Appropriate Tank Size for an Arowana?

  • We are currently upgrading MFK. thanks! -neo
As I dont own aro's or really know there full tank size requirements, I think this thread is going to help me out.

I talked to the owner of my LFS today and he said a 125 gallon tank that is 6 feet long could house a single aro for its life. Also, the type of aro's he was talking about were jardini if that meens anything.

So what I'm, getting at is, could a jardini live outs its life in the 125 gallon my lfs described to me?

Please trust me on this. 125g with aforementioned dimesion is not suitable to house either silver or jar. If you look at my 30+" silver, you will think double about putting him into a such a tank (please trust me!). As far as Jars are concerned, I've seen a 20" at an lfs and it had to twist itself upward to make a turn. Let's say 24" from front to back (and preferably 8 ft long) should be adequate to house silver aros for minimum of five years or so (my oldest one is four years old at minimum).
 
The average adult length is over 2ft with many reaching the 3ft mark. So, no, a 125 will not be adequate for life in housing a jardini aro. Keep in mind that jars, like all of us, lose flexibility as they age. So, even without further growth, an older jar will need more room to turn than it did at a younger age. A 125's 6ft length is fine. But, the depth (front to back) is very limiting, at 18-20", for housing large active swimmers for life.
 
That sucks, I really wish I could get one. I always had a soft spot for aros and i had never really seen one pclose and swimming around, only pics. Would even a 180 or 150 gallon be enough for life? My lfs only sells/orders tanks that are 180 and under.

I wish so badly I could keep one!

I'll have to ask how wide it is before I order as he didnt tell me.

I dont know why he would tell me that a jardini could live its life in a a 6ft 125.

I asked him what about a 200 gallon and thats when he said I have seen them kept in 125's to 200 gallon tanks.

Thanks to both of you for your help.
 
Probably best to stop thinking in terms of gallons and think of footprint instead. Silvers would need a minimum of 8ft X 3ft (4 ft is more preferable). Jardini aros would need a minimum of 6ft X 30" (3 ft is more preferable). Tank height isn't critical so long as the bulk of the tank's footprint doesn't contain decor that will impinge on the aro's open swimming space.
 
Thank you very much! Thats the info I needed, actualy size instead of gallons. I was thinking I could use sand as the substrate and put some java fern on the bottom maybe? The jardini's at my lfs had amazon swordtails planted in there tank with small pebbles at the substrate. Would it just be better to not put any plants?

Thank you very much for the size info, I'm going to take the size info to my LFS and ask them if they could order me a tank of those dimentions.
 
I have mine housed in an 8' diameter 30" deep pond and I still think that its to small to keep one once they hit the 3' mark I am going to put them into a larger tank that I started along time ago just ran out of funds to finish it since I go out and buy stuff all the time it has been put on the back burner till I can afford to completely finish it... but it is 10'x6'x40"
 
i have my black arow in a 240 but its 5L 3W 2H and i wish it was few feet longer but i think it will be big enough and if he gets really big i will upgrade to atleast a 300 and probally will by that time(wish i could now)
 
I just really want to get one. I love how they swim, how they look, everything. I didnt used to like them a whole lot, but now that I have seen one and actually got to look at it and watch its eating habits (There were about 4 baby jar's eating baby tetras) I'm obsessed.

I was going to get a 125 gallon and try breeding jags and now I cannot decide wether it be a jardini with the tank size mentioned(I dont know how many gallons that really going to be) or just getting a 125 and buy a couple jags and wait until a pair is formed then take the other back to the lfs.

I wish they could both be kept but then I'm sure I'd need a gigantic tank as theyre both fairly agressive.
