ok we got a 4 onch jack for our oscar will they get along maybe has anyone had one with an oscar or any expierence with them any help would be great are they good fish or interesting

i've heard of lots of people having jacks in with oscars and how they make great tankmates. but i have tried this combo with my jack and have had no luck at all with it. the only thing my jack hasnt attacked is a female dempsey i got for him. however they are both living happily in the new 65 tank i had to buy for him.

ok thankyou very much i think its a beautiful fish i hope it works out i dont wana have to give it up or get a new tank

I have 2 jacks and 2 O's with 1 Pictus Catfish.

1 The Bigger Jack picks on the smaller Jack (bought at the same time and size) and the Bigger Jack will hang with the O's.

But the Pictus Catfish is the enforcer/boss, he chases the Bigger Jack and 2 O's if they're picking on the smaller Jack... It's kinda weird seeing that.

I have an 2 Oscars an a Jack Dempsey. The JD is only 3", and the two Oscars are 5" and 8". I added them all to the tank at the same time so none of them had predetermined territories in the tank. They are also in a 125g long tank, so they have plenty of room.
