Scleropages formosus
The Albino Arowana (Scleropages formosus) is an aggressive fish that's best left to experienced keepers. Give it a tank of at least 900 litres (238 US gallons), water held at 75-86°F, and a pH of 6-7.5.
Captive lifespan reflects typical experience in a home aquarium, not maximum recorded age; genetics, sourcing, and care vary.

Albino Arowana Tank Setup
Treat 900 litres (238 US gallons) as a starting point - big predators need length, strong filtration, and a secure lid. Hold the water at 75-86°F and pH 6-7.5, and assume anything small enough to swallow will eventually be eaten. They grow to around 90 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 Albino Arowanas Eat?
They're meat-eaters, so feed good-quality frozen or gel foods rather than relying on generic flake. Go easy on portions - leftover protein fouls the water faster than plant foods do.
Albino Arowana Tank Mates
Albino morph of Asian Arowana; requires same care and tank size The Albino Arowana is aggressive, which is the first thing to weigh up when you choose tank mates. It's predatory, so anything small enough to fit in its mouth will be treated as food rather than a companion. 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 Albino Arowanas Good for Beginners?
Not a sensible first purchase. Get the tank cycled, keep easier fish stable for a year, then revisit if you still want the extra work this species demands.
Albino Arowana - frequently asked questions
What size tank do Albino Arowanas need?
Albino Arowanas need a tank of at least 900 litres (238 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 Albino Arowanas need?
Keep them at 75-86°F with a pH of 6-7.5, 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 Albino Arowanas eat?
Albino Arowanas are meat-eaters. Feed good-quality frozen or gel foods rather than relying on generic flake, and don't overfeed. Feed small amounts once or twice a day, and remove anything they don't eat.
Are Albino Arowanas good for beginners?
Albino Arowanas are not a beginner species. They need precise conditions and consistent maintenance, so build experience with hardier fish before keeping them.
Common mistakes with Albino Arowanas
- Underestimating tank size - the minimum footprint is 900 litres (238 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
- Adding to a new tank - Albino Arowanas need a fully cycled, stable aquarium; ammonia spikes in new setups are usually fatal.
