Arrowana Growth Rates

[@ombomb]

Saw a small one at my LFS yesterday, fantastic little fish just 3" (£17.50).

How soon would one of these need a tank bigger that 50G?

What could they be kept with until that point?

firstly can we astablish which species it was? At that price i'm guessing a silver or black.

is it is silver then do you have the space to house a 3ft fast swimming arowana.

if it's a black then it's only a 6x2x2 minium tank you need. I'm thinking a 50g is a meduim sized 4ft tank right? In which case I would say it could stay in there for about 6-8months. Whats the exact dimensions of the tank in question?

Did you notice a yellow sac hanging from it's belly? (egg sac) if it still has this attached you shouldn't buy one, if you do decide to buy one then be very picky about which 1 you have making sure it's in perfect condition. At this size it's very risking buying arowanas, it's usually best to try anf find one at atleast 6".

Hi @ombomb......Ours is an Australian Pearl (Jardini) and was bought about 2 month ago ...when we got him he was approx 8" and now he is about 1/2" off 1ft....we can notice changes all the time, he is really chunky too...let us know if u get one and post what kind it is that you saw in ur local Lfs ...gud luck

Basicly unless you have at least a 6x2x2 tank then dont even think about an arowana, all species grow fast and will be around a foot within the first 8 months, growth then slows to around a inch a month until they hit 2 feet and then it slows further. You can expect any species to reach at least 2 feet within 2 years and silver arowanas will grow to at least 3 feet eventually.

That's what I thought, it was just such a cool fish.

Well it's on the list with the Rays for when I get the dream tank(s)!

Yes it was a Silver BTW, surely they don't reproduce at 3 inches do they?

 

[Paul_MTS]

they sure do!

at 3", sometimes in shops you will see them with there egg sacs still attached, this is because they are still extremely young and still using the egg sac as food.

just found this site about arowana young..

http/dragonfish.com/fry.htm

although this is for a asian arowana so the young are more kind of fry size.

i did a lil research on the a few weeks ago just out of curiosity, and iv heard that its best for them to starte out in the size tank that they will need once they are adults in order for them to maintain a steady rate of growth rather than haveing to stop and go because of teh changes in tank size.

i would like to know what are the max size for asian austrialian and jardin aros and what size tanks they would be best in

 

[CFC]

Scleropages jardini is one of the Australian arowanas. Both Australian arowana species can be expected to reach at least 2 feet in length and can grow as large as 2.5 feet, the minimum tank size for one would a 6x2x2 (180 US gallons) though obviously much larger would be better.

 

[Ethos]

How many gallons would that be for 2 then?

 

[CFC]

You can't keep two arowana's in one tank. To keep multiples you would need at least 5 arowana's and a tank of 1000 gallons or more, unless you were able to buy an established breeding pair of which you have more chance of shoveling up rocking horse dung.

 

[jarcher1390]

but its not impopsible

 

[Ethos]

Yeah, but I dont know anyone with 1000G tank laying around...I wish I did.
