treatment

Manually remove algae with soft brush; reduce lighting duration; increase water circulation; add algae-eating shrimp or fish

Rhizome Rot

Symptoms

Base of plant becomes soft and blackened; leaves detach easily

Treatment

Remove affected portions with clean scissors; improve water circulation and reduce organic waste; avoid burying rhizome too deeply in substrate
