🧬 Valid Scientific Species

The correct scientific name is:

Hydrocynus vittatus

The species was described by:

Castelnau in 1861

and belongs to the African tetra family:

Alestidae

The correct product title is:

African Tiger Fish – (Hydrocynus vittatus)

The species name:

vittatus

should always use a lowercase v when written as part of the scientific name.

---

🆚 African Tiger Fish vs. Goliath Tigerfish

The African Tiger Fish should not be confused with:

Goliath Tigerfish – Hydrocynus goliath

They are separate species.

African Tiger Fish – Hydrocynus vittatus

• Extremely large predator
• Maximum documented length approximately 41 inches
• Widespread across numerous African river systems
• Distinct horizontal dark stripes
• Massive predatory teeth

Goliath Tigerfish – Hydrocynus goliath

• Even larger species
• Primarily associated with the Congo Basin
• Heavier-bodied
• Capable of considerably greater maximum size

Although H. vittatus is smaller than the Goliath Tigerfish:

IT IS STILL A GIANT AQUARIUM FISH

and requires enormous permanent housing.

---

🐅 Appearance

The African Tiger Fish has a powerful:

TORPEDO-SHAPED BODY

built for high-speed pursuit.

Typical coloration includes:

• Bright silver
• Metallic gray
• Bronze-silver
• Golden highlights

with prominent:

DARK HORIZONTAL STRIPES

running along the body.

---

🔴 Fins

The fins can develop:

• Yellow
• Orange
• Red
• Reddish-orange

coloration.

The deeply forked caudal fin frequently develops:

DARK OR BLACK EDGING

which adds to the fish's dramatic appearance.

---

🦷 Famous Tigerfish Teeth

The African Tiger Fish is instantly recognizable by its:

LARGE, SHARP, CONICAL TEETH

The teeth remain clearly visible even when the mouth is closed.

They overlap between the:

• Upper jaw
• Lower jaw

creating the classic Tigerfish appearance.

---

⚠️ Serious Bite Hazard

These teeth are functional predatory weapons.

A large African Tiger Fish is capable of causing:

SERIOUS LACERATIONS

to a person.

Never:

• Hand-feed a large specimen
• Place hands near the mouth
• Attempt to grab the fish
• Corner it unnecessarily
• Handle it casually during aquarium maintenance

Use appropriate tools and barriers when working around large adults.

---

🏊 Built for Speed

The African Tiger Fish is not a slow-moving ambush predator.

It is an:

EXTREMELY FAST OPEN-WATER HUNTER

with a powerful tail designed for:

• Acceleration
• Pursuit
• Sudden strikes
• Long-distance swimming

This is one reason aquarium length is so important.

---

⚠️ Aquarium Size Is About More Than Body Length

A 36-inch Tiger Fish cannot be housed like a relatively sedentary 36-inch bottom-dwelling fish.

It needs enough room to:

• Accelerate
• Cruise
• Turn safely
• Avoid crashing into aquarium walls

Therefore:

SWIMMING SPACE IS CRITICAL

---

📏 Maximum Adult Size – Major Correction

Your older page states:

UP TO 30 INCHES

That size is possible, but it is not the species' documented maximum.

FishBase records:

105 CM / APPROXIMATELY 41.3 INCHES FORK LENGTH

for male/unsexed specimens.

A published maximum weight of:

28 KG / APPROXIMATELY 62 POUNDS

has also been recorded.

---

📏 Responsible Aquarium Planning

Not every captive African Tiger Fish will reach the scientific maximum.

However, permanent housing should not be designed around the hope that the fish remains unusually small.

For customer planning:

EXPECT A POTENTIAL 30–40+ INCH PREDATORY FISH

---

🚨 180 Gallons Is Not Permanent Adult Housing

The current page recommends:

180+ GALLONS

That should be removed as an adult recommendation.

A 180-gallon aquarium may temporarily house a:

SMALL JUVENILE

but it does not provide adequate permanent swimming space for a fish potentially exceeding three feet.

