I currently have a 55 gal. but am soon to get a 175 gal. I have a 3 in. texas cichlid, and 3 2-4 in. tinfoil barbs, and am interested in getting a JD once my large tank arrives. Any suggestions on how to make it a success or warnings? Or perhaps any other tank mates that would be compatible? Thanks.

    I have a large JD in my tank with a parrot cichlid, a tiger oscar, and a large lima catfish they all get along quite well.

    Try rearranging the decor. Sometimes this will help defer aggression for a while.

I've just bought a jd, 3 angels, and 3 convicts. The angels and convicts are best friends but the jd is the most aggressive. He killed 1 of my convicts and all my angels. Every fish I get, he kills it... my red devil; green terror; texas cichlid and my oscar, can anyone help me.

    Put a small mirror at one end of the tank, to keep him busy fighting himself.

They killed my gold severum. Now I have another jd a bit bigger then my texas. They lip locked twice but now my texas chases it and it won't fight back. I heard it will fight back after awhile. The original jd is doing great, he likes ham and turkey =D

Hey, I got a gold severum in with my jd and texas now. I fed them a few live feeders and my texas ate all 3 of the feeders in 2 hours, lol.

Hi, Ii got a new gold severum. Now it is the same size as my texas, but it is a wimp. It's afraid of the texas and strangely the 1 inch dempsey, lol. My dempsey won't allow any fish to take over his treasure chest hiding spot. He shoved my gold severum outta the way, then bit it. So far my texas has tried liplocking with both. I think it is entertaining to see. I think the gold severum is a waste of 14$, but my parents say it brightens up the tank with its yellow. My texas is starting to get these turquoise shiny speckles and my dempsey is getting these glittery dots on his sides. I find them rather pretty fish, they are a fish to be proud of. All hail jack dempseys, =D

Hi, I have a 1 inch dempsey with a 2 inch texas cichlid in a 20 gallon. I plan on getting at least a 50 gallon when they are a bit bigger and a few more hiding places. I love my fish, I've heard dempseys can be rather playful.

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
