Ok,

thinking of comming aros. say... 8 to 10 aros (no jardiniis)

here are my thoughts.

im thinkking, if the tank is big, then the aros will try to establish territory
if the tank is smaller, then the aros dont bother and get smothered by each other.

what do you think works?

I mean if i can put a jardinii in there, i would love to
but say

2 black, 2 silver, 2 green, 1x rtg, 1x crosback, 2x red.....

just as an example.
i am thinking, should i do a:

240cm x 120cm deep x 80 high
OR
300cm x 120cm x 80 high
OR
300cm x 120 cm x 100 high
OR
240cm x 120cm x 100high

THinking height may play a part in the heirarchy in the tank. but length means they can escape.

some said overseas that tank size when comming is better smaller unless you have a HUGE pond, cos the aros are STUCK TOGETHER in a tank and learn that there is no point of fighting.

Any opinions?
 
honestly 10 aro in a tank is the WORSE thing you can do with 10 why not do a pond?
 
you have 10 3ft fish in a 10ft tank -.-
 
getting them young is one way to do it. the other is crowding but yeah you want a good filter. i dont know that a bigger tank is worse than a small tank aggression wize if its got ten fish in there. but some have said a shallower tank helps the fish handle it. i guess the theory is along the lines of the fish going through a dry season and say being held up in numbers in a shallow lagoon type thing. and they cant all be aggressive in that kind of situation or they would have died out from killing each other. you can also crowd up with cheaper fish to achieve a community tank. plenty of tanks have fewer than say 8 arows because they have other fish in there too. then there is also the story of using a lot of weed or plants logs etc.. In malaysia you can see plenty of comm tanks with bigger arows and i am pretty sure they arent all kept from small. they heavily crowd and they also tend to have the water jetting into the tank after being filtered..hope this helps. oh yes and maybe you can find a jardini that is not so aggressive. sometimes you can find large ones that have been kept in community tanks with other species and to me, those ones either have the non agressive gene or its combined with the techniques above. even if by chance.
 
I have four South American Arowana in a 96" x 36" x30" tank. No aggression issues. IMO though the tank is crowded, and adding another couple feet in length and depth would not allow for another 6 arowana.

You don't need to keep them all from young. As all four of mine were added together after they were at least 16" in length.
 
mmm interestng, thanks for the feedback! and wish for more feedback of there are more please the more the merrier!

i was told things like jets, bubbles, plants and line of sight breakers help, but yes, agreed, teh over crowding technique is used because as one is about to get angry and attack, another will distract it from doing so, and the cycle continues, just like cichlids in a tank, 2 will kill one another but 5 wont.

filtration is not a problem, never a problem, all the logistics wont be an issue, its the size of tank and stocking thats im worried about.
filtration has never been and never will be an issue for me:D i over filter HARD!
