Jack Dempseys are beautiful fish. I had a pair of them for five years, the female just recently passed away. They bred 3 times, allowing us to see the progress of the babies from the very beginning. It was a wonderful experience, and I'm glad I got a chance to see it.

I had a pair of Dempseys who, when together laid eggs but unsuccesfully hatched. A short time later the pair has broken up, it has been almost a year now and they are no longer together, though they do remain in the same tank.

I started with 3 Jack Dempseys - 1 male and 2 females. They soon paired up and I had 1 single female. Then I bought a male for her but he was beaten up by my first male. I love my Jack Dempseys, whenever I sit close to the glass he always comes like he wants to talk with me.

I have a Jack Dempsey, it's one of the most beautiful fish I have ever seen. It is very agressive and will kill just about anything in my tank. If youre going to put another fish in the tank I suggest you make it a type of Danio. I would also suggest you buy plastic plants instead of real ones, because he is always digging them up and moving them all around. I feed my Jack Dempsey pellets and flakes but every weekend I put a dozen Rosies in the tank for a little treat. So by far the Jack Dempsey is the best fish around to me.

My Jack Dempsey is still very young, about five weeks, and he has already tripled his 3 cm starting size. I feel that he is a male because his whole gill plate is loaded with metallic spots, not just the top half. He has been through a rough water change, pop eye, which he didn't totally recover from, but after a new filtration idea my water cleared up. Jacks are awesome fish!

I have a single Jack Dempsey who is the ruler of a 170 L tank. This guy is full of character, and he apparently does NOT like tank mates, as is evident from missing fish from the tank the following day. Jacks, when young, are a bit lackluster in appearance, but bloom gorgeous shades of various colors as they get older. My Jack has a striking metallic blue striping to him. It is also interesting to see their mood swings through the different color changes that they go through. Feeding time is especially entertaining. My Jack knows when it is feeding time whenever I tap the glass of the aquarium with a can of flake food. He immediately swims up to the glass and goes into a crazed frenzy until I drop the food in the tank. All in all, this is a great fish that anyone would love.
