Granite Snakehead (Channa cf. limbata 'Granite')

Choose a granite snakehead for a predator tank of its own

The granite snakehead takes its name from its coat: an irregular, speckled pattern of dark brown and orange-gold blotches that looks like a slab of polished stone. The long dorsal and anal fins carry rows of orange dots, and the rounded tail is spotted orange on a dark ground. Underneath the pattern is a classic snakehead: a long, cylindrical body, a broad head with a wide mouth, and the habit of hanging still among cover before striking at food. It is sold as Channa cf. limbata 'Granite', a dwarf snakehead, and it is a predator from first to last.

Buy one if you want a single, interactive fish that learns its keeper and its feeding routine, and you are happy for it to have the tank to itself. Do not buy one for a community tank of small fish: anything that fits in its mouth will be eaten.

Read the label

Why the uncertainty? Seriously Fish treats C. gachua as a probable complex of similar species and still lists limbata as a synonym, and FishBase files it the same way. A 2017 DNA study by Conte-Grand and colleagues found an eastern lineage, running from Myanmar to Vietnam, southern China, Malaysia and Indonesia, and proposed Channa limbata as its name for now. Granite is one of several trade forms sold under that name; its exact origin is not published.

Compare it with other snakeheads before you choose

"Snakehead" covers fish from palm-sized dwarfs to river giants, and choosing the wrong one is the commonest mistake. The figures below come from Seriously Fish and Practical Fishkeeping's quick guide to snakeheads.

In our range, the Blue Rainbow Snakehead, the Rainbow Snakehead and the Assam Dwarf Snakehead sit at the small end with this fish, while the Ocellated Snakehead and Dusky Snakehead need far bigger tanks. Browse every snakehead for sale, our Channa range, the other fish category and the oddball fish collection, which also includes the Malabar Snakehead.

Check what you receive

One purchase supplies one live granite snakehead in the standard size we stock, sold young rather than as an adult. Its sex is not known: snakeheads are hard to sex, and Seriously Fish notes only that males of this group tend to have longer dorsal and anal fins while females grow larger and deeper-bodied.

The pictures show the pattern type, not the individual. No two granite patterns are the same, and the contrast changes with mood, lighting and age; a fish that has just travelled is often darker or paler than it will be once settled. Expect the speckled granite look, not a match for every blotch in the photograph.

Keep it legally: indoor aquaria only

Before you order any snakehead, check where you live. In England and Wales, the government guidance on keeping non-native fish links to a checklist of freshwater fish that may be kept for ornamental purposes under a general licence (version 7, last updated 13 October 2026). The checklist includes the genus Channa, except Channa argus (the northern snakehead) and its subspecies. A granite snakehead can therefore be kept without applying for an individual licence.

The same checklist says these fish may be kept in indoor aquaria only. A pond, a patio tank or a conservatory pool open to the outside is not covered, and releasing any aquarium animal is illegal. Scotland and Northern Ireland set their own rules: OATA reported in 2017 that every Channa is restricted in Scotland and needs a licence, so customers there should check the current position before buying.

Size the aquarium for the adult

Plan for a fish of about 20 cm. Seriously Fish gives a maximum of 200 mm standard length for the gachua group, Practical Fishkeeping gives 20 cm for the dwarf snakehead, and Ecology Asia describes adult limbata in Singapore at about 20 cm total length. FishBase records the largest fish of the complex at 32.9 cm total length, a reminder that some individuals outgrow the average.

Seriously Fish recommends a base of 120 x 45 cm, about 243 litres, with at least 30 cm of water. Floor space matters more than height for a fish that spends its day lying in cover and patrolling the bottom. Use the tank volume calculator to check real litres and the stocking calculator if you are thinking of adding anything else.

Check three numbers

Furnish a dim, escape-proof home

Snakeheads feel safe in shade. Seriously Fish advises dim lighting, live plants, driftwood, terracotta pipes and pots, and floating plants such as Ceratopteris to cut down the light and reduce hiding. Practical Fishkeeping recommends gravel over very fine sand, which can clog filters. A granite snakehead given a den and overhead cover will often sit at the mouth of it in full view; one kept in a bright, bare tank tends to hide all day.

Two things are essential. First, a tight lid: Practical Fishkeeping calls it vital because snakeheads leap well, and Seriously Fish calls the genus escape artists. Second, access to air: these fish breathe through chambers above the gills lined with breathing tissue, and Practical Fishkeeping warns they can drown if kept from the surface. Leave a few centimetres between the water and the lid.

Lay out the tank

Hold the water steady

This group tolerates a wide range, so stability matters more than chasing a figure. Seriously Fish gives 18-28°C, pH 5.0-8.0 and 1-20 dGH for C. gachua in the broad sense; FishBase gives 22-26°C and pH 6.0-7.0. Practical Fishkeeping notes that many snakeheads come from soft water up to 8 GH at pH 5.0 to 7.0, and that northern Indian populations of the dwarf snakehead need a cold winter while tropical ones do not.

Start from your tap

UK tap water can be anything from soft to very hard. Test yours first, then keep every water change the same. Our guide to water chemistry explains the readings, and the water matcher checks your tap water against this fish's range.

Keep waste under control

Predators fed on prawn and mussel produce heavy waste, and a mature filter is the only thing between that waste and the fish. Seriously Fish suggests a filter turning over four to five times the tank volume an hour, about 970 to 1,215 litres an hour for a 243-litre tank, and a heater of around 150 to 250 watts in a room near 20°C. Read our nitrogen cycle guide before the fish arrives, and our filtration guide to choose equipment.

