Blyxa Aubertii
Blyxa aubertii
Plantae›Tracheophyta›Liliopsida›Alismatales›Hydrocharitaceae
Blyxa aubertii is a delicate, fine-leaved stem plant native to Southeast Asia, featuring narrow, bright green leaves arranged in whorls along slender stems. It grows moderately fast under good conditions and is popular for creating a feathery, natural appearance in the midground to background. The plant requires consistent care but rewards attentive aquarists with lush, vibrant growth.

Common diseases 4Melt / Transition Shock, Iron Deficiency / Chlorosis, Algae Overgrowth on Leaves, Nutrient Deficiency (Macronutrients)
Melt / Transition Shock
Leaves become translucent, mushy, or dissolve rapidly after planting; stems weaken and collapse
Ensure stable water parameters (pH, temperature, hardness); provide high light and CO2 supplementation; perform gradual acclimation if transitioning from emersed to submersed form; maintain nutrient-rich substrate and water column fertilizers
Iron Deficiency / Chlorosis
New leaves turn pale yellow or white while veins remain green; older leaves stay darker green
Dose liquid iron fertilizer (chelated iron) 1-2x weekly; ensure adequate lighting to promote nutrient uptake; check that substrate contains micronutrients or add fertilizer tabs
Algae Overgrowth on Leaves
Green, brown, or black algae coating fine foliage; leaves appear dull and growth slows
Increase water circulation and reduce photoperiod to 8-10 hours daily; add algae-eating shrimp or fish (Amano Shrimp, Otocinclus); manually remove affected leaves; maintain nutrient balance to reduce excess nutrients favoring algae
Nutrient Deficiency (Macronutrients)
Stunted growth, yellowing or browning of older leaves, weak stems, pale new growth
Dose comprehensive liquid fertilizer containing NPK (nitrogen, phosphorus, potassium) 2-3x weekly; ensure fish bioload provides adequate nitrogen; perform 30-50% water changes weekly to replenish trace minerals