---

🏠 Permanent Adult Aquarium

For a mature specimen:

APPROXIMATELY 650+ GALLONS

should be considered a serious starting point.

For long-term housing of a very large adult:

1,000+ GALLONS IS PREFERRED

A professionally designed:

• Monster aquarium
• Custom indoor aquarium
• Large heated indoor pond

may ultimately be more practical than a conventional glass aquarium.

---

📐 Aquarium Dimensions

Gallons alone are not enough.

For an adult, prioritize approximately:

8–10+ FEET OF SWIMMING LENGTH

with:

3–4+ FEET OF FRONT-TO-BACK WIDTH

whenever possible.

Larger is better.

---

📏 Width Matters

An adult Tiger Fish must be able to:

TURN WITHOUT DIFFICULTY

A narrow aquarium can contain hundreds of gallons while still being unsuitable.

Prioritize:

LENGTH + WIDTH

rather than:

HEIGHT

---

🏊 Open Swimming Space

The center of the aquarium should contain substantial:

OPEN WATER

Avoid filling the aquarium with:

• Dense rock piles
• Large amounts of wood
• Excessive decoration
• Sharp structures

that reduce swimming room.

---

🪨 Aquarium Setup

A suitable setup may include:

• Large open swimming area
• Smooth rocks around the perimeter
• Limited large driftwood
• Sand or smooth gravel
• Very strong filtration
• Powerful circulation
• High dissolved oxygen
• Secure cover

Keep décor:

LOW + SMOOTH + SECURE

---

⚠️ Avoid Sharp Decorations

Tiger Fish can accelerate extremely quickly when frightened.

Sharp décor can cause:

• Facial injuries
• Eye injuries
• Scale damage
• Internal trauma

A relatively open aquarium is safer.

---

😨 Skittish Behavior

Despite being a powerful predator, African Tiger Fish can also be:

VERY SKITTISH

Sudden movement may trigger a high-speed escape response.

Possible triggers include:

• People approaching suddenly
• Dogs or cats near the aquarium
• Lights switching on abruptly
• Loud impacts
• Aggressive tankmates
• Sudden maintenance activity

---

💥 Collision Risk

A startled Tiger Fish may strike:

• Aquarium glass
• Covers
• Rocks
• Equipment

at considerable speed.

Repeated collisions can cause serious injury.

---

🌙 Lighting

Avoid sudden transitions from:

COMPLETE DARKNESS → BRIGHT LIGHT

Use:

• Gradual room lighting
• Dimmer lighting
• Timed lighting transitions where possible

to reduce startle responses.

---

🚨 Extremely Powerful Jumper

A Tiger Fish can:

LEAP FROM THE WATER

This is not a minor risk.

Wild Hydrocynus vittatus have even been scientifically observed:

LEAPING FROM THE WATER TO CAPTURE BIRDS

---

🔒 Secure Lid Is Mandatory

The aquarium must have a:

HEAVY, SECURE, ESCAPE-PROOF COVER

Cover openings around:

• Filters
• Plumbing
• Wires
• Overflow boxes

A large Tiger Fish can strike a lightweight lid with substantial force.

---

🌎 Native Distribution

Hydrocynus vittatus has an extremely broad distribution across:

SUB-SAHARAN AFRICA

It occurs in numerous large river and lake systems.

---

🌊 Major River Systems

Documented populations include portions of the:

• Congo Basin
• Zambezi Basin
• Okavango Basin
• Niger Basin
• Benue Basin
• Senegal Basin
• Chad Basin
• Limpopo system
• Nile system
• Omo system
• Rovuma system
• Shire system

---

🏞️ Major Lakes

The species is also found in major lakes and reservoirs including:

• Lake Tanganyika
• Lake Rukwa
• Lake Kariba
• Lake Mweru
• Lake Bangweulu

among other freshwater systems.

This is one of the more geographically widespread African predatory fishes.

