Golden Julie Tank Setup
Give them at least 70 litres (18 US gallons). Cichlids are territorial and produce plenty of waste, so strong filtration and some rocks or wood to break up sight lines both help. Aim for 75-81°F and a pH around 7.8-9.
What Do Golden Julies 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.
Golden Julie Tank Mates
Lake Tanganyika cichlid - needs even harder, more alkaline water than Malawi species; very sensitive to poor water quality despite being genuinely hardy once established. Forms stable pair or small-group bonds rather than loose shoals - do not disturb an established group by adding/removing individuals casually. The Golden Julie is aggressive, which is the first thing to weigh up when you choose tank mates. Good matches come down to the whole stocking list working together - temperature, tank size, and temperament - not any single label. 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 Golden Julies Good for Beginners?
Care demand varies by line and setup. Match the care level to how often you actually test and change water.
Golden Julie - frequently asked questions
What size tank do Golden Julies need?
Golden Julies need a tank of at least 70 litres (18 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 Golden Julies need?
Keep them at 75-81°F with a pH of 7.8-9, 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 Golden Julies eat?
Golden Julies 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 Golden Julies good for beginners?
It depends on the setup. Match Golden Julies to how often you actually test water and perform maintenance.
