    I really wouldn't sugguest it, but it might work out. I've had my EBJD for about 7yrs. I got him when he was a baby and threw him in a community tank. He got along fine with my bottom feeders (DoaJo loaches/clown loached) pleco.... had him with discuss, angels. I'd think as long as your lobster had somewhere unreachable to hide he might be ok
  • Jeremy Roche - 2012-03-11
    Your Dempsey may end up eating the lobster if it is to small.

JDs are really amazing. Sometimes I think they can understand me! If you're planning on breeding them, be sure to have the space. The male is 5 inches long and the female about 3.5 inches. They spawned twice in a 20 gal. I moved them from the fry when they were a week old. The parents now reside in their own 55 gallon planted tank. (they totally trashed the place!) Three days later they spawned again! 4th time in 2 months( they will eat the fry if disturbed too much DOH! The fry are really unique and some are blueish with vertical tiger stripes. Food is important and some kinds make your JD and most cichlids aggressive. email me at tenthousandgallons@yahoo.com subject:JACK DEMPSEY and I will send pictures. They are for sale and soon I hope to have a website up. Thanks to the economy I have lots of free time to raise the healthiest fish around.

    Hey, I'd like to see some pic's and get a little info on my community tank.

    Do you still have Electric Blue JDs for sale (Apr 2011)? I just lost one that I had for nearly ten years - he was quite large (8-9 inches and well over 1 lb.) and exquisitely beautiful.

    Please send pics and price thank you

    Hello. I want to get into the JDs and was wondering if you had any for sale. The electric blues are hard to find at a reasonable price, so I thought I would help out and increase the supply through breeding and lower the price for newbees to the Jack Dempsey world of BLUE!!!! Can you help?
  • MC - 2012-01-26
    I have been wanting EBJD for a long time! Do you have any for sale?

Just thought I would point out you can't breed straight electric blue jack dempseys. You must use an electric blue jack dempsey with a regular jack dempsey with an electric blue gene.

    OK being a little niave here but how do you know that a jack dempsey has an electric blue gene? What happens if you breed two straight electric blue jack dempseys?
  • Tank Dwellers - 2011-11-10
    Yes I agree. If you do get them to breed EBJD to EBJD they will come out with major deformities and usually die off quickly. I have not experienced this myself but it has been rumored throughout the community.

Hi everyone I just bought 3 EBJD and I'm so excited! I was going to go get different fish today for my 55 gallon but I saw them and had to have them!

So I was wondering if anyone could tell me any information on them preferably very detailed since this is my first time with them and I want them to have a very good life! Also specify any breeding tips!

I plan on getting 3 more in 2 weeks so I will have a total of 6 EBJD in my 55 gallon!

Thanks for anyone who took the time and had the generosity to answer my question!!

    I am curious as to how your six EBJD are doing in a 55 gallon tank. Are they getting along with each other? I just got three babies and hope they can adapt to each other in my 55 gallon tank. They seem fine so far. Its been three weeks. One is slightly bigger than the others and is the donimant fish. They are like dogs is many ways. They are fighting over food and space. His aggression is not brutal at all just a little chase and nudge.
    Let me know how your six get along. I might get a couple more if the 55 gallon could hold more. I am not sure about that.
  • Ed - 2011-05-05
    6 jack dempseys in a 55gal! I'm pretty sure that isn't even big enough for one fully grown jack. I hate to say it but you are just asking for trouble here. Very aggressive and territorial fish. They will beat the hell out of each other when mature without a couple hundred gallons to play with!
  • George Heath - 2011-08-10
    Hi There New EBJD owner! They truely are beautiful fish but if you are purchasing 6 EBJD to breed with each other that will not work. You can only breed an EBJD with a normal color JD to get young that will hatch or survive. Most breeders agree it is better to use an Electric Blue male with a normal color female. The biggest obstacle is that in order to get any blue babies in the 1 st generation, the normal female "must" carry the blue gene, however, all of the babies you produce, will carry the blue gene.
  • Anonymous - 2011-09-11
    No you cannot have 6 in a 55.
  • Tank Dwellers - 2011-11-06
    6 EBJD's in a 55 gallon tank is the equivalent of 25 clowns in a volkswagen. Get a 125 gallon tank or bigger or sell the EBJD's to someone who has a 125 gal or bigger. These fish are not as aggressive as their regular cousins but they can be a bit territorial. I have 13 of these wonderful fish and I keep them in a 90 gallon for 2 or a 125 gallon community. My favorites are kept in my living room in a 240 gal.

I am getting ready to start over with a 100 gallon tank and have some time to research what I want as I wait for the tank to set up. I have had Oscars, Dempseys and Green Terrors for years but I'm looking for a change. I absolutely love the EBJD but I was considering going to more African Cichlids this time and I'm thinking they won't get big enough to hang with a Dempsey. Thoughts? If you had a 100 gallon tank to start anew....what would you do?

