Hello,

I am setting up an arowana tank and would like some advice.

What color or type of substrate is best?

What fish can I put in the same tank? Severums?

What plants can I add?

How many Arowana can I keep in one tank?

How much water flow do they need?

Is 125 gallons ok?

Temperature?

Has anybody had success maintaining a breeder tank for feeder fish? How large?

Thank you for your time
Larry

IMO, there is really no domestic aquarium suitable for Arowana.

The recommended minimum is 200G (750 Litres), but much bigger is much better. The Arowana can grow to over 1 metre long (about 3' 5").

There's a profile for this spectacular fish here on fishlore: https://www.fishlore.com/profiles_silver_arowana.htm

I would recommend (as the profile does) to leave these beauties in the wild unless you can provide a huge tank, great filtration and really look after it.

There are different sized arowanas, so i would be looking at getting the smallest one (jardini? theres one that stays under 2 feet, im pretty sure), but even thats gonna outgrow a 125. as ryan said, the big ones (black arowana) get huge and are not suitable for all but the biggest home aquariums, aka custom built 400+ gallons.

there is a plethora of info on the internet - most of the questions youve asked can be answered with a google search. for more specific questions, you can look at monsterfishkeepers.com. many people there have huge custom built tanks that hold real tankbusters, arowanas included.

Thank you for your posts. But is there anyone that could speak from experience of owning one of these fish? I will buy an arowana and I need to know the best way of taking care of it because I have really grown to adore this fish. I dont know if I can afford to buy larger than an 125. but I will try to go for a 180gal. i would appreciate if you can answer any of my questions I posted.

Thanks
Larry

You don't need the super big tank right away, but that time will come.

There are a few people here that keep them, but as I said you ought to look at monsterfishkeepers.com.

a 125 G is enough. just as long you have more than enough filtration and very far from the point of overstocked.

there are many variables on how a aro. will grow, its growth rate. from what ive seen from all the asian LFS in seattle, wa; a full grown aro. will most def. survive and be happy in a 125 G, with proper filtration.

at one point i was about to buy a 200 G for over 400 bucks at a asian LFS.
the owner told me to settle for a 125 G.
now, he couldve made a few extra bucks off me and have sold a tank; but he did not.
he said: buy a 125 G from me for 325, or buy a used tank for even less.

What kind of Arowana are you getting? If you are in the US,Jardini,African,and Silver or Black are the only ones legal.

Jardini stay the smallest,but a 125 is not big enough. You will need at least a 30 inch wide tank,and 6 to 8 feet long.Jars are very aggressive,and will often kill anything else in the tank.

African Aros need a 8x4 foot tank to be housed for life.The are also very picky eaters(filter eaters),and not recommend for beginners.

Silvers and blacks will be fine in a 180 for 2 or 3 years,but will also need a very large tank to be housed for life. A good rule for them is,twice the length of their body,and with a few inches wider than their maximum length. So a 8x3 is what you will need for life.

Asian aros have the most color,but are illegal in the US. If you do not live in the US,you will pay big bucks for one. They get to be around the same size as a Jar,so they will need a similair sized tank.

Aros are great fish. I have a silver myself. But in order to keep them healthy for life,you need the room for a huge tank,the room to keep the tank in,and the money to get it. If you have 5 or 6 grand to spend on a tank for 1 fish,go for it!

They are top swimmers,so substrate does not matter.

Severums would probably work. Eartheaters usually are fine too. It depends on the fish though. Any and all tank mates could be food.

Any plants,live or fake are fine.

Depends on the size of tank. A 450 to 500 gallon, 3 or 4 aros. Bigger the tank,the more fish you could keep.

Slower flow on the top of the tank is best.

125 will work for a grow out for 12 to 18 months at most,depending on the type of aro it is. It is not even close to being big enough for life.

79 to 82 degrees.