OATA's care sheet for aggressive fish asks for at least a 25% water change every week and weekly tests of ammonia, nitrite, nitrate, pH and hardness. Practical Fishkeeping cautions that many snakeheads react badly to large or sudden water changes. Stick to steady weekly changes of about a quarter, matched for temperature, rather than occasional big ones.

Weekly checklist

1. Test the water.
2. Remove uneaten food and siphon the gravel.
3. Change about 25% with conditioned, temperature-matched water.
4. Rinse filter media in old tank water only.
5. Check the lid and cable gaps.

Feed meaty foods on a schedule

Wild fish of this group feed at night on small fish, insects and crustaceans, according to FishBase. Captive fish learn dead foods readily. Seriously Fish suggests bloodworm, small earthworms and chopped prawn for juveniles, and fish strips, whole prawns, mussels, live river shrimp and larger earthworms for adults, with dry food as an extra rather than the staple. Practical Fishkeeping lists meaty frozen foods, chunks of fish, mussels, shrimp, sinking pellets, earthworms, mealworms and crickets.

OATA's rules for predatory fish are short: use food sized for the fish, feed no more than once a day, and never use live fish as food. Seriously Fish also advises against feeder fish, because of disease risk and poor nutrition, and against mammal and bird meat.

Plan a week of meals

That last line follows Seriously Fish's advice for the related C. andrao, whose adults do not need daily meals. Give only what is taken within a few minutes and remove the rest.

Bring it home calmly

Turn the aquarium light off before you open the box. OATA's floating-bag method works well: float the sealed bag for 10 minutes, add tank water to it gradually over up to 20 minutes, then net the fish into the tank with as little bag water as possible. For fish packed in boxes, OATA describes dripping tank water slowly into the container through airline tubing instead. Keep the lid closed the whole time; a stressed snakehead may jump.

Expect it to hide for several days. Our acclimatisation guide covers the full process.

Plan for a fish that eats its tank mates

Be clear about what you are buying. This is a predator, and the sources only differ on how strict to be. OATA's care sheet for aggressive fish says snakeheads are aggressive towards any other fish and should be kept alone. Seriously Fish recommends a species tank as the usual choice, while allowing peaceful, non-territorial fish too large to eat. Practical Fishkeeping describes dwarf snakeheads as docile with fish they cannot eat, and says small to medium snakeheads do well with medium to large cyprinids, similar-sized catfish and non-aggressive cichlids, but suffer with large, aggressive cichlids.

Ask before you add anything

1. Will it still be too big to swallow when the snakehead is 20 cm?
2. Is it calm enough not to bully a shy predator?
3. Do you have a spare tank if it goes wrong?

Our tank mates tool helps with the first two questions. Young snakeheads can be kept together, but Seriously Fish warns they often turn aggressive as they mature.

Spot problems early and handle with care

A healthy granite snakehead has clear eyes, whole fins, unbroken skin and a fast feeding strike, and rises calmly to breathe. OATA lists clamped fins, flicking against objects and shimmying as warning signs, and advises gloves, careful netting and double bags for toothy predators.

Know how this group breeds

The gachua group are mouthbrooders: FishBase says the male carries the eggs and fry in his mouth, and Seriously Fish notes that in some populations the female lays extra, infertile eggs that feed the fry once they are free-swimming. Practical Fishkeeping's advice for pairing snakeheads is to let several young fish pair naturally in a large tank with plenty of hiding places; both parents then guard the fry in a tight school. Seriously Fish warns that different populations can hybridise, so keep granite with granite.

Answer granite snakehead buying questions

Why is it called a granite snakehead?

Granite is a trade name for the pattern: an irregular, speckled mix of dark brown and orange-gold blotches that looks like polished stone. The fish is sold as Channa cf. limbata 'Granite', a dwarf snakehead of the Channa gachua complex.

Can I legally keep a granite snakehead in England?

Yes, in an indoor aquarium. The government checklist for the ILFA general licence (V7, 13 October 2026) covers every Channa species except the northern snakehead, Channa argus, and its subspecies. It must never go in a pond or be released. Scotland and Northern Ireland have their own rules; OATA reported in 2017 that Channa need a licence in Scotland.

How large will it get?

Plan for a fish of about 20 cm. Seriously Fish gives 200 mm standard length and Practical Fishkeeping 20 cm for the dwarf snakehead group, while FishBase records 32.9 cm total length as the largest fish of the complex.

How big an aquarium does a granite snakehead need?

A base of at least 120 x 45 cm, about 243 litres, with water at least 30 cm deep, as Seriously Fish recommends, and a tight lid that leaves an air gap above the water.

Is a granite snakehead aggressive?

It is a predator that will eat any fish it can swallow. OATA treats snakeheads as aggressive and advises keeping them alone; Practical Fishkeeping calls dwarf snakeheads docile with fish too big to eat. Plan for a species tank.

What do granite snakeheads eat?

Meaty foods such as prawn, krill, mussel, earthworms and carnivore pellets, once a day at most. Never feed live fish, and avoid beef heart, chicken and other mammal or bird meat.

What water does it need?

Clean, steady water at about 22 to 26 degrees C and pH 6.0 to 7.5, soft to medium hardness, with zero ammonia and nitrite. Seriously Fish gives a wider 18-28 degrees C and pH 5.0-8.0 for the group.

Can I keep it with a Lawu snakehead?

Not in the same tank. Snakeheads of the same group are hostile to each other as adults, and Seriously Fish warns that different populations may hybridise, so keep each form on its own.
