Feng Shui Aquarium Fish: Types, Numbers, and Placement Rules
A friend in Singapore spent $15,000 on an Asian Arowana — a single fish. His wife thought he'd lost his mind. His feng shui consultant congratulated him on a wise investment. Three months later, his import business landed its biggest contract ever.
Coincidence? Almost certainly. But try telling that to the thriving community of feng shui fish enthusiasts across Asia who track their aquarium inhabitants with the same attention a stock trader gives their portfolio.
Fish in feng shui aren't pets. They're energy tools (风水法器 Fēng Shuǐ Fǎ Qì). The aquarium creates moving water (wealth energy), and the fish keep that water alive and active. But the specific fish you choose — their species, color, number, and behavior — determine what kind of wealth energy you're activating.
Why Fish and Water Equal Wealth
The connection is rooted in the Chinese language itself:
- 水为财 (Shuǐ Wéi Cái): "Water is wealth" — the foundational feng shui principle
- 鱼 (Yú) sounds like 余 (Yú): "surplus" or "abundance"
- 年年有余 (Nián Nián Yǒu Yú): "Surplus year after year" — one of the most common Chinese New Year blessings, always depicted with fish
- 金鱼 (Jīn Yú) sounds like 金余 (Jīn Yú): "gold surplus"
Fish swimming in water = abundance flowing through wealth. The symbolism is layered and reinforcing.
Fish Species and Their Feng Shui Properties
| Fish Type | Chinese Name | Element | Feng Shui Property | Price Range | |---|---|---|---|---| | Asian Arowana | 龙鱼 (Lóng Yú) | Water/Wood | Supreme wealth, dragon energy | $300-$300,000 | | Goldfish | 金鱼 (Jīn Yú) | Metal/Water | General prosperity, gold surplus | $1-$50 | | Koi | 锦鲤 (Jǐn Lǐ) | Water/Fire | Perseverance, transformation | $10-$10,000 | | Flowerhorn | 罗汉鱼 (Luó Hàn Yú) | Water/Earth | Luck, fortune (the "kok" bump) | $50-$5,000 | | Blood Parrot | 血鹦鹉 (Xuè Yīng Wǔ) | Water/Fire | Prosperity, vitality | $10-$100 | | Silver Arowana | 银龙鱼 (Yín Lóng Yú) | Metal/Water | Wealth protection, metal energy | $30-$500 | | Black Moor Goldfish | 黑牡丹 (Hēi Mǔ Dan) | Water | Absorbs negative energy | $5-$30 | | Plecostomus | 清道夫 (Qīng Dào Fū) | Water/Earth | Cleans negative energy | $5-$20 |
The Arowana: King of Feng Shui Fish
The Asian Arowana (龙鱼 Lóng Yú — literally "dragon fish") holds a special place in feng shui. Its elongated body, large metallic scales, and barbels (whisker-like appendages) resemble a Chinese dragon. In feng shui, the dragon is the ultimate symbol of power and prosperity.
Arowana varieties and their specific properties:
- Gold Arowana (金龙 Jīn Lóng): The most prized. Represents pure wealth energy. Malaysian and Indonesian varieties are most valued.
- Red Arowana (红龙 Hóng Lóng): Represents fame and recognition alongside wealth. The "Super Red" variety from Kalimantan is legendary.
- Silver Arowana (银龙 Yín Lóng): More affordable. Represents wealth protection rather than wealth generation. Good for maintaining existing prosperity.
- Green Arowana (青龙 Qīng Lóng): Represents growth and new opportunities. Good for businesses in expansion phase.
The Arowana's behavior is also read as an omen. A healthy, active Arowana that swims smoothly = business flowing well. An Arowana that hides, refuses food, or becomes lethargic = warning sign. An Arowana that jumps out of the tank (they're notorious jumpers) = it "sacrificed itself" to absorb a major negative event meant for the owner.
Yes, people genuinely believe this. And yes, it affects how they respond to business challenges — often with increased caution and attention, which arguably produces better outcomes regardless of the fish's intentions.
Goldfish: The People's Feng Shui Fish
Not everyone can afford an Arowana. Goldfish (金鱼 Jīn Yú) are the accessible alternative, and they're perfectly effective in feng shui terms. The key is choosing the right varieties:
- Ranchu (兰寿 Lán Shòu): Round, plump body represents accumulated wealth. The "king of goldfish" in Japanese and Chinese culture.
- Oranda (狮头 Shī Tóu): The prominent head growth (wen) resembles a lion's mane — authority and power.
- Ryukin (琉金 Liú Jīn): Deep body, flowing fins. Represents elegance and steady wealth.
- Black Moor (黑牡丹 Hēi Mǔ Dan): The essential "negative energy absorber." Every feng shui aquarium should have at least one.
The Number Rules
The number of fish in your aquarium follows specific feng shui calculations:
By Luo Shu number:
| Count | Element | Meaning | Suitability | |---|---|---|---| | 1 | Water | New beginning, career | ✅ Good for career focus | | 2 | Earth | Partnership, but also illness star | ⚠️ Avoid for business | | 3 | Wood | Growth, but also conflict star | ⚠️ Mixed | | 4 | Wood | Academic, romance | ⚠️ Not ideal for wealth | | 5 | Earth | Center, but misfortune star | ❌ Avoid | | 6 | Metal | Authority, heaven luck | ✅ Good | | 7 | Metal | Loss in current period | ❌ Avoid | | 8 | Earth | Wealth, prosperity | ✅✅ Best for wealth | | 9 | Fire | Future prosperity, completion | ✅✅ Excellent |
The most popular configurations:
8 fish (八条鱼 Bā Tiáo Yú): The wealth number. Usually 7 red/gold + 1 black. The black fish absorbs negative energy while the others generate prosperity.
