I am going to put a 1 1/2 long Jack Dempsey with a 2 inch Oscar in a 55 gallon tank. Niether of these fish have been in the tank yet. I have called 3 different stores and been told 3 different things about puting these fish together. One place told me that no matter what size the dempsey was he would kill the oscar. Another told me the oscar would kill the other. The first store told me that since they are going into the tank at the same time they would be fine together for years. Help please!

I had a Jack Demspey and Oscar together for years in a 55 gallon and never had a problem. They were both about the same size as yours when I got them (at the same time) and they both claimed a section of the tank for themselves and never seriously challenged one another. I would say it is worth the risk.

I would agree with the pet store that said they would be ok together because they are both young and will grow up together. I have had experience putting jack dempseys together with black belts, which are also supposed to be very aggressive, both when they were young, and never had a problem. I say go for it.

With cichlids its a touch and go kind of thing. Each fish can be soo differnt in perosnality you never know what will happen without trying it. I recomend having two females though. You will have much better success that way then trying to house males together. And if the fish you have dont get along try relacing one of them and that might help. Lots of rock work and places to hide at first, incase there is a dispute. As they get bigger i would have less and less decorations due to there wanting to re-arange the tank.

I have always had good luck with both of these fish, I agree with the fish store that says they'll be alright.
Starting them out together when they are that size greatly increases a good out come,but just keep an eye on them at first, you may have to swap one for another due to personality.

I currently have a male JD in with a female convict, they have been together for 5 months now with no problems.I also have serpae tetras and bosemani rainbows in the tank with them as target fish. I find it a good combination and a pleasantly active tank.

Jack dempseys and oscars can get along, but a 55 gallon will not be big enough to hold them for life. you'll be ok for a year or so, but then you'll need to upgrade to a larger tank if you plan to keep both of these fish together for life.

I would agree with eventually splitting them up. Eventually the Oscar just got too big and I moved him to a larger tank.

The 55 would be fine for the JD and i am a firm believer that a single oscar can be kept in a 55 but not both. JDs aggressivly wise are over rated unless you have a wild specimen. My JD is first generation wild and goes around locking jaws with every fish in my tank he even has a go at my synspilum that is at least 2x his size. Wild specimen are more aggressive than commercial ones because in the wild they are loners kind of like male lions allways fighting and the older and more fights they have the more scar tissue they develope on there top and bottom lips making them a force to be recond with. I think a full grown jd would kill a full grow oscar but if you grow them up together they should be fine.

I have had these two fish in the same tank and they did fine together. Every once and awhile the JD would nip at the oscar but nothing serious.

Bostonjon, you actually already have that in this post, but a question I have is aren't they a bit small for 2 and a half year olds?
