I added a Jack Dempsey into my tank and one of the Oscars chases him around and bites at him. Any way I can stop this?
 
move around the items in your tank, like rocks and structures because it sounds like the oscar has taken the tank and made it, its territory. that usually helps with the problem
 
Defiantly not removing the Dempsey because it's not at that level yet. Should I move a majority of the decor or just one part of it?
 
Move everything around.

Give the Jack a chance to develop realty at the same time as the Oscar or else there will be property disputes. Oscars are terrible neighbors.

A petco associate once told me to put the most aggressive fish in the tank last, such as adding the jack and then keeping the oscar in a different tank for a day or two, he of course was referring to things like, put the Tetras in first then add the Red Devil. The man was a genious. My version should work better than his, no promises however.
 
What size tank do you have them in?
 
I would do a massive water change when you move stuff around....

That renders the tank totally different for a spell, and when the water comes back up... taa daa its like a new tank!


How big a tank is this? Is there enough room for them both?
 
After moving the decor doesn't work I will remove the dominant one for about a week then reintroduce later. Once you remove the weekest one it will almost never gain a spot in the pecking order. By removing the dominant one you give the weekest time to settle and adjust. Also you can try a divider for awhile until the JD settles.
 
I always add feeders when i put new fish into my oscars tank it keeps everyone busy and the new guys get a chance to adjust, i just finished incorperating a GT into my O tank he was added with 20 rosey barbs all went very well.
2 oscars1blue acara 1 salmon cat,2 plecs , 1gold severum,2 geophagus red heads, 1 striped raphael cat , and now 1 Gt. have 2 left over rosey barbs lol.
 
Alright, I moved everything around and I will do a water change today and if that doesn't work I have a tank to move the bully too.
