Malawi Eyebiter Tank Setup
A tank of at least 250 litres (66 US gallons) works well. Keep the water at 73-82°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 25 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 Malawi Eyebiters 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.
Malawi Eyebiter Tank Mates
Requires a large tank and good filtration. The Malawi Eyebiter is peaceful, which is the first thing to weigh up when you choose tank mates. At around 25 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 Malawi Eyebiters Good for Beginners?
Care demand varies by line and setup. Match the care level to how often you actually test and change water.
Malawi Eyebiter - frequently asked questions
What size tank do Malawi Eyebiters need?
Malawi Eyebiters need a tank of at least 250 litres (66 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 Malawi Eyebiters need?
Keep them at 73-82°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 Malawi Eyebiters eat?
Malawi Eyebiters 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 Malawi Eyebiters good for beginners?
It depends on the setup. Match Malawi Eyebiters to how often you actually test water and perform maintenance.
Common mistakes with Malawi Eyebiters
