Hi, I have a recently set up 75 gallon with 2 medium/ small JD's in it. I also have a 40 gal. with 3 female convict cichlids init. I'm wondering if I would be able to add the convicts to the 75 gallon tank without much problem. Or would the tank be maxed out from the 2 JD's. Finally, if I don't mix the convicts and JD's what else could I put in the tanks for variety?

Brad,

A 55 Gallon aquarium is the bare minimum for a single adult Jack Dempsey. It is possible to house a pair in the 75 Gallon but please be aware, these fish can be extremely aggressive when they are put under duress and will certainly show it. I would add nothing more to the aquarium than the pair of JD's. You would be able to house a single adult JD + the convicts if you did not pair the JD, however.

You should realize that both mentioned fish are highly territorial and if not given ample room to establish their own territory, chaos will erupt in the aquarium. 75 Gallons for a pair of adult JD's would be "on the edge" in regards to territory as they can grow up to 10", they are extremely large, territorial, and aggressive. Jack Dempseys did not acquire their name from being cuddly toys, they rightfully earned it. The same rule applies to convicts.

Both are amazing fish to have though!

Good luck.

Well the convicts will eventually become food, considering the fact that female convicts do not usually get larger than 4.75 inches. You are good for a while tho. Adding the convicts will definitely max it out.

Thanks for the replies. I'm kind of thinking about rehousing one of the JDs so I can have more variety in the tank. Not sure what though. Suggestions?

A green terror LOL maybe a few other acaras like port acaras and blue acaras. A jag would probably work. Senegal bichirs are also a great fish. Sex your your jd that you plan to keep in the 75, males have more like dots of blue on their gill covers whereas females have blobs of blue on their gill covers, unless it is a small enough fish to safely vent, then just vent the fish and get back to me. Make sure you have either 2 females or a male and a female because if you put 2 males in the same tank they will fight to the death usually. Also firemouth cichlids are a great companion for jds, as well as jewels.
Hope this helps

What about the stress on the fish that incompatibility causes? Common sense tells me not to mix Africans and South American cichlids.
I have kept jewels with jack dempsey and even doviis. That rule applies to almost every other African but jewels are ok.
