How to grow monte carlo

Monte Carlo forms a bright green carpet of round leaves. It needs medium light, a nutrient substrate and ideally CO₂; fish that dig uproot it before it roots.

Common problems

  • Floating pieces: plant deeper or start the tank dry so roots grip first.
  • Carpet lifting off the substrate as it thickens; trim it back hard.

Light for monte carlo

Medium-light plants grow best under a planted-tank LED that spans the tank. Check the mounting length against your tank before buying: how to fit a planted light.