---

🌊 Natural Habitat

African Tiger Fish primarily inhabit:

• Large rivers
• Major tributaries
• Lakes
• Reservoirs
• Open-water environments

They prefer:

WARM, WELL-OXYGENATED WATER

---

💨 High Oxygen Requirement

A large active predator consumes substantial oxygen.

Maintain:

VERY HIGH DISSOLVED OXYGEN

using:

• Strong surface agitation
• Large air stones
• Powerheads
• High-volume filter returns
• Sump filtration
• Circulation pumps

---

🌡️ Warm Water + Oxygen

A practical long-term temperature range is:

75–82°F / 24–28°C

As water becomes warmer:

ITS OXYGEN-HOLDING CAPACITY DECREASES

Therefore, strong aeration becomes even more important near the upper end of the temperature range.

---

💧 Water Parameters

A practical aquarium range is:

• 🌡️ Temperature: Approximately 75–82°F
• 💧 pH: Approximately 6.5–7.5
• 💨 Oxygenation: Very High
• 🌊 Water Movement: Moderate to Strong
• ☠️ Ammonia: 0 ppm
• ☠️ Nitrite: 0 ppm
• 🔄 Nitrate: Keep as low as reasonably practical

---

🌊 Water Movement

Provide:

MODERATE TO STRONG CIRCULATION

with sufficient open space for the fish to swim naturally.

Strong current should not create a situation where the fish is forced to constantly fight a jet of water.

The goal is:

CIRCULATION + OXYGEN + CLEAN WATER

---

💩 Massive Filtration Requirements

A large predatory fish eating high-protein foods produces:

A LARGE BIOLOAD

Permanent housing requires powerful:

• Mechanical filtration
• Biological filtration
• Water circulation

---

💧 Sump Filtration

For very large systems:

LARGE SUMP FILTRATION

is often one of the most practical options.

Benefits include:

• High biological capacity
• Large mechanical filtration area
• Increased total water volume
• Strong oxygen exchange
• Easier equipment management

---

🔄 Water Changes

Large regular water changes are important.

The exact schedule depends on:

• Aquarium volume
• Fish size
• Feeding
• Filtration
• Stocking
• Nitrate production

Monitor water quality rather than relying solely on a fixed calendar.

---

🍽️ Diet – Piscivorous Carnivore

The African Tiger Fish is:

A HIGHLY PREDATORY CARNIVORE

and becomes increasingly:

PISCIVOROUS

as it grows.

Scientific diet information indicates that fish larger than roughly:

90–100 MM

may become predominantly or essentially fish-eating predators.

---

🐟 Natural Diet

Wild prey includes various:

• Small fish
• Characins
• Barbs
• Sardine-like fishes

depending on the river system.

The species may also consume:

• Shrimp
• Other crustaceans
• Aquatic insects

---

🍽️ Captive Feeding

Suitable foods can include appropriately sized:

• Whole frozen fish
• Fish fillets
• Shrimp
• Prawns
• Krill
• Insect-based predator foods
• Quality carnivore pellets if accepted

---

🚫 Avoid Routine Live Feeder Fish

Although Tiger Fish naturally prey on fish:

LIVE FEEDER FISH ARE NOT NECESSARY

Routine feeder-fish use can introduce:

• Parasites
• Bacteria
• Disease
• Nutritional deficiencies

Whenever possible, condition the fish to accept:

• Frozen foods
• Prepared predator foods
• Quality whole-food alternatives

---

⚠️ Do Not Overfeed

Large carnivores can easily be overfed in captivity.

Overfeeding increases:

• Obesity risk
• Water pollution
• Nitrate
• Organic waste

Feed according to:

• Fish size
• Body condition
• Water temperature
• Growth stage

---

🐟 Predator – Not a Normal Community Fish

Any fish small enough to fit into the Tiger Fish's mouth should be considered:

POTENTIAL PREY

Do not rely on apparent peaceful behavior from a juvenile.

Predatory behavior increases dramatically as the fish grows.

---

👥 Social Behavior – Important Correction

The older page simply calls the African Tiger Fish:

AGGRESSIVE AND TERRITORIAL

That does not fully describe its natural behavior.

