What's eating my alternanthera reineckii 'rosaefolia'?

Alternanthera reineckii 'Rosaefolia', a rosy-hued aquarium plant, faces the same threats as its relatives: snails are the primary pest, shredding soft leaves overnight, while algae can smother foliage in imbalanced tanks. Emersed specimens may attract aphids. Quarantine new additions and maintain stable water chemistry to protect vibrant leaf colour.

Irregular holes in leaves, stems eaten back; young shoots consumed first Hand-pick at night; introduce assassin snails or loaches; quarantine incoming plants

Filamentous green or black-beard algae clings to leaves, restricting light and causing die-back Correct CO2 and lighting duration; add fast-growing competitor plants; spot-treat BBA with hydrogen peroxide via syringe

Sticky deposits and distorted leaves on emersed portions; visible insect clusters on stems Rinse foliage with water; apply insecticidal soap or neem oil to emersed growth
