What's eating my pogostemon helferi?
Algae (green spot, beard algae)
Signs: Hard green spots or dark tufts on the distinctive wavy leaves, stunting growth
Control: Maintain stable CO2, dose micro and macro fertilisers consistently, keep water flow reaching the low rosette
Snails (ramshorn, bladder snail)
Signs: Holes bitten into the textured leaf surface
Control: Assassin snails or manual removal; avoid copper-based treatments when shrimp share the tank
Herbivorous fish (larger plecos, goldfish)
Signs: Rosette uprooted or leaves grazed to stubs
Control: House with plant-safe species only; weight or glue base to hardscape to resist uprooting

Pogostemon helferi pests — FAQ
What is eating my pogostemon helferi?
Pogostemon helferi (Downoi) is a compact rosette aquarium plant vulnerable to algae smothering its crinkled leaves and to snail grazing. Its slow growth rate makes algae competition especially damaging. Shrimp may nip at algae on the leaves but generally do not harm the plant. Nutrient deficiency from algae competition is the top concern.
