arowana in a 55gallon tank?

Question

hi i have a 6" golden arowana rite now but i am wondering if its OKAY for him to be in a 55 gallon tank when he is a adult???

Answer 1

The above poster is right, you need longer then the fish in every dimension of the tank. I would suggest 50% longer as a minimum personally. That would mean for a 20" arowana at least 30" on each direction. Of course, you would want one of those to be significantly more so he has swimming room, maybe more like 8' X 30" X 30" which is about 375 gallons or so, but the gallons is less important than the measurements.

Answer 2

Is this a joke?
Do you know how bit those things get?

In case you don't,
They can get up to 48 inches long! Of course, those are wild caught maximum sizes, tank arowanas get to be around 35 inches. Even so, a 55 gallon is 48 inches long, so a full grown arowana would not be able to turn around.

Most sources recommend a minimum length of 6 feet for an arowana. A minimum depth of 2 feet would be required as well, but I would be hesitant to keep a full grown arowana in a tank so small. Anything under 150 gallons is basically not very good for the fish.

Arowanas are one of the largest freshwater fish. They get huge, and really should not be kept in a normal sized home aquarium. Your tank is far too small. He'll be in fine for a while, but not long.

I've added links to a couple useful sites in case you want to read more. Ok well, I've been trying since about 2 minutes after I posted that to post the above information and add the links. Unfortunately, if I try to add links, I get the dreaded 999 error and my post won't upload. The two websites are badmanstropicalfish (. c o m) and aquariumlore.blogspot (.c o m) you might be able to get them up on google

Answer 3

In my experiences in owning a couple silver arowanas, it would not be a optimal tank for an adult arowana (of any species). As you know, they can grow kinda long. Even though you hear people saying that a small tank would just inhibit the growth (stunted) of the arowana, it is actually not really true. Your arowana would grow if properly cared for and would show signs of overgrowth. My very first arowana had grown to about 13 inches and can see the stop of further growth. I thought it was okay, since nothing was really bad about it. But then it's gills started to curl. I researched it and the cause of it was outgrowth of the tank.

you can keep it in that tank for like at max 1 year. But after that try upgrading to a bigger tank.

Hi There,

I am not an expert in arowana but when i wanted to start the hobby I was told by the pet shop owner that bigger tanks will encourage growth. If the arowana do not have enough space it will stunt its growth.

The rule of thumb for this according to him( he has over 30 in his private collection) is to have at least 50% more in length for the fish in length and 20% in width.

Sorry i cannot be more specific in gallons but if the fish is 6" then going by his calculations min 12" in length and around 8" in width.

Feeding life food would be desireble. Arowana's will get its colour with life food. Crickets, frogs, centipede, roaches is always recommended altenated with life small fish.

Good luck. I hope this answer will help

Answer 5

Here in Aisa the minimum tank size for an arowana is normally 4'x2'x2' or about 450 litres. Like in a pervious post I answer, the glass has to be 8mm and above as this is a very strong fish.

You can have a grow out tank for it initially, say about 3'x1.5'x1.5' (190 litres) until he's about a foot long.

Answer 6

You need a swimming pool just for them.
