Pendahuluan
Kamu cuma beli 1 pot tanaman, tiba-tiba 2 minggu kemudian ada 50+ siput kecil di kaca tank—welcome to pest snail invasion! Pond snails, ramshorn, dan Malaysian Trumpet Snail (MTS) adalah hitchhiker paling umum yang datang gratis dengan tanaman aquascape baru.
Snail pest tidak berbahaya untuk ikan atau udang, tapi mereka berkembang biak sangat cepat (1 snail → 100+ dalam 2 bulan), merusak estetika tank, dan beberapa jenis makan tanaman sehat. Artikel ini akan membahas identifikasi 3 jenis snail pest, prevention dengan quarantine, dan treatment efektif dengan assassin snail atau manual removal.
Prevention 10x lebih mudah daripada eradikasi—always quarantine plants! Tapi jika sudah terlambat dan tank kamu penuh pest snails, ada solusi efektif yang akan kita bahas lengkap.
3 Jenis Snail Pest Aquascape
1. Pond Snail (Physa acuta/fontinalis)
Penampilan:
- Shell kecil (5-10mm), pointed cone shape
- Warna coklat atau abu-abu
- Shell spiral ke kiri (sinistral)
- Body transparan keabu-abuan
Reproduksi:
- Sangat cepat (hermaphrodite—bisa self-fertilize)
- Lay eggs setiap 2 minggu (20-50 eggs per clutch)
- Eggs transparan jelly-like di daun atau kaca
- 1 snail → 100+ dalam 2 bulan jika overfed tank
Behavior:
- Aktif siang dan malam
- Eat algae BUT juga makan healthy plant leaves
- Target: Soft plants (Monte Carlo, HC Cuba, Rotala)
- Bisa damage carpet plants dalam jumlah besar
Verdict:
- ❌ Pure pest (tidak ada benefit)
- ❌ Damage tanaman
- ❌ Reproduce uncontrollably
- ❌ Unsightly (jelek di kaca)
2. Ramshorn Snail (Planorbidae family)
Penampilan:
- Shell flat spiral (seperti tanduk domba)
- Warna: Brown (common), red, blue (rare)
- Size: 5-15mm diameter
- Body warna match shell
Reproduksi:
- Fast (hermaphrodite, eggs on glass/leaves)
- Eggs pink/red jelly clusters
- Population explosion: 50+ dalam 1-2 bulan jika overfed
Behavior:
- Primarily algae eaters
- Less plant damage dibanding pond snails
- Aktif siang dan malam
- Poop a lot (bioload tinggi)
Verdict:
- ⚠️ Controversial (some aquascapers keep small numbers)
- ✅ Small ones (<5mm) help clean algae
- ✅ Red/blue varieties attractive
- ❌ Common brown ones usually pest
- ❌ Overpopulation problem
Note: Red atau Blue Ramshorn dalam jumlah kecil (5-10) bisa beneficial dan estetik, tapi common brown ramshorn biasanya dianggap pest.
3. Malaysian Trumpet Snail (MTS - Melanoides tuberculata)
Penampilan:
- Cone-shaped shell dengan brown/grey pattern
- Size: 10-20mm (lebih besar dari pond/ramshorn)
- Pointed tip, ridged shell
- Shell keras dan tajam
Reproduksi:
- Livebearing (give birth to live baby snails)
- 10-20 babies per bulan
- Population explosion: Moderate-slow
- Kamu tidak akan lihat mereka sampai ratusan sudah di substrate
Behavior:
- Burrow in substrate (live underground)
- Nocturnal (hide during day, active at night)
- Aerate substrate (prevent compaction)
- Eat leftover food in substrate
Verdict:
- ⚠️ Highly controversial
- ✅ Aerate substrate (prevent anaerobic pockets = hydrogen sulfide gas)
- ✅ Eat leftover food (cleanup crew)
- ❌ Hard to remove (live in substrate)
- ❌ Overpopulation indicator (means overfeeding)
- ❌ Sharp shells (can cut hands during maintenance)
Note: Beberapa aquascaper keep MTS intentionally untuk substrate aeration (especially thick substrate >5cm), others consider pure pest.

Prevention (Best Strategy!)
Quarantine All New Plants (2-3 Weeks)
Step-by-Step:
- Rinse thoroughly under tap water (remove visible snails/eggs)
- Inspect carefully for snail eggs (clear jelly blobs on underside of leaves)
- Soak in separate container 2-3 weeks
- Check daily for snails (remove any that appear)
- Change water every 3 days (kill hatching snails)
Why 2-3 weeks? Snail eggs hatch dalam 7-14 hari. Quarantine 3 minggu memastikan semua eggs sudah hatch dan snails removed.
