Syngonium podophyllum

Syngonium podophyllum, or Arrowhead Plant, is a popular foliage plant with striking arrow-shaped leaves. Though not a true aquatic plant, it can thrive in aquariums and ripariums when only the roots are submerged and the rest of the plant remains above the waterline. It’s a great addition to natural-style setups that combine terrestrial and aquatic elements.

Syngonium podophyllum – Care in Aquariums & Ripariums

✅ Best Use:

• Ripariums

• Open-top aquariums

• HOB filters (Hang-on-Back)

• Emersed setups (roots in water, leaves in air)

Can Syngonium Be Fully Submerged?

❌ No.

• Submerging the leaves and stems will cause rot and death.

• It is a terrestrial or semi-aquatic plant, suitable only when roots are in water.

How to Use in an Aquarium or Riparium

Growing Method

• Anchor the plant so only the roots are in water (e.g., in driftwood holes, HOB filters, floating pots).

• Ensure the crown and leaves stay above the waterline.

• Suitable for aquariums with open tops or partial land areas.

Water Conditions

• Temperature: 20–28°C (68–82°F)

• pH: 6.0–7.5

• Hardness: Soft to moderately hard water

• Flow: Moderate, avoid strong currents on roots

Light Requirements

• Bright, indirect light is ideal

• Can tolerate low light, but growth slows and leaves pale

• In ripariums, place near a window or use an LED grow light

Plant Care

⚠️ Common Problems

Is It Safe for Fish?

• ✅ Yes, as long as:

  • Only roots are in water

  • The plant is healthy and not rotting

• ❌ No, if the plant is decaying — it may release ammonia

✅ Summary

Great Companion Plants

• Pothos (Epipremnum aureum) – Excellent nitrate absorber

• Philodendron scandens – Similar care needs

• Peace Lily (Spathiphyllum) – For riparium/emersed zones

• Bucephalandra, Anubias – True aquatic companions

• Mosses (e.g., Java moss) – Good at waterline
