What's eating my echinodorus bleheri?
Pond/bladder snails
Signs: Circular or ragged holes punched through large leaf blades; rapid population explosions in warm tanks
Control: Hand-remove adults; add assassin snails or a clown loach; avoid overfeeding the tank
Green spot algae / BBA
Signs: Hard green discs or dark tufts on older leaves; accelerates leaf senescence
Control: Remove heavily colonised old leaves; add nerite snails for green spot; improve CO2 and flow to deter BBA
Aquatic moth larvae (Nymphula / Synclita spp., outdoor ponds)
Signs: Leaf pieces cut and rolled into shelters; leaves riddled with cuts
Control: Remove larvae by hand; introduce surface-feeding fish; net the pond surface to exclude egg-laying moths in summer