Scientific observations indicate:

SMALLER AND MEDIUM-SIZED TIGER FISH FORM ROVING SCHOOLS OF SIMILAR-SIZED INDIVIDUALS

while:

THE LARGEST ADULTS BECOME MORE SOLITARY

---

🐟 Juveniles

Young Tiger Fish naturally benefit from the presence of:

SIMILAR-SIZED CONSPECIFICS

However, maintaining a group in captivity requires an enormous system.

---

⚠️ Size Matching Is Critical

Smaller Tiger Fish may become:

PREY

for substantially larger individuals.

Do not combine dramatically different sizes.

---

🏠 Group Housing

A group requires:

MUCH MORE THAN 650 GALLONS

because every additional fish requires:

• Swimming space
• Feeding space
• Oxygen
• Filtration capacity

A true adult group is generally better suited to:

PUBLIC-AQUARIUM-SCALE OR CUSTOM SYSTEMS

---

🐠 Tankmates

Tankmate selection is extremely difficult.

Potential companions must be:

• Too large to swallow
• Extremely robust
• Comfortable in open water
• Compatible with high flow and high oxygen
• Not overly aggressive toward the Tiger Fish

---

⚠️ “Too Big to Eat” Is Not a Guarantee

Even a fish too large to swallow can potentially be:

• Bitten
• Chased
• Injured
• Stressed

A species-only setup is often the easiest way to reduce compatibility problems.

---

🦷 Feeding Safety

Because the Tiger Fish has exposed, interlocking teeth:

DO NOT HAND FEED

Use:

• Long feeding tongs
• Appropriate feeding tools
• Safe feeding techniques

especially with large specimens.

---

🛡️ Aquarium Maintenance Safety

Before placing your hands in an aquarium containing a large Tiger Fish:

• Know exactly where the fish is
• Avoid trapping it
• Avoid sudden movements
• Use dividers when necessary
• Never intentionally provoke a feeding response

---

🚑 Handling

Large Tiger Fish should not normally be:

HANDLED DIRECTLY

Moving one may require:

• Large rigid containers
• Heavy-duty fish bags
• Large transport tubs
• Professional handling equipment

Their combination of:

• Speed
• Strength
• Teeth

makes improper handling dangerous to both the fish and keeper.

---

♂️ Male vs. Female

Sexual dimorphism is not especially useful for normal aquarium sales.

Scientific records indicate that:

MALES CAN REACH GREATER MAXIMUM SIZE

with FishBase documenting:

• Male/unsexed maximum: approximately 105 cm fork length
• Female maximum: approximately 74 cm fork length

Juveniles generally cannot be reliably sexed by appearance.

Unless confidently identified:

SELL AS UNSEXED

---

🥚 Reproduction in the Wild

The African Tiger Fish is:

OVIPAROUS / EGG-LAYING

and reproduction is associated with seasonal changes in river conditions.

---

🌧️ Rainy-Season Spawning

Wild spawning is associated with:

RISING WATER DURING THE RAINY SEASON

Adults move into suitable spawning areas as rivers and floodplains expand.

---

🌿 Shallow Vegetated Spawning Areas

Eggs are associated with:

• Flooded vegetation
• Shallow marginal habitat
• Seasonally inundated areas

Young fish initially use these vegetated areas for:

• Food
• Protection
• Nursery habitat

---

🐣 Juveniles

As floodwaters decline, young Tiger Fish move progressively into:

• Larger channels
• Deeper water
• Permanent river habitat

---

🥚 Captive Breeding

African Tiger Fish are:

NOT A ROUTINELY CAPTIVE-BRED HOME-AQUARIUM SPECIES

Their natural reproductive cycle involves:

• Seasonal floods
• Large migration areas
• Vast volumes of water
• Floodplain nursery habitat

Do not advertise this species as:

AN EASY AQUARIUM BREEDING PROJECT

---

🌎 Conservation Status

The current global IUCN assessment classifies:

Hydrocynus vittatus AS LEAST CONCERN

The updated assessment date is:
