Arowana Fish in Malaysia 2026: Iconic Fish, Serious Tank Commitment

Arowana fish are one of the most recognisable ornamental fish in Malaysia. Locally, they are often known as ikan kelisa. They are beautiful, expensive, symbolic, and strongly associated with premium fishkeeping. But that does not mean every home aquarium is suitable for one.

Quick answer: arowana fish can be kept in a home aquarium only when the owner can plan for a very large setup, strong filtration, a secure tank cover, suitable feeding, and long-term care. For most casual beginners or small-tank owners in Malaysia, arowana is not a practical first fish.

Is Arowana Beginner-Friendly?

Question	Practical answer
Is arowana popular in Malaysia?	Yes. It has strong local recognition, especially as ikan kelisa.
Is it a small aquarium fish?	No. Juveniles may be sold small, but adults become large, powerful fish.
Is it suitable for a casual beginner?	Usually no. It needs serious planning.
Is it suitable for a prepared hobbyist?	Yes, if the owner has space, budget, filtration, a secure lid, and long-term commitment.
Is it a good impulse purchase?	No. The adult fish, not the baby fish, should decide the setup.

The better question is not “Can I buy an arowana?” The better question is:

Can I house, feed, cover, filter, and maintain this fish properly for years?

Why Arowana Fish Still Get Attention in Malaysia

Arowana is not just another colourful aquarium fish. In Malaysia, ikan kelisa is often linked with wealth, status, luck, and premium ornamental fish culture. Some buyers are attracted by the body shape, metallic shine, scale pattern, colour development, and the “dragon fish” image.

Malaysia also has a real local arowana context. Publicly visible seller listings show juvenile arowana offered in inch sizes, often with prices that can range from hundreds to over a thousand ringgit depending on variety, size, and stated quality. Malay coverage has also discussed arowana as a high-value ornamental fish connected to export, farms, microchips, certificates, and CITES-related traceability.

That makes arowana a good topic for Akuarium.my, but the article should not be treated like a simple “pretty fish profile.” Arowana needs a decision guide because the gap between buying a small fish and keeping an adult fish is very large.

Arowana vs Ikan Kelisa: Are They the Same?

In Malaysia, ikan kelisa is commonly used for arowana. English content usually uses arowana fish, while Malay content usually uses ikan kelisa or ikan arowana.

Common terms you may see include:

• Asian arowana
• Silver arowana
• Golden arowana / kelisa emas
• Red arowana / kelisa merah
• Malaysian Gold
• Bukit Merah arowana
• Blue base / golden base / crossback style names

These names can be confusing because some are common names, some are trade or colour terms, and some are seller or farm marketing terms. Do not judge the fish only by a beautiful name or colour label. Before buying, ask what type it is, how large it may grow, whether documents or certificate details are relevant, and whether the seller can clearly explain its source.

The Biggest Mistake: Judging by Juvenile Size

Many arowana are sold when they are still small. A buyer may see a 4-inch, 5-inch, 8-inch, or 10-inch fish and assume it can live comfortably in a normal aquarium. That is the wrong way to judge arowana suitability.

Depending on type and care conditions, many arowana can grow roughly around 60–100 cm or more. Silver arowana are often described as reaching the larger end of that range, while Asian arowana are also large fish that need serious swimming space.

A young arowana may look manageable in a shop tank, but it should not be treated like a small community fish. The permanent setup should be planned around the adult fish, not the purchase size.

---

Tank Space: Not Every Home Aquarium Makes Sense

Arowana are surface-oriented swimmers with long bodies and powerful movement. They need length, open swimming room, stable water, and enough space to turn comfortably.

A small tank is not suitable for long-term arowana care. A tank that may hold a juvenile temporarily can become unsuitable very quickly as the fish grows. A 60 cm tank, for example, should not be treated as a serious long-term arowana setup.

For Malaysia hobbyists, this matters because many beginner setups are small tanks, starter kits, or decorative home aquariums. Those setups may work for betta, guppies, small tetras, or shrimp, but they are not designed for a large predatory fish.

Before buying arowana, think about:

• adult size, not current size
• tank length and width, not just water volume
• filter capacity and maintenance routine
• whether the tank has a secure lid
• long-term feeding cost
• where the fish will go if it outgrows the current setup

If the answer is “I will upgrade later,” be honest. Many fish are bought with upgrade plans that never happen.

Secure Lid: Arowana Jumping Risk Is Serious

Arowana are known jumpers. This is not a small side issue. Arowana naturally feed near the water surface and can leap powerfully. In an aquarium, jumping can happen because of instinct, stress, poor water quality, sudden movement, aggressive tank mates, or cramped conditions.

A proper arowana setup needs a heavy, tight-fitting lid with no easy gaps. Spaces around wires, filter pipes, airline tubing, and tank corners should be checked carefully. A lightweight cover is not enough for a strong fish.

A secure lid does not replace good care. It works together with:

• stable water quality
• enough swimming room
• calm tank location
• suitable tank mates
• regular maintenance
• avoiding sudden shocks or loud disturbances near the tank

For arowana, a tank cover is not an optional accessory. It is part of the basic safety setup.

---

Feeding: Expensive Fish Also Means Long-Term Food and Water Load

Arowana are carnivorous predators. Their diet can include formulated arowana pellets, frozen foods, shrimp, insects, and other protein-rich foods depending on size and keeper practice.

The important point is not just “what can arowana eat?” It is also:

• Can the owner feed a varied diet without overfeeding?
• Can the filter handle the waste load?
• Can uneaten food be removed quickly?
• Can water quality stay stable over time?