Don't give them feeders.You will never get them off them,and if they are use to eating live food,they are sure to eat any tank mates,which it sounds like you would like to keep with one. Give them good quality freeze dried mysis,krill,blood worms,flakes when small. Then get them onto pellets as they grow.

reducing stress, keeping a silver arowana happy should be your main approach, which in turn helps the arowana be comfortable and happy.

whatever it takes, do it.
keeping a sil aro. in a 400 G is always good, but no need if having just 1 arowana.

125 gallon tanks are 18 inches wide. A silver aro will grow to 32 to 36 inches. A 8x3 tank is needed to house one for life. 18 inches is just not enough room to turn.They will eventually start to swim backwards,get gill curl,get stunted,and die pre-maturely.

until that time comes, no need to speculate.

A healthy aro. will turn just as how a hand with its second knuckle clenched and then moving the fingers downward.

i witness my arowana doing her turns all the time.
---
my silver arowana at 3" cost me 30 bucks when i first brought her home.
since then, ive spent about 500 bucks, not including the new tank; to plan for her happiness.
this is how im so dedicated to my arowana's comfort.
ive removed so much: duckweeds, driftwood, a 3rd filter, a bullying fish; just for her.
im not implying that monetary unlimitness is a point of impressiveness, what im saying is:

im giving first hand experience. just as the OP is asking for.
whether it may be wrong, the wrong approach or just plain inhumane.

im giving my 2 cents.

I'm not speculating on anything. I have a 450 gallon tank,96x36x30,that I spent thousands,not hundreds on,that I have 1 silver(34in) and 2 black aros(26&30in) in. I myself,along with others I know,made the mistake of thinking a 125,or 150,or even 180 or 220 would be large enough for a aro for life. They are not. The aros do not have enough room to turn,grow,and live.They do get gill curl,get stunted and die. I'm sorry to tell you,but your 125 is not big enough to house your fish for much more than a year or 2. I'm not giving my 2 cents,I am giving years of experience,FWIW.

At least on this one I agree with you 100% Nitro. There's no way 125gal is big enough to permanantly house any Arrowana. Very accurate info about the consequences of keeping such a large fish in a tank that's too small for it to.

Good morning.

Rude comments and arguing will not be tolerated! I suggest you both agree to disagree and let it go at that.

Great info above. But I wouldn't suggest adding anything else in the tank except for the Arowana itself because they create a lot of waste and in turn whatever you have in there such as plants, substrate or decorations will get dirty and it wouldn't look nice. So a tank without anything would do nicely

Severums would probably work. Eartheaters usually are fine too. It depends on the fish though. Any and all tank mates could be food.
As long as the fish is big enough not to fit into the Aro's mouth then it should be fine

I think anyone that is daring enough to house an arowana will know when it is too big for its tank. I'd just recommend you prepare for that day by saving money for a bigger tank or make plans to sell it

Well. I just want to thank everyone for being honest and giving their info to me. You have convinced me to buy a 180 gallon 6'x2'x2' (i beleive)

I know you all say to go larger but at the moment that wouldnt be anything short of absurd for me. If I see that the arowana is having a difficult life in there I will think about taking him or her out when the time comes. I am looking forward to growing the fish out. So i want to buy one small.

I have decided to go with Tahiti moon sand so that I can add a stingray.
How many pounds of sand would be good for a 180gal tank? I may order 300 pounds but that sounds like alot. Any more advice you can share?
Is drift wood ok as a decoration? What decor do you have?
Filtration?

Driftwood is fine for decoration & some large leaf floating plants will be much appreciated to. Something like Water Lettuce should work well. Unless you are planning on having substrate rooted plants, 150lb of sand should be plenty. I used 120lb of a fine grained sand in my 6x2x2ft & that gave me a bit about 1 1/2" deep substrate. I've got a fair bit of wood in there that displaces some of the sand, meaning it is a bit deeper than if there were no decorations. There's no way you will need more than 200lb though, even with substrate rooted plants.
