We all love “Monster Fish.” There is something cool about owning a predator that looks dangerous.
But in Malaysia, owning certain fish isn’t just dangerous for your fingers—it is dangerous for your wallet.
Under the Fisheries Regulations (Prohibition of Import, etc., of Fish), there are specific species that are strictly banned from entering the country. If you are caught importing, selling, or keeping them, you can face a hefty fine (“Saman”) or even jail time.
Why? Because if these fish escape into our rivers (like the Sungai Klang or Tasik Kenyir), they could wipe out our native species.
Here is the list of fish you should avoid, and the legal “look-alikes” you can buy instead.
1. The Piranha (Serrasalmus)
This is the most famous ban.
- The Status: STRICTLY ILLEGAL. You cannot import, sell, or own a Red-Bellied Piranha in Malaysia.
- The Reason: Malaysia has a tropical climate exactly like the Amazon. If Piranhas established a breeding population in our rivers, they would out-compete local fish and pose a danger to humans/livestock.
- The “Fake” Piranha: You will often see a fish called the Red-Bellied Pacu in shops or restaurants.
- Pacu: Legal. Has human-like teeth (eats nuts/fruit).
- Piranha: Illegal. Has razor-sharp triangular teeth (eats meat).
- Warning: Don’t try to smuggle a Piranha. It’s not worth the risk.
- Pacu: Legal. Has human-like teeth (eats nuts/fruit).
2. The “Dragon” Fish (Arapaima Gigas)
The Arapaima is one of the largest freshwater fish in the world. It looks prehistoric.
- The Status: REGULATED / BANNED.
- The Context: While you might see them in huge ponds at zoos or some rich people’s houses, Jabatan Perikanan has stopped issuing permits for import because they are devastating predators. A 3-meter Arapaima eats everything.
- The Alternative: Get a Silver Arowana. It has the same prehistoric “Dragon” look but “only” grows to 3 feet and is legal.
3. The Flowerhorn & Peacock Bass (The “Release” Ban)
This is a tricky category.
- The Status: Legal to Own, ILLEGAL to Release.
- The Problem: The Flowerhorn (Lohan) and Peacock Bass (Ikan Raja) are everywhere. You can buy them in any shop.
- The Crime: The crime happens when you get bored. If you dump a Flowerhorn or Peacock Bass into a drain or lake, you are breaking the law.
- Peacock Bass (Cichla) are aggressive hunters. They have already taken over many mining pools in Perak and Selangor, eating all the local fry.
- Action: If you can’t keep them anymore, give them back to the shop or sell them. Never release them.

4. The Alligator Gar
These look like crocodiles with fins. They are heavily armored and have a snout full of teeth.
- The Status: BANNED.
- The Reason: They have no natural predators in Malaysia. Their scales are so hard that even a Toman usually can’t bite through them. A single released Alligator Gar can decimate a local pond ecosystem.
5. The Crayfish Confusion (Cherax destructor)
Some species of freshwater lobsters (Crayfish/Yabbies) are banned because they carry the “Crayfish Plague” fungus or burrow into river banks, causing collapse.
- Safe Bet: The bright blue/orange Cherax varieties sold in reputable LFS are usually the safe, legal species. Avoid bringing in wild caught ones from overseas trips.
The Bottom Line
Malaysian laws aren’t trying to ruin your fun. They are trying to save our Native Monsters.
We have the Toman (Giant Snakehead), the Sebarau, and the Kelah. These are our national treasures.
If we let Piranhas and Alligator Gars take over, we lose our natural heritage.
Be a responsible hobbyist. Keep it legal, and keep it contained.
