So amazing as it seems they say you shouldn't put jack dempseys in anything smaller than a 55 gallon am I correct? Well I started my pair in a 10 GALLON....... I currently have them in a 20 gallon and I am now being forced to upgrade due to my surprise of walking in to feed them and seeing at least 200 fry swimming all over the place in the tank..... I am just hoping they don't decide to go near my filter and get sucked in :D anyone want some fish?

    Yeah you use tap water, then the stuff that neutralizes the cornile in the water, just be sure to follow the directions on the bottle. You need to have a filter too. The basic rule for fish is 1 inch of fish per gallon of water, so try not to overfill it. I have a bit over that, I have 10 fish in a 10 gallon tank but one is a algae eater, so he stays out of the way of the others, just stays along the wall. You will need a light and possibly a heater depending on the type of fish you have, they will let you know at the pet store.

I have a 60 gallon tank with one Jack. Do you think it would be too small for three or four even if I arranged a spot for each? If too small, would it be okay to get another male, I'm not too sure how I could deal with so many offspring!

    I a well planned tank it will be fine.  make sure to have over sized filtration.  Upgrading in the future may be needed.

Can I keep 2 or one jack dempsey in a 29 gallon?

    A minimum of a 50 gallon tank is recommended just for one - so even 29 gallons is too small for the adult.
  • Jeremy Roche - 2012-05-09
    These fish get large. 29 gallon is fine when very young for 2 but they will out grow the tank so be prepared to upgrade as they grow.

My jack is very peaceful and scared of my other fish and they are tiny compared to him

    If he was last in that could be the reason. As he gets comfortable he may lash out.

I had a 12 year old jack dempsey called 'the juggernaut'. He passed away Dec 2010. He ate everything we put in the tank, other cichlids, angel fish, hilaries, you name it he ate it. He would only come out to eat if I was feeding him. I miss him, best fish ever.

    I had a Jack Dempsey for at least 5 or 6 years when I lived in Minneapolis. Then I moved home and had him for 2 or 3 years more. Then I had a friend who was wondering if Jacky would like minnows and would eat them. So we put minnows in the tank. I guess I wasn't thinking and he got ick and other problems so sorry to Jacky. I put him at the end of my dads flower garden. He is still there. May he still rest in peace 2003. Thank god

    Sounds like a female golden dempsey

I have a female jack dempsey and a male j.d. I have had them for over a year now. They have paired up but have not laid eggs yet. I feed them pellets and other frozen foods and worms sometimes. They are in a 55 gallon tank. I also put a mirror on the side of the tank but they have not spawned yet. What am I not doing right? I also put a slate in with them can you give me some advice? Thank you.

    The jacks are really shy they need all the privcy they can get. You may need to cover the front of the tank.

    Turning up the heat a few degrees can help.

    I have a pair of Jack dempseys is the second pair I have had, the first many years ago. Both have readily spawned and reared fry. Are you sure you have a male and a female? Second, I always supply cave areas for my J39;s so if they want to hide they can, and usually it is in the provided cave area where they spawn, bringing the fry out to deposit in one of numerous pits they have made. I keep the temp at 78 and ph at 7.0. Filtration is both biological and chemical (charcoal). It sounds as if feed is similar to you, except I add the algae wafers that they sell for plecos. Good luck! JDs are awesome parents and it is fascinating to watch them care for they young.

I recently lost two Tinfoil Barbs in my 55 gallon tank. Now I have my one Jack Dempsey. He's 5 years old and full grown. I would like to add a fish or two. What would be the best fish to add and hope they get along?

    My oscar and 3 jacks do fine as long as you keep plenty of feeders.
