Algae (green spot / black beard)
Signs: Green circular spots or dark bristly patches coat leaves, especially in high-light, low-CO2 tanks
Control: Reduce light intensity and duration; supplement with liquid carbon; stock Nerite snails and Amano shrimp for biological control
Pest snails
Signs: Small irregular holes or translucent areas in new growth where snails have rasped the tissue
Control: Manual removal at night; assassin snails as biological control; maintain good tank hygiene to limit snail reproduction
Spider mites (emersed only)
Signs: Stippled yellowing and fine webbing on leaves when kept in warm, dry emersed setups
Control: Increase humidity with a lid or dome; spray with diluted neem oil or insecticidal soap; ensure good air circulation to prevent fungal issues
