African Snakehead Tank Setup
A tank of at least 280 litres (74 US gallons) works well. Keep the water at 79-86°F with a pH around 6.5-7.5, and set up both cover and open swimming space where they spend most of their time (Mid). They grow to around 45 cm, so plan the tank size and filtration for a full-grown adult rather than the small juvenile you see in the shop.
What Do African Snakeheads Eat?
They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.
African Snakehead Tank Mates
Requires a large tank and good filtration. The African Snakehead is peaceful, which is the first thing to weigh up when you choose tank mates. At around 45 cm fully grown, it needs tank mates that can hold their own against its size and appetite. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are African Snakeheads Good for Beginners?
Care demand varies by line and setup. Match the care level to how often you actually test and change water.
African Snakehead - frequently asked questions
What size tank do African Snakeheads need?
African Snakeheads need a tank of at least 280 litres (74 US gallons). A bigger tank is always easier to keep stable, and gives them more room to settle in and behave naturally.
What water parameters do African Snakeheads need?
Keep them at 79-86°F with a pH of 6.5-7.5, steady rather than chased to an exact figure. In a cycled tank, ammonia and nitrite should both read 0 ppm, with nitrate kept low through regular water changes.
What do African Snakeheads eat?
African Snakeheads are omnivores and aren't fussy eaters. Feed a varied mix of good-quality dry, frozen, and gel foods, and match the food size to their mouths. Feed small amounts once or twice a day, and remove anything they don't eat.
Are African Snakeheads good for beginners?
It depends on the setup. Match African Snakeheads to how often you actually test water and perform maintenance.
Common mistakes with African Snakeheads
- Underestimating tank size - the minimum footprint is 280 litres (74 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
- Cool tap water - this species needs 79-86°F; cold acclimation suppresses immune response and often triggers disease outbreaks.
