Why Pennywort is Every Aquarist’s Secret Weapon

Step-by-Step: Create Your Pennywort Paradise

Materials Needed

• 10-gallon tank (minimum)
• LED full-spectrum light ($25-50)
• Clay substrate (Fluval Stratum recommended)
• Pennywort bunch (3-5 stems)
• Nano fish (ember tetras, chili rasboras)

Pro Setup Guide

1. Substrate Strategy
   Layer 1″ organic potting soil under 1.5″ sand. Pennywort’s roots mine nutrients from this “dirted” base.
2. Planting Hacks

• Floating Method: Simply drop stems in water
• Attached Growth: Superglue to lava rocks
• Carpet Technique: Use plant weights every 2″

3. Fish Pairing Secrets
   | Fish Type | Pennywort Benefit |
   |—————-|—————————-|
   | Betta Fish | Leaf hammocks for resting |
   | Shrimp Colonies| Biofilm feeding platform |
   | Schooling Fish | Dappled light reduces stress|