    The blue jack dempsey is not nearly as aggressive as the regular jack dempsey. I would not put a ebjd in with africans Africans are more aggressive. I have about 20, 6-7 inch male ebjd in a 125 gallon with community fish (barbs, rainbows)and they get along just fine. I bred my best ebjd male and a reg jd female and now have hundreds of bluegene babies. Very excited! I posted pictures on monsterfishkeepers.com.

    the discus water requierments are very similar and they grow to about 6 inches
  • J Sedillo - 2011-08-24
    I have a 150 gallon tank and two reg. JDs. They are mixed in with various african cichlids and have been fine for seven months. All species have gotten along very well w/ no casulties. Have been debating myself if I want to add an EBJD.
  • noone - 2011-09-15
    I would'nt add a electric blue dempsey to the tank with 2 regular jack dempseys and african cichlids. The reason is the electric blue dempsey is quite a bit less aggressive then the other jack dempseys. And definately a lot less aggressive then the Africans. But if you want to try it, make sure you redecorate the whole tank, plus feed other fish first, and turn the lights off before you release the electric blue dempsey. And one other thing the electric blue dempseys may not like your PH or water hardness if it is not soft water. PH should be no higher then 7.0 or less.

If you are going to attempt to breed the electric blue jd, you might want to read more about the breeding. To get the true electric blue JD, you have to go through an extensive breeding process. Mating two electric blues will not result in electric blue offspring.

    I knew what you said. But I would like to know what you spawn them with and if you need a certain combination or not and what is the number in a clutch and remember by home grown.

My fish is being very antisocial and has not really come out of his home much in the last 4 months. Why and what can I do to make him fun again cause he was pretty cool now I don't like him at all cause he is so boring.

    Some fish enjoy staying hidden and not out in the open all the time. You could try moving his home around from time to time or taking it out completely - but keep in mind he feels safe there. Maybe add some plants that he can "hide" in on occasion as well. You may also want to try to interact with him more during feeding time - when he has to come out to get food.
  • Kim - 2011-04-02
    If your EBJD is still shy. I have read that they are fearful sometimes alone. Is yours alone in the tank? Apparently, they can assume all the other fish got eaten! So get a few other fish semi aggressive type fish so the EBJD can see they happily swimming by.
  • Breakaway - 2011-07-31
    My pair of EBJDs were very shy and hiding all the time, until I put 6 Giant Danios in the 55g tank with them. The Danios are active surface-and-middle swimmers that can get away very fast and won't get caught by the Cichlids. Since then, both of my EBJDs hardly ever hide anymore. The Danios did a great job drawing them out and showing them that there was no real need to be shy. Hope that helps!
  • Chrissy - 2011-08-06
    Assuming your tank is large enough...And he went asocial nearly right away after exploring his new tank (as low interest in food along side hiding can be a sign of illness). And that he's the only occupant (other fish especially in a small tank could scare a timid fish)...you may want to consider adding LOTS of hiding places. The more things they have to hide in, the more likely they are to be more comfortable coming OUT of hiding. ^.^

    Visit the live fish section of Pet Supply to find merchants that sell this fish. You can compare their prices and purchase from the merchant of your choice!

    I'm working on some now. My fry are still too young to be sure but I think I will have 8 electrics out of this batch. They are only 1/4 inch now. Maybe in a month I will be able to tell.
  • Dan - 2010-06-06
    Cichlid Station on EBAY has nice ones. I ordered five two weeks ago to check - beautiful. 3 days ago, I added 10 x 1 1/2" to 2" more EBJD's to a 180 with 30 "community cichlids". For cover, I added black river rocks, soft long grass plants, and additional river rocks in each corner and in the center of the tank should they get outgunned and need to run. I have a aggressive 72 cichlid tank that I find very helpful when adding and sorting new fish that are compatible.

I have 5 Cichlids 2 Jack Dempseys, 1 Firemouth, 1 Convct and 1 Albino. They pick up rocks in their mouths and rearrange the tank constantly. They pile gravel in the front sometimes as high as 6-7 inches. Numerous other little piles throughout the tank against the tank wall. It's driving me crazy. Why are they doing that?

    Cichlids love to dig. Get used to it. When you clean your tank just fix it. Or you could get bigger rocks. I enjoy watching mine dig. My Midas moves pounds of rocks a day.
  • jon - 2010-06-04
    lol they're decorating the way they like it my oscar and firemouth and jd do it they pick up sand mouth by mouth and move it to a spot move plants rocks sea shells to were they like them and think they look good just the type fish they are.
  • Dan - 2010-06-06
    I believe they are building fish "homes" or breeding areas. I don't disturb it unless I'm vacuuming the gravel.

I have 2 Electric Blue Jack Dempseys. They are each about 2" big. I now have them separated in a "holding" tank because I have a 75 gallon community tank with 4" Jack Dempseys some other 4" cichlids and some other aggressive 3" cichlids. Do you think it is alright to introduce them into the 75 gallon community tank now because they are miserable in the 10 gallon "holding" tank, and I don't think they're eating that much at all. What is your opinion? Thanks, Jim

    Try it. Make sure you're going to be around for a day or so. Keep a close eye on them and see what happens. Don't feed anything like live or frozen food for about 48 hours. It makes them aggressive to new fish. If they do beat the crap out of each other, I found that a separate tank with MELAFIX works at healing wounds and bruises in 3 days..
  • eve - 2010-05-31
    I had to pull mine out of my 125 ( 6" Black Belt, 4" and 5" Geo's, 6" Clown Loaches). They were all babies together, but he stayed small and the rest grew. He was so scared of the bigger fish, he started hanging out at the top of the tank and not eating his dinner. I put him in my 29gal planted blackwater tank (1 med Angel, 18 neons, 6 micro-cories). He is so happy, he is eating, swimming just for fun and chasing the neons.
