I will be starting to build my outdoor tank in a couple of weeks for my arowanas.
Right now I have two silvers, one black, one RTG and one jardini arowana.
Would an 8' by 3' be a good enough tank size for them or should I go bigger? This tank would be to house them for life, Plus, Would I be able to add more fish into it? possibly another asian arowana?

I do know the chances of having a succesful community tank are slim btw, but as of now I have the RTG, black and one silver all of whom are around 13" to 14" in one tank and the other silver of around 26" and the jardini 16" in a separate tank... I hope to introduce the three smaller arowanas into the tank I will build once they grow a bit bigger..
thanks in advance!

You might have problem with the Jardini if you try to put them together. Not really a very sociable fish. 8 X 3 will be abit tight if you hope to house them for life. 10 X 4 should be more appropriate.
 
I've tried adding the Jardini with the three small arows and had to take him out due to aggression but I think I'll give it another try when my RTG is bigger because he seems to be more aggressive than the Jar.
Thanks for the advice!
 
Solomon is right about the tank size, and also about the jar- youre not going to teach an adult jardini to be social- you gave it a shot, you got the usual mean jar, and you probably knew he would be mean when you got him- so to "give it another try" is a mistake- youre RTG being meaner wont keep the jar in check, it will have them fight to the death, and it will really bite when the $50 jar kills the $1000 RTG, and everybody says I told you so- good luck
 
we are always hoping that a miracle will happen when a Jardini can live in peace with other arowana tankmates in a community tank. What are the odds? Only when disaster strikes then we learn ... the painful way. Just like hoping a few male Siamese bettas would live in peace together in a tank.

na, but the jar has lived with other fish and still does.. either way, i'll see how it goes..If it doesn't work i'll just sell the jar and get something else. The jar isn't my biggest problem.. Its the silver, he is by far the meanest but I'll grow out the RTG and the rest first and see how it goes..
The tank size seems to be my biggest problem as of now.
thanks :)
 
Depend on you really. Always bigger is better. I have 12 aros in a 7x3x3 at mo. No problem!!! But I will upgrade to 12x4x3 next year tho.
 
Currently I have a 8'x3'x30" tank stocked with two 28" silvers and two black aros at 25" & 16". They do now have room to move about, but I would suggest a bigger tank as I believe eventually all these fish will be 30"+ and the tank will become too small.
 
Agreed, I have 4 silvers (all still small, at about 12-15") in a 8x2x2...only have a few other smaller fishes in with them atm and they're okay. However, if I were to set out to build a 'lifetime' tank for them, it would be no smaller than 10x3x3.

Also, a river-tank style setup where you have a strong current moving from one end to the other goes a long way in simulating the supposed "endless tank" and keeps them exercised. Just make sure there are at least some pockets where the water slows down and they can rest.
