Plant-Damaging Tetras to Avoid

While most tetras are plant-safe, certain species can damage aquatic vegetation and should be avoided in planted setups:

Buenos Aires Tetras

These large, boisterous tetras are notorious plant eaters that will systematically destroy soft-leaved plants. Expert planted tank forums consistently warn against including them in planted aquariums.

Silver Tip Tetras

While generally peaceful, silver tip tetras occasionally nibble on delicate plant leaves, particularly new growth on stem plants.

Blind Cave Tetras

Their aggressive feeding behavior and lack of visual cues can lead to accidental plant damage and substrate disruption.

Optimizing Tetra Health in Planted Aquariums

Water Parameter Management

Planted aquariums often maintain specific water conditions that benefit both plants and tetras:

• pH Range: 6.0-7.0 (slightly acidic for most plants)
• Temperature: 72-78°F (optimal for both plants and tetras)
• Hardness: Soft to moderate (promotes plant nutrient uptake)
• CO2 Levels: 20-30 ppm (benefits plants without harming fish)

Feeding Strategies

Proper feeding in planted tanks requires careful balance to avoid excess nutrients that promote algae growth:

• Small frequent meals: Reduces waste accumulation
• High-quality foods: Minimizes nutrient pollution
