jackdadempsey · 05-08-2005, 06:52 PM

I think it's a gamble you will just have to watch carefully. I have 2 jack dempseys and 2 albino oscars in a 100 gal. tank, and they all get along pretty well. There is always the possibility for personality problems that you will just have to keep your eye on.

I'm thinking about setting up a similar agressive tank. So what other agressive fish would do well in a tank with Jack Dempseys and Oscars?

With the Jacks and OScars both about the same size, you shouldn't have any problems, unless you got the occassional bully fish (some fish, no matter what you do, will try and fight anything else in the tank). I had a jack, 2 oscars and a shovelnose catfish together and they lived very long, happy lives. Most semi-agressives and aggressives do alright with each other as long as one cannot fit into another's mouth.

Unfortunately that tank isn't big enough for those 5 fish in the long term, You WILL experiance a lot of waste, fighting, etc if you do not upgrade... Remember these fish grow 12 inches, and adults get more an more aggressive as the age.

Sorry, I meant you shouldn't have any problems, assuming you upgrade, of course. fishfirst is right, the waste alone would be reason enough for a bigger tank before adding anything.

I suggest that if you want to keep the oscar and jD till there adult lifes then you should buy a bigger tank, otherwise fights will break out very frequently.

I wouldnt actually be VERY cautious about mixing them. a friend of mine had a lovely oscar, with a suckermouth Plec in a 75Gal. He introduced a Jack Dempsey, the Oscar kept trying to Attack the JD, but the JD was too strong Oscar lost an eye, Eventaully over a few months it got more and more beat up, got head rot then died, poor little bugger. You might be Ok as the JDs are already in there and have a territory. Like Cichlid man said bigger tank!

Or take him back and get a Convict Cichlid as well, my mate got one and it takes no nonsense from the JD, its too fast. Actually they hang about together now after a bit of aggression from the JD.

I keep a successful community of fish in a 4 foot tank including the following families: Cichlids, tetras, loaches, gouramis, barbs, rainbows, livebearers, killiefish, catfish, puffers.
