This is a full technical guide focused on the Tici (Tissue Culture / In Vitro) form used in aquascaping.

1️⃣ Botanical & Morphological Profile

• Family: Cyperaceae

• Origin: Widely distributed (Europe, North America, Asia)

• Growth Type: Rhizomatous grass-like sedge

• Blade Shape: Very thin, hair-like cylindrical stems

• Height (submerged): 5–15 cm (can be trimmed shorter)

• Color: Bright green

It spreads through underground runners, forming a soft meadow effect.

2️⃣ Tici (In Vitro) Form

Lab-grown in sterile nutrient gel.

Advantages

• Pest-free (no snails, algae spores)

• No pesticides (shrimp-safe)

• Clean and compact portions

• Ideal for starting new tanks

Planting Instructions

1. Remove from cup.

2. Rinse off gel completely.

3. Divide into small clumps (5–8 blades).

4. Plant 1–2 cm apart with tweezers.

Small, evenly spaced plugs establish faster and spread more uniformly.

3️⃣ Aquarium Requirements

Compared to E. parvula, this species generally grows taller and softer.

4️⃣ Growth Behavior

With CO₂ + High Light

• Dense grassy field

• Faster runner production

• Compact 5–8 cm height

Without CO₂

• Slower spreading

• Taller (10–15 cm)

• Less dense carpet

5️⃣ Nutrient Demand

Moderate feeder (mainly through roots).

Needs:

• Nitrogen (NO₃)

• Potassium (K)

• Iron (Fe)

• Root nutrients (aquasoil or root tabs)

Deficiency symptoms:

• Yellowing tips → Nitrogen or iron deficiency

• Slow spreading → Low nutrients or compacted substrate

6️⃣ Maintenance

• Trim to desired height (2–5 cm for tight carpet).

• Remove trapped debris.

• Maintain good water circulation.

• Replant uprooted runners if necessary.

Frequent trimming encourages horizontal spread and thickening.

7️⃣ Common Problems

❌ Melting After Planting

Normal transition from emersed to submerged form (1–3 weeks).

❌ Sparse Growth

Cause: Weak lighting or low nutrients
Fix: Increase light and stabilize fertilization

❌ Algae Between Blades

Cause: Poor flow or unstable CO₂
Fix: Improve circulation and injection stability

8️⃣ Aquascaping Use

• Nature aquariums

• Iwagumi layouts

• Shrimp tanks

• Background grass in nano tanks

• Midground meadow effect in larger tanks

Popularized in layouts inspired by Takashi Amano.

9️⃣ Comparison: Acicularis vs Parvula

Acicularis = taller natural meadow
Parvula = shorter compact lawn

🔟 Summary

Tici Eleocharis acicularis is:

• A fine-leaved grassy carpeting plant

• Moderately demanding

• Responsive to CO₂ and light

• Ideal for natural-style aquascapes
