I just bought myself a 120 gallon aquarium (5ftx2ftx1.5ft) and i was thinking about what stock i should get. I have always wanted to keep an arowana and would a jardini arowana do well in the long term in my new tank?
Jardini arowana
- Thread starter Thushar
- Start date
They get over two feet long, 36" in the wild. No, a 120 would not be a suitable long term tank for one. Thats like keeping a whale in a backyard swimming pool.
The Jardini is the smallest of the family of the Arowana and they only get 24 inches. The Asian can get to 36 and the silver which is biggest of the family can get up to 4 feet.
I have similar question can Jardini that can get up to 2 feet be able live in a 125 gallon tank. When I researched before purchasing it did say a 125 is the min tank that Jardini can live in. but now even people that actually know the really full size Jardini at 24 in then need a bigger tank. So which one has correct answer
That's my opinion. Yes google can turn up 125 gallons being suitable, but I don't feel that it is either fair or suitable to a fish that hits 24" in length. You could probably get away with a 240 gallon if it's the proper size but even then I'd still prefer a 300+ tank.
Can someone that actually owns a full grown Jardini Arowana answer this question
Jardini have the potential to grow to approximately 3' but most jardini in home aquariums grow to about 24". My Jardini is in a 240g (8'x2'x2') and is about 20" TL. He doesn't jump and eats like a pig but he doesn't allow anything else with him. While I could keep him there for the rest of his life (unless he grows past 26") I do want to build a larger tank so I can try to keep several different bottom dwellers with him.
It is important to note though that all other species of aside from silvers and blacks tend to grow bulky instead of longer. This makes a jardini less flexible than a silver or black of similar length.

Ah I forgot to answer OP's question directly. IMO with those dimensions you technically won't run into any problems. In terms of long term health, if you do consistent water changes and keep it bare bottom with no other tank mates you could pull it off. Again, IMO, a 180g is the absolute minimum I would keep one but with those tank dimensions you are only really missing that extra foot of swimming space with your 120 (assuming your sizes are length x width x height if not then don't get one). Health wise that doesn't really matter as long as you do regular water changes and keep the environment stress free so it doesn't jump.
Regardless of what you do, please do think about your situation carefully. While I'm not out right condemning or promoting a decision I do want to stress that a 120 is not really an ideal minimum tank size. If you really want to keep a Jardini in a 120g then it will require a lot of maintenance.