Plant Dip Methods (Kill Eggs Before Planting)
Method 1: Bleach Dip (Nuclear Option)
- Ratio: 1:20 bleach:water (1 bagian bleach, 20 bagian air)
- Duration: 30 seconds (maksimal 1 menit untuk hardy plants)
- Process:
- Soak plant dalam bleach solution 30 detik
- Rinse thoroughly under running water 3x
- Soak dalam air dengan dechlorinator 5 menit
- Rinse lagi, siap tanam
- Effectiveness: 99% (kills eggs, snails, algae, pesticides)
- Risk: Stressful untuk delicate plants (moss, Riccardia)
Method 2: Alum Dip (Safer)
- Ratio: 1 tablespoon alum per gallon water
- Duration: 24 hours
- Process: Soak plant, rinse thoroughly, siap tanam
- Effectiveness: 95% (kills eggs/snails)
- Risk: Safe untuk most plants
Method 3: Salt Dip
- Ratio: 1 cup aquarium salt per gallon
- Duration: 15-20 minutes
- Process: Soak, rinse, tanam
- Effectiveness: 90% (kills snails, less effective untuk eggs)
- Risk: Good untuk hardy plants only
Tissue Culture Plants (100% Pest-Free)
- What: In-vitro plants grown in sterile lab conditions
- Price: Rp 50-100k per cup (lebih mahal dari potted plants)
- Pros: 100% pest-free, disease-free, algae-free, pesticide-free
- Cons: Expensive, limited species available
- Recommended for: Shrimp tanks (no pesticide risk), high-end aquascapes
“Prevention 10x lebih mudah daripada eradikasi—always quarantine!”
Manual Removal Methods
Hand Picking
Best for: Small populations (5-20 snails)
Process:
- Remove visible snails daily dari glass, hardscape, leaves
- Best time: Night dengan flashlight (snails most active)
- Crush atau buang ke sampah (jangan flush—bisa invasive species)
Effectiveness: 30-50% population reduction per week
Pros: Free, no chemicals, immediate Cons: Time-consuming, tidak eliminate eggs
Snail Traps
DIY Trap:
- Lettuce atau cucumber slice dalam tank overnight
- Snails akan gather di daun
- Remove daun dengan snails pagi hari
- Repeat daily 1-2 weeks
Commercial Trap:
- Snail trap dengan bait chamber (Rp 30-50k)
- One-way entrance (snails masuk, tidak bisa keluar)
- Bait dengan algae wafer atau blanched vegetable
Effectiveness: 70-80% population reduction dalam 2 minggu
Pros: Passive (set and forget overnight) Cons: Tidak eliminate eggs, perlu repeat
Substrate Vacuuming (For MTS)
Process:
- Deep vacuum substrate during water change
- Suck up buried MTS dari substrate
- Repeat weekly
Effectiveness: Slow (months to eliminate)
Pros: Also removes detritus (improve water quality) Cons: Very slow, disturbs substrate, tidak dapat semua MTS
Chemical/Biological Control
Assassin Snail (Clea helena) - Best Biological Control
What: Carnivorous snail yang makan pest snails
Penampilan:
- Size: 15-20mm
- Striped shell (yellow/brown bands)
- Cone-shaped
Effectiveness:
- Ratio: 1 assassin per 5-10 pest snails
- For 30L tank with infestation: 3-5 assassins
- Timeline: 1-2 bulan untuk eliminate population
- Success rate: 95%+
Price: Rp 15-30k per snail (Tokopedia/Shopee)
Pros:
- ✅ Natural, no chemicals
- ✅ Permanent solution (assassins stay in tank as patrol)
- ✅ Safe untuk ikan, udang, tanaman
- ✅ Attractive (striped shell)
Cons:
- ❌ Also breed (slower than pests, manageable)
- ❌ Eat shrimp babies jika hungry (feed them occasionally)
- ❌ Expensive upfront (Rp 100-150k untuk 5 assassins)
Behavior:
- Burrow in substrate (hunt MTS underground)
- Grab pest snails dengan proboscis (suck out body)
- Eat 1-2 snails per day per assassin
Maintenance:
- Feed occasionally dengan sinking pellets (prevent shrimp baby predation)
- Keep 2-3 assassins permanently sebagai patrol force
Recommended method untuk planted shrimp tanks (safe for all)
Snail-Eating Fish
Clown Loach / Yoyo Loach:
- Excellent snail eaters (crush shells)
- Cons: Too large untuk nano tanks (grow 15-30cm), dig substrate (disturb plants)
Dwarf Chain Loach:
- Smaller (5-7cm), better untuk smaller tanks
- Cons: Less effective, still dig substrate
Pufferfish (Dwarf Pea Puffer):
- Excellent snail eaters (favorite food)
- Cons: Aggressive, fin nippers, eat shrimp, not for community tanks