Overfeeding is a common mistake. Some beginners feed heavily because they want the fish to grow faster or look bulkier. That can lead to health problems and water quality issues. Arowana may have a strong appetite, but more food is not always better.

Arowana are not only expensive to buy. They can also be expensive to keep well because food, filtration, water changes, tank size, and long-term maintenance all scale up as the fish grows.

---

Water Quality and Filtration Matter More Than Additives

A large predatory fish creates more waste than a small community fish. Weak filtration, inconsistent maintenance, and overfeeding can quickly turn into water quality problems.

Arowana owners should focus on the basics first:

• strong filtration matched to tank size and feeding load
• cycled biological filtration
• regular water changes
• dechlorinated tap water when using Malaysian tap water
• stable temperature and water conditions
• avoiding unnecessary chemical adjustments unless there is a clear reason

Do not treat vitamins, pH adjusters, tanning lights, or colour-enhancing tricks as shortcuts. For most keepers, stable water and good husbandry matter more than constantly adding products.

Certificate, Microchip and Legal Source: Why It Matters in Malaysia

Arowana is different from ordinary beginner fish because source and traceability can matter. Asian arowana are connected with regulated trade, CITES discussion, microchips, certificates, farms, and export documentation.

For a Malaysia buyer, this does not mean every small arowana listing should be treated the same way. It means you should ask better questions before buying:

• What type of arowana is this?
• Is it farm-bred?
• Is there a certificate or documentation where relevant?
• Is there a microchip number for this fish where relevant?
• Does the seller clearly explain source and variety?
• Is the price realistic for the claimed type and quality?

This article is not legal advice. Regulations and trade requirements can change. If you are buying an expensive or protected/regulated arowana type, verify the source, certificate, and legal requirements with the seller and relevant authorities before purchase.

Who Arowana Is Suitable For

Arowana may be suitable for:

• prepared hobbyists with large tank space
• owners who understand long-term fish growth
• keepers who can maintain strong filtration and stable water
• people who can afford food, equipment, and maintenance
• owners who can secure the tank properly
• buyers who are willing to verify certificate/source information where relevant

Arowana is not ideal for:

• small beginner tanks
• casual impulse buyers
• people buying only because the fish looks lucky or expensive
• owners who cannot upgrade to a large setup
• tanks without a strong lid
• owners who want a low-maintenance display fish
• community tanks with small fish that may become food

Before Buying Arowana in Malaysia: Practical Checklist

Use this checklist before paying for a juvenile arowana:

• Do I know the adult size of this type?
• Do I have a proper long-term tank plan?
• Is my tank long and wide enough for adult swimming space?
• Is the lid heavy, tight, and gap-free?
• Is the filter suitable for a large carnivorous fish?
• Can I maintain stable water quality every week?
• Do I know what the fish is eating now?
• Can I afford long-term food and maintenance?
• Is the seller clear about type, source, and certificate details where relevant?
• Am I buying because I can care for it, not just because it looks impressive?

If too many answers are unclear, wait. Arowana is not a fish to rush.

Better Alternatives If You Are Not Ready

If you like impressive fish but are not ready for a large arowana setup, start with a more suitable aquarium plan first. A well-kept smaller tank is better than a large fish forced into a poor setup.

Depending on your tank size and experience, you may want to read:

• Beginner Aquarium Checklist
• Do Betta Fish Need a Filter?
• Best Aquarium Filter for Small Tank Malaysia
• Best Fish Tank Starter Kit Malaysia
• Best Aquarium Water Conditioner Malaysia

Arowana can stay on your long-term wish list. You do not need to start there.

Yes. Arowana, or ikan kelisa, has strong recognition in Malaysia and is often associated with premium ornamental fishkeeping. However, popularity does not mean it is suitable for every home aquarium.

Is arowana suitable for beginners?

Usually no. Arowana is better for prepared hobbyists who can plan for adult size, strong filtration, secure lids, feeding cost, and long-term maintenance.

Can arowana live in a small tank?

A small tank is not suitable for long-term arowana care. Juvenile arowana may be sold small, but many types grow into large fish that need much more swimming space.

Why do arowana jump out of tanks?

Arowana are natural surface-oriented predators and can jump. In aquariums, stress, poor water quality, small space, sudden movement, and unsuitable tank mates can increase jumping risk.

Does an arowana tank need a lid?

Yes. Arowana tanks should have a heavy, tight-fitting lid with no easy gaps. A secure cover is a basic safety requirement, not an optional decoration.

What do arowana fish eat?

Arowana are carnivorous. Depending on size and keeper practice, they may eat formulated arowana pellets, frozen foods, shrimp, insects, and other protein-rich foods. Avoid overfeeding and remove uneaten food.

Is ikan kelisa the same as arowana?

In Malaysia, ikan kelisa commonly refers to arowana. English pages usually say arowana fish, while Malay pages often use ikan kelisa or ikan arowana.

Do I need a certificate or microchip for arowana in Malaysia?

For certain arowana types, source, certificate, microchip, or farm documentation may be important. Requirements can vary by type and trade context. Always ask the seller and verify legal/source details before buying an expensive or regulated fish.

Final Verdict

Arowana fish are iconic in Malaysia, but they are not casual home aquarium fish. They need space, money, secure equipment, stable water, proper feeding, and long-term responsibility.

If you can plan for the adult fish, arowana can be a serious centrepiece species. If you are still setting up your first aquarium, start with a more manageable fish and build experience first.

Akuarium.my verdict: popular and impressive, but not beginner-friendly for most small home aquariums.
