At 6–7 cm, this juvenile is still small, but it will grow into a powerful, territorial fish with a strong feeding response and plenty of character. This is not a community fish in the usual sense; it is best appreciated in a carefully planned species setup or with very robust tank mates in suitably large aquaria.\u003c\/p\u003e\u003cp\u003eWith its elongated body, broad head and attractive mottled patterning, \u003cem\u003eChanna asiatica\u003c\/em\u003e makes a dramatic display fish. It is also an air-breathing species, meaning it can gulp atmospheric oxygen when needed, which helps it cope with lower-oxygen conditions than many other fish. That said, it still thrives best in clean, well-maintained water with stable parameters and plenty of cover.\u003c\/p\u003e\u003cp\u003eWe offer healthy, carefully acclimatised stock with \u003cstrong\u003efast UK delivery\u003c\/strong\u003e and a \u003cstrong\u003elive arrival guarantee\u003c\/strong\u003e, so your new fish arrives in the best possible condition. Because this species is a predator and can be territorial, please ensure you have a secure lid and an appropriate setup before ordering.\u003c\/p\u003e\u003ch2\u003eCare at a Glance\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eRecommendation\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific name\u003c\/td\u003e\n\u003ctd\u003e\u003cem\u003eChanna asiatica\u003c\/em\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon name\u003c\/td\u003e\n\u003ctd\u003eChinese snakehead\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCare level\u003c\/td\u003e\n\u003ctd\u003eModerate to expert\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003eSemi-aggressive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdult size\u003c\/td\u003e\n\u003ctd\u003eTypically 25–35 cm, depending on strain and conditions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum tank size\u003c\/td\u003e\n\u003ctd\u003e250 litres for a single fish; larger for pairs or groups\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature\u003c\/td\u003e\n\u003ctd\u003e20–26°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH\u003c\/td\u003e\n\u003ctd\u003e6.0–7.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eCarnivorous; live, frozen and prepared meaty foods\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e8–12 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTank region\u003c\/td\u003e\n\u003ctd\u003eMiddle to bottom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eOrigin \u0026amp; Natural Habitat\u003c\/h2\u003e\u003cp\u003e\u003cem\u003eChanna asiatica\u003c\/em\u003e is native to southern China and parts of neighbouring regions, where it inhabits slow-moving rivers, canals, ditches, ponds and marshy waters. In the wild, it is often found in heavily vegetated areas with soft substrates, submerged roots and plenty of hiding places. These habitats can be warm, shallow and oxygen-poor, which is one reason snakeheads are such adaptable survivors.\u003c\/p\u003e\u003cp\u003eUnderstanding the natural habitat is key to successful long-term care. This species prefers calm water, subdued lighting and a layout that offers security. Dense planting, driftwood, caves and leaf litter all help recreate the sheltered environments it would naturally use for ambush hunting and resting. Although hardy, it should not be kept in poor water quality; regular maintenance is essential for health and colour.\u003c\/p\u003e\u003ch2\u003eTank Setup \u0026amp; Water Parameters\u003c\/h2\u003e\u003cp\u003eA secure, escape-proof aquarium is absolutely essential. Snakeheads are strong, inquisitive and capable of jumping, especially when startled. A tight-fitting lid with no gaps is a must. For a single adult, a tank of at least 250 litres is recommended, with a longer footprint being more useful than height. More space is always better, particularly if you plan to keep a pair or attempt a carefully managed breeding setup.\u003c\/p\u003e\u003cp\u003eUse a soft, natural aquascape with plenty of cover. Good options include bogwood, rockwork arranged securely, caves, PVC shelters hidden among decor, and robust plants such as Java fern, Anubias and floating species. Floating cover can help reduce stress by dimming the light and making the fish feel secure. Gentle filtration is ideal, but the system should still provide excellent biological capacity and regular water movement without creating excessive current.\u003c\/p\u003e\u003cp\u003eKeep the water temperature between \u003cstrong\u003e20 and 26°C\u003c\/strong\u003e, with stable conditions being more important than chasing a precise number. A pH of \u003cstrong\u003e6.0 to 7.5\u003c\/strong\u003e is suitable, and soft to moderately hard water is generally acceptable. Ammonia and nitrite must always remain at zero, and nitrate should be kept low through routine water changes. Because this species is a carnivore and can be messy at feeding time, good filtration and maintenance are especially important.\u003c\/p\u003e\u003cp\u003eWhen introducing a new fish, dim the lights and allow it time to settle. Newly imported snakeheads may be shy at first, but once comfortable they often become confident and highly responsive to feeding. Avoid sudden changes in temperature or water chemistry, and never house this species in an uncovered aquarium.\u003c\/p\u003e\u003ch2\u003eFeeding Guide\u003c\/h2\u003e\u003cp\u003e\u003cem\u003eChanna asiatica\u003c\/em\u003e is a carnivorous predator with a strong appetite. In the aquarium, it should be offered a varied diet of high-quality meaty foods. Suitable options include frozen bloodworm, krill, mysis, chopped prawns, mussel, lancefish and other marine or freshwater meaty items. Many individuals will also accept sinking carnivore pellets or sticks once settled, which is useful for balanced nutrition.\u003c\/p\u003e\u003cp\u003eYoung fish may feed more frequently, while adults can usually be fed every 2–4 days depending on size, temperature and body condition. Overfeeding should be avoided, as snakeheads can become overweight if offered too much rich food. Variety is important: relying on a single food source is not ideal for long-term health. If feeding live foods, ensure they are from a reputable source to reduce the risk of parasites or disease.\u003c\/p\u003e\u003cp\u003eBecause this species is a predator, it may strike at anything that fits into its mouth. Feed with care and never assume tank mates are safe simply because they are active or fast. Remove uneaten food promptly to maintain water quality.\u003c\/p\u003e\u003ch2\u003eTank Mates \/ Compatibility\u003c\/h2\u003e\u003cp\u003eThis is a semi-aggressive predatory species, so compatibility must be approached cautiously. The safest option is a species tank. In very large aquaria, some keepers successfully house \u003cem\u003eChanna asiatica\u003c\/em\u003e with robust, similarly sized fish that are too large to be swallowed and not easily intimidated. Even then, individual temperament varies, and introductions should be monitored closely.\u003c\/p\u003e\u003cp\u003eSuitable companions, where space allows, may include large, sturdy fish such as big barbs, large danios, selected catfish or other tough species that can tolerate similar water conditions and are not likely to nip fins. However, there is always risk. Smaller fish will almost certainly be eaten, and delicate species will be stressed. In many cases, the best practice is to keep this fish alone or in a carefully managed pair if breeding is intended.\u003c\/p\u003e\u003cp\u003eDo not mix with shrimp, small snails or ornamental invertebrates, as these will usually be treated as food. Avoid slow-moving fish, long-finned species and anything that cannot defend itself. If you are unsure, choose a species-only setup.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Tropical Fish Co\u003c\/h2\u003e\u003cp\u003eAt Tropical Fish Co, we understand that live fish need more than just a box and a label.
