I have 2 jack dempsey 2 kissing fish 2 oscars 2 convicts and some assorted bottom feeders. The oscars, kissing fish, and the dempseys, get along great and so did the convicts until the convicts had babies. That I think is cool, but my point is they all get along fine other then mommy and daddy guarding their young. And I can't blame them, I protect my kids, so it's great that they do.

believe the hype. dempseys are the baddest tropical fish you can easily get. Period. I had one when I was a kid, and he wiped out the whole tank and lived alone for nearly 10 years. Now my brother has a full grown male, about 8", in a 55 gallon tank and this jack also wiped out all of his tank mates. He has tried every fish he could find; oscars, red devils, red terrors, the dreaded green terror, and other assorted cichlids, and "jack" has killed them all within hours of them being placed in his tank. Now this fish is beautiful, amazing coloring, but they seem to be loners. So if you want a tank full of pretty fish, don't get a demsey. (by the way, I just got a 55 gallon tank myself and filled it with 10 tiny, maybe 1", assorted cichlids and, yes, I put a demsey in there. Wish me luck!!)

I have 2 Oscars and a Jack Dempsy. I just got them a few days ago from the pet store and the JD won't stop harassing the Oscars The aggression just seems to get worse every day. I don't know what to do. I'm also afraid I'm over feeding them trying to make him less territorial over food. I don't know if they are males or females either because I let my dad pick them out so I don't know if that is a factor or not. Both Oscars are huddled up in the corner of the tank hiding from Jack. Plus Jack is a little smaller than the Oscars so I really just don't get it. Help please!

    You should get a tank divider, leave it in there for a week or two until the jack learns to ignore the oscars, and after you take the didvider out if it still happens, put it in for another week or two

Okay, I have two JD's and I'm not sure which one is the male or female, or if in fact I have a male and female. It could be I have two of the same sex. But the question is, one of them is getting really fat like it could be full of eggs. Do they get fat when full of eggs? Just wondering if I need to be watching for babies soon. Okay well thanks

Hi everyone, I have two JD's and several convicts along with other cichlids and they have been together for six years now. They do well in this group, I have given them hiding places and the plants they love. My convicts are always having babies, they are very aggressive at protecting them too. I have had tanks since I was five years old and I have to say that I have enjoyed having the cichlids the most.

Hello everyone! Today I've bought an Oscar, a Green Terror, and a Jack Jempsey. They are all tankmates, just the three of them. The Green Terror and Oscar seem to be the best of friends, but the Jack Dempsey is hiding. My guess is it's because they just changed tanks and that they are new to each other.

Today I bought a JD and he's doing great with my other fish. He's shy but will come around later on and he's in the tank with a few Oscars, Convicts and Parrots. All in my 120 tank and all getting along well from what I can see now. My bigger Oscar, Tantrum doesn't mind him and leaves him alone and if anything JD helps find food for my Tantrum which is cool to watch, and they pair off sometimes leaving the younger Oscar, Tyke alone! Pretty cool fish and going well.

`My freind bought me a pair of Dempseys last year and lo and behold they're a breeder pair. They are moving rock from one side to the other of the pit the male has dug. She's changed color completely getting the most awesome orange dots on her dorsal fin. I'm amazed. I've started feeding her worms, he won't eat them. They eat from my hand and have personalities. They rush to the front and top of tank as soon as I walk in the room. They beg. I'm getting ready to move in the next couple of weeks and don't know if I can move the tank or how to move the fish. I don't even know what the eggs look like. Can somebody please tell me what to look for. My male is about 7 inches long the female is about 5 and a half. He's chasing her around alot. I'm wondering if I should move her to a different tank at some point. Any answedrs you guys.

When I bought my JD's I only got them because I always heard about them. I put them in a 50 gal tank with some pleco's and a mixed variation of other cichlids. I bought 2 because I didn't want to just get one. Didn't know anything about JD's. But I noticed from the time I had gotten them that they never split up. Very calm and peacefull fish. They never did any mating rituals or anything like that. And one morning I woke up and they laid over 200 eggs on top and wrapped around a skull that I put inside the tank. I'd say about 50 of the eggs got all fuzzy and nothing came out, but the rest of them were wiggling around and now they are all swimming high and all around the tank freely. Dempsey's are a awesome fish to watch raise their fry. They won;t even eat, they just put everything in a stockpile for their young. The female always tries to come at me when I'm scooping out the youngins but when I put my hand in the tank she lets me touch her. Very awesome feeling. As a first time breeder. I still have about 120 babies swimming around the tank. I feed them baby brine shrimp and crushed flakes. Coors are turning out awesome. Although I must say I was never planning on breeding but now I can't take my eyes off the tank.