9 fish (九条鱼 Jiǔ Tiáo Yú): The completion number. Usually 8 red/gold + 1 black. Nine represents the highest single digit — fullness and longevity of wealth.
6 fish (六条鱼 Liù Tiáo Yú): The smooth-flow number. Good for businesses that need steady, reliable income rather than dramatic windfalls.
1 Arowana: A single Arowana is a complete feng shui statement on its own. The dragon fish is so powerful that it doesn't need companions. In fact, Arowanas are territorial and often can't be kept with other large fish.
Color Combinations
The color of your fish determines the elemental energy they bring:
| Fish Color | Element | Energy | Role in Aquarium | |---|---|---|---| | Red 红 | Fire | Passion, fame, activation | Primary wealth activator | | Gold 金 | Metal/Earth | Wealth, prosperity | Primary wealth attractor | | White 白 | Metal | Clarity, purity | Supporting energy | | Black 黑 | Water | Absorption, protection | Negative energy absorber | | Blue 蓝 | Water | Career, flow | Career support | | Multi-colored | Mixed | Diverse energy | General balance |
The ideal color ratio for a wealth-focused aquarium: predominantly red/gold with one black fish. This creates a fire-earth productive cycle (fire produces earth = wealth) with a water-element protector.
Tank Placement
Where you place the aquarium determines which life area it activates:
| Placement | Sector | Effect | |---|---|---| | Near front entrance | Qi mouth | Activates incoming wealth energy | | Living room, left side (facing out) | Dragon side | Activates yang wealth | | North sector | Career | Supports career advancement | | Southeast sector | Wealth corner | Direct wealth activation | | Near cash register (business) | Transaction point | Activates money flow | | East sector | Family/health | Supports family prosperity |
Placements to avoid:
- Bedroom: Water in the bedroom creates emotional instability and can activate negative water stars
- Kitchen: Water-fire clash with the stove
- Bathroom: Already too much water energy; adding more creates excess
- Directly under a beam: The beam presses down on the water energy, suppressing wealth
- South sector: Fire direction — water here creates elemental conflict
- On the floor: The tank should be elevated (on a stand or cabinet) to keep the water energy at a functional level
Maintenance as Feng Shui Practice
A feng shui aquarium requires more maintenance attention than a regular pet fish tank because the energetic stakes are higher:
Water clarity: Murky water = murky finances. Keep the water crystal clear with proper filtration and regular water changes. The Chinese principle: 清水生财 (Qīng Shuǐ Shēng Cái) — "clear water generates wealth."
Fish health: Sick fish = sick wealth energy. Monitor fish health daily. Treat illness immediately. A tank full of diseased fish is worse than no tank at all.
Dead fish replacement: When a fish dies, replace it within 24-48 hours to maintain the correct number. The belief is that the dead fish absorbed a negative event meant for the owner — acknowledge this by replacing it promptly.
Some practitioners perform a small ritual when replacing a dead fish: thank the deceased fish for its protection, dispose of it respectfully (not in the trash — bury it or flush it with a moment of acknowledgment), and introduce the new fish with a brief intention-setting.
Tank cleanliness: Algae-covered glass, dirty gravel, and clogged filters represent neglected wealth. Clean the tank regularly — at minimum, partial water changes weekly and full cleaning monthly.
Pump and filter operation: The water must be moving. A tank with a broken pump is stagnant water — the opposite of wealth flow. If the pump breaks, fix it immediately or turn off the tank entirely until it's repaired. Stagnant water is worse than no water.
When Fish Die Repeatedly
If fish keep dying despite proper care, feng shui practitioners interpret this as a sign that the location has strong negative energy that the fish are absorbing. Possible responses:
- Check the Flying Star chart for the tank's sector — is there a 2-5 or 5-2 combination (illness + misfortune)?
- Check for external sha qi pointing at the tank's location
- Consider relocating the tank to a different sector
- Add metal remedies near the tank if earth-element negative stars are present
- Consult a feng shui practitioner for a full assessment
Repeated fish death is taken seriously in feng shui culture. It's not just bad fishkeeping — it's a diagnostic signal about the energy of the space.
The Minimalist Alternative
If maintaining a full aquarium feels overwhelming, there are simpler water-element alternatives:
- A small desktop fountain (moving water without the fish maintenance)
- A bowl of clean water changed daily (still water, but fresh)
- A water feature in the garden (outdoor wealth activation)
But none of these carry the same symbolic power as fish in water. The fish add the 余 (Yú, surplus) symbolism, the life energy, and the visual engagement that makes an aquarium the premier feng shui water feature.
Feng shui aquariums combine the wealth energy of water (水为财) with the surplus symbolism of fish (鱼=余). The species, number, color, and placement all follow specific rules — but the most important rule is maintenance. A clean, healthy aquarium generates wealth energy. A neglected one generates the opposite.