Verdict: ❌ Not recommended untuk aquascapes (loaches dig substrate, disturb plants; puffers aggressive)
Chemical Treatments (LAST RESORT, Risky)
Copper-Based Medications:
- Products: Fritz Copper Safe, Cupramine
- Kills: ALL invertebrates (snails, shrimp, crabs)
- Dosage: Follow product instructions carefully
- Process:
- Remove all shrimp/beneficial snails
- Treat tank 7-14 days
- Massive water changes to remove copper
- Test copper levels (must be 0 before re-adding inverts)
WARNING:
- ❌ Copper lethal to shrimp permanently (absorbs into substrate)
- ❌ NEVER use in shrimp tanks
- ❌ Only for fish-only tanks
“Only use if no shrimp, no inverts, fish-only tank—otherwise choose assassin snails”
Preventing Re-infestation
Reduce Feeding
Why: Pest snails explode due to excess food
Action:
- Feed fish sparingly (1-2 minutes to finish)
- Remove uneaten food after 5 minutes
- Feed less frequently (1x per day sufficient)
Result: Snail population crashes tanpa food source
Regular Cleaning
Remove:
- Dead leaves (snail food)
- Uneaten food
- Detritus (vacuum substrate weekly)
Result: Less food = less snails
Quarantine Forever
Rule: ALWAYS quarantine new plants
Don’t: Skip quarantine setelah one success (complacency kills)
Remember: One untreated plant = re-infestation
Maintain Assassins
Strategy: Keep 2-3 assassin snails permanently in tank
Benefit: Patrol force (eat any new hitchhikers immediately)
Cost: Rp 50-100k one-time (assassins live 2-3 years)
FAQ
Apakah pest snails berbahaya untuk ikan/udang?
Tidak berbahaya. Pest snails tidak attack atau eat ikan/udang. Mereka hanya jelek secara estetika dan bisa damage tanaman jika populasi sangat besar. Tapi mereka tidak toxic atau aggressive.
Berapa assassin snail dibutuhkan untuk tank 60L?
3-5 assassin snails untuk tank 60L dengan moderate infestation (50-100 pest snails). Ratio: 1 assassin per 5-10 pest snails. Untuk heavy infestation (200+ pests), gunakan 5-7 assassins. Timeline: 1-2 bulan untuk eliminate population.
Bisa pakai salt untuk bunuh snails tanpa bunuh tanaman?
Tidak. Salt concentration yang cukup untuk kill snails (1 tablespoon per 5-10L) juga akan damage atau kill kebanyakan tanaman. Salt treatment hanya untuk items di luar tank (hardscape, tools), bukan in-tank treatment untuk planted aquascapes.
Kenapa pest snails muncul tiba-tiba banyak?
Overfeeding. Pest snails berkembang biak cepat jika ada excess food. Jika populasi meledak, evaluate feeding schedule—feed less, remove uneaten food, vacuum substrate lebih sering. Snail population akan turun natural jika food source berkurang.
Apakah MTS (trumpet snail) perlu dibasmi atau dibiarkan?
Depends on preference. MTS aerate substrate (beneficial untuk thick substrate >5cm), tapi overpopulation jelek. Jika populasi kecil (10-20), bisa dibiarkan. Jika ratusan, reduce feeding dan consider assassin snails. Beberapa aquascaper keep MTS intentionally, others eliminate completely.
Berapa lama assassin snail bunuh semua pest snails?
1-2 bulan untuk eliminate 90%+ population. Assassin snails eat 1-2 pest snails per day. Untuk tank dengan 50 pest snails dan 5 assassins: 50 snails ÷ (5 assassins × 1.5 snails/day) = ~7 hari untuk adults, tapi eggs masih hatch jadi butuh 4-8 minggu total.
Kesimpulan
Snail pest control aquascape dimulai dari prevention dengan quarantine tanaman (2-3 minggu atau bleach dip). Jika sudah terlambat dan tank penuh pest snails, assassin snails adalah solusi terbaik untuk planted/shrimp tanks—natural, efektif (95%+ elimination dalam 1-2 bulan), dan permanent.
Manual removal dan traps bisa reduce population 50-70%, tapi tidak eliminate eggs. Chemical treatments (copper) NEVER untuk shrimp tanks (lethal permanently). Snail-eating fish (loaches, puffers) not recommended untuk aquascapes (dig substrate, aggressive).
Setelah eliminate pest snails, maintain 2-3 assassins sebagai patrol force dan ALWAYS quarantine new plants. Prevention 10x lebih mudah daripada eradikasi!
