Carassius auratus

Captive lifespan reflects typical experience in a home aquarium, not maximum recorded age; genetics, sourcing, and care vary.

Wakin Goldfish Tank Setup
Goldfish need at least 200 litres (53 US gallons) with powerful filtration and cooler water around 50-72°F, pH 6-8. They produce far more waste than most tropical fish, so don't skimp on the filter. They grow to around 30 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 Wakin Goldfish 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.
Wakin Goldfish Tank Mates
Pond-suitable twin-tail goldfish. More active than fancy types. Cold water only; high bioload. The Wakin Goldfish is peaceful, which is the first thing to weigh up when you choose tank mates. At around 30 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 Wakin Goldfish Good for Beginners?
Reasonable early choice after cycling. Buy after the tank has stable ammonia and nitrite readings, not the same weekend you fill it.
Wakin Goldfish - frequently asked questions
What size tank do Wakin Goldfish need?
Wakin Goldfish need a tank of at least 200 litres (53 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 Wakin Goldfish need?
Keep them at 50-72°F with a pH of 6-8, 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 Wakin Goldfish eat?
Wakin Goldfish 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 Wakin Goldfish good for beginners?
Yes - Wakin Goldfish are a reasonable beginner fish once the tank is cycled and parameters are stable. Add them after ammonia and nitrite read 0 ppm, not the same day you fill the tank.
Common mistakes with Wakin Goldfish
- Underestimating tank size - the minimum footprint is 200 litres (53 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
