This is my Jack Dempsey. His name is "Jack". He has gotten larger and has more blue green color than any JD I have seen in person or owned before. Jack lives with 2 Short Bodied Convicts and a Pleco in a 55 gallon.

I love that fish man.... respect.

I thought I posted this last night but I cant find it.
I believe the JD was named after the pugnacious pugilist (boxer) for his hard none stop fighting technique, running around the ring harrassing his opponent. I've been told these guys are very similiar in the tank...... lol

Thanks again Jamie!

Yeah, I had posted a pic on a different thread in regards to hand feeding and teeth on fish. You may have replied there too.

Your correct on the naming of the JD. And they can be quite the territorial guy in the tank. I actually got this one from my brother when he moved and didn't want to take the tank about 9 months ago. I had another JD at the time that was smaller and less bright colors, so I thought mine was a female and this one a male. Tried to keep them together in attempts of breeding, but "Jack" wanted nothing to do with the other JD. He terrorized it for a couple of hours until the other JD threw up the surrender flag in the top corner of the tank. So I decided to give up my JD that I had(taking it to the LFS), and keeping the much better specimen of a JD. He has just gotten bigger since I got him, my brother visits and can't believe how big he is. "Jack" the JD used to live with a large 13" Albino Oscar when my brother had him and the JD wasn't very aggressive then. Not anymore. He allows the 2 short bodied convicts to be in his tank, but they have to stay out of his way.

i've always really wanyed a JD but just dont really have the tank space but i have a few smaller tank mates such as clown loaches and bristlenose catfish and even thought my black ghost knife is pretty big now (around 9 inches and still growing) i dont think he would stand a chance if a JD wanted to start on him......

I always wanted to keep a Jack dempsey but sadly in India we dont get this .. I had checked all the LFSs around... .. but your fish looks simply awesomee..

btw.. has anyone kept jack dempsey with Oscars?? i heard they dont mix.. jack dempsey is too aggressive for the Os ??

yeap i would like a JD too )))) Nice fish by the way.

i have kept a pair of jacks with my oscars for a while. they got along alright but due to space restrictions i had to put them into another tank with my gt and sev.

Does a JD get on normally with a fish like an Oscar, or is that a one off?
