Pest identification
What's eating my limnophila aquatica?
Algae (green spot, staghorn)
Signs: Hard green spots or grey tufts encrust leaf surfaces, especially under high light
Control: Balance nutrients with fertiliser dosing, maintain CO2 at 20-30 ppm, add siamese algae eaters or otocinclus
Snails (ramshorn, pond snails)
Signs: Ragged holes in the delicate leaf whorls
Control: Manual removal, assassin snails, or a snail trap; avoid copper-based remedies if shrimp are present
Herbivorous fish (goldfish, large cichlids, plecos)
Signs: Leaves stripped or stems bitten through at substrate level
Control: Pair only with non-herbivorous species; anchor stems firmly in substrate to resist uprooting

Limnophila aquatica pests — FAQ
What is eating my limnophila aquatica?
Limnophila aquatica (Giant Ambulia) has large, delicate whorled leaves that are eagerly grazed by snails and herbivorous fish. Algae quickly colonises the broad leaf surface when lighting is unbalanced. It is one of the more demanding aquarium plants and nutrient deficiencies caused by competing algae are the most common problem keepers face.
