What's eating my anubias hastifolia?

Anubias hastifolia is a tall, spear-leaved aquarium and paludarium species. Like all Anubias, its slow leaf turnover makes green spot algae the primary enemy. Large herbivorous fish and snails pose secondary risks. In paludarium conditions, spider mites can occasionally attack emersed leaves in dry air.

Hard green spots on older leaves, especially in high-light tanks with low CO2; leaves become permanently marked. Provide moderate rather than high light; maintain phosphate balance; use nerite snails and otocinclus as biological control.

Holes and grazing marks on leaf surfaces; large leaves are targeted by larger snails. Manage snail populations with assassin snails; manual removal; avoid overfeeding which drives snail population booms.

Fine stippling on emersed leaves; fine webbing between leaves and stems; leaves yellow and drop in severe cases. Mist emersed leaves regularly to maintain humidity; isolate affected plants; wipe leaves with a damp cloth; apply neem oil spray if infestation is established.
