Hey guys just got my 55gallon for my fish and right now my 7"arowana and 6" oscar are living in it. can I add my 4" jack dempsey with them? I really doubt that they can fit him in there mouth but Id hate to see him get tore up. Thanks guys.

welcome back uselessmidget! its been a while....
to be honest... NO, you can not. 55 gal is good
for one full grown oscar while arowana needs around
125 gal size. once these two reach their maturity,
you will be in trouble, aro could jump out of the tank,
while oscar will establish territorial dominance. when
time comes, you will have a lot of trouble.

just my two cent opinion.

ok i wasnt asking that i asked will either of these fish attack the jack

sorry, perhaps i missed that point....
jd and oscar, sometimes get well together,
sometimes not. as for arowana, i have no idea and
experience about the combination. i used to have
arowana in solitary.

whoa, no need to get pissy. what do you have planned for the aro? i hope something at least 200 gal.

and an oscar and jack in a 55g will not work, IMO. in a bigger tank, yes. I had that combination in a 75g not to long ago.

not in a 55!!!!!!the arro sounds nice tho.......

any pics for us please uselessmidget??????????

I would be very concerned for the Dempsey.. Go to a bigger tank in my opinion.
