Ikan Toman & Channa Hiasan: Channa Snakehead Care in Aquariums in Malaysia
Channa (snakeheads) are predatory, air-breathing fish with bold patterns and big personalities, and they have a strong following among Malaysian "monster fish" keepers. Most hobby channa are best kept alone, in a tank with a tight, heavy lid, because they jump and climb. Feed them pellets, prawns and other meaty foods rather than live feeder fish. Choose a dwarf species (15–25 cm) unless you can house a very large fish. Malaysian natives like ikan toman can grow to over a metre and are not suited to normal home tanks. Buy only from sellers who comply with Department of Fisheries (DOF) Malaysia rules, and never release a channa into the wild.
Native Malaysian Snakeheads
Malaysians know snakeheads mostly as food fish, which is why searches for "ikan toman" or "ikan haruan" bring up recipes. Scientific checklists record seven snakehead species from Peninsular Malaysia, including:
| Malay name | Species | Adult size | Aquarium suitability |
|---|---|---|---|
| Ikan haruan | Channa striata | ~60–90 cm | Large tank only; mainly a food fish |
| Ikan toman | Channa micropeltes | 1 m or more | Not suitable for home tanks |
| Ikan bujuk | Channa lucius | ~40 cm | Large tank |
| Dwarf snakehead | Channa gachua group (often traded as C. limbata) | ~15–20 cm | Good for aquariums |
| Others | C. bankanensis, C. melasoma, C. marulioides | Varies | For specialists |
About ikan toman hiasan
Baby toman have bright orange and black stripes, so they are sometimes sold as "red snakehead" or ikan toman hiasan. They are fast-growing, aggressive predators that can exceed a metre. Unless you have a huge tank or pond, do not buy a toman as a pet.
Popular Hobby Channa
Hobby channa are often split into dwarf and large species:
| Species | Origin | Adult size | Notes |
|---|---|---|---|
| Channa limbata | South and Southeast Asia | ~15–20 cm | Hardy dwarf; tolerates warm water |
| Channa andrao | India | ~10–15 cm | Small; prefers cooler water |
| Channa pulchra | Myanmar | ~20 cm | Colourful; prefers cooler water |
| Channa bleheri | India | ~15–20 cm | Rainbow snakehead; prefers cooler water |
| Channa stewartii | India | ~25 cm | Generally peaceful for a channa |
| Channa aurantimaculata | India | ~40 cm | Large; orange spots |
| Channa barca | India | ~60–90 cm | Highly prized and expensive; large; seasonal cooling for breeding |
Ask the seller the exact species, its adult size, and the temperature it was kept at.
Channa Care Table
| Factor | What channa need |
|---|---|
| Temperature | Tropical species: 24–30°C. Cooler species (andrao, pulchra, bleheri): about 18–25°C |
| Tank (dwarf) | 2–3 kaki for one fish |
| Tank (large) | 4–6 kaki or bigger |
| Water | Wide tolerance; pH 6–7.5; clean water |
| Lid | Essential; channa jump and squeeze through gaps |
| Temperament | Predatory; often aggressive to each other |
| Diet | Carnivore: pellets, prawns, insects, earthworms |
| Lifespan | 10 years or more for many species |
| Beginner? | Dwarf species, yes for keepers with some experience |
Tank Setup
Lids are not optional
Channa breathe air and can survive out of water for a while. They jump when startled, and they may push light lids aside or squeeze through cable gaps. Use a heavy lid, close all gaps, and keep a small air space under the lid so the fish can breathe at the surface.
Hiding places and layout
- Driftwood, caves and plants (anubias, java fern, floating plants)
- Dim lighting; many channa prefer shade
- Dark substrate or a bare bottom
- Gentle to moderate flow; good filtration is still needed because they eat meaty foods
Solitary keeping
Most channa fight with their own kind. Keep one fish per tank unless you have a bonded pair (which may still turn aggressive). Avoid tank mates small enough to eat. Some keepers add fast, robust fish in large tanks, but many channa are best alone.
Temperature: Warm vs Cool Species in Malaysia
Malaysian homes sit at about 26–31°C. That suits native and tropical channa like C. limbata. But some popular species come from cooler hill streams in India and Myanmar:
- C. andrao, C. pulchra and C. bleheri often struggle long-term above about 26–27°C.
- Keep them in the coolest room, use a kipas akuarium (fan) or a chiller. See our aquarium cooling guide.
- An air-conditioned room helps.
If you cannot cool your tank, choose a tropical species instead.
Water
- Use anti klorin every water change. Malaysian tap water is chlorinated; see our tap water guide.
- Change 25–30% weekly.
- Remove leftover food promptly; meaty foods spoil water quickly.
Feeding
| Food | Notes |
|---|---|
| Carnivore pellets or sticks | Good staple; many channa can be trained to accept them |
| Frozen prawns, krill, mussels | Popular |
| Earthworms and insects | Natural food; use clean sources |
| Frozen fish fillet | In moderation |
| Live feeder fish | Not recommended; risk of disease and parasites |
Feed young fish daily and adults every 1–2 days. Overfeeding causes obesity and poor water.

DOF Rules and Responsible Keeping
Rules on importing, keeping and releasing fish can change, and some states are adding their own rules on invasive species. Buy only from sellers who comply with Department of Fisheries (DOF) Malaysia rules, and check before buying an unusual species. See our prohibited fish guide for the current list of fish you must not keep.
Jangan lepaskan ikan ke sungai
Never release a channa into a river, lake or pond, even a native species. Released predators can harm local fish, and imported species can bring disease. DOF reports about 80 established alien species in Malaysia, and release rules are set by each state: Perlis, for example, now fines people up to RM20,000 for releasing foreign fish into rivers without written permission. If you can no longer keep your fish, give it to a shop or hobbyist.
Common Problems
- Jumping out: secure the lid.
- Not eating: new fish can fast for days. Offer live-like foods such as earthworms, and keep the room calm.
- Aggression: separate fish.
- Fungus or skin problems: usually poor water quality.
