MIXING American Cichlids with African Cichlids?

It can be done but listen up please, IT'S NOT ADVISED TO DO SO!!!

I can't say that enough. It's not just about the water differences as it is pretty big in difference but tempers and how they interact. South Americans tend to physically rough fish up by using their size. Africans are more of a harassing type that takes picks and bites and is a constant harassment. For the most part, a much larger South American is likely to deal a death blow to an African if it stayed out in the open to fight. Most Africans probably would have enough common sense to try to avoid a much larger SA like your Dempsey, but why even put them togeather in the first place? To serve your own needs? What about the fish?

You're already close to as maxed out as you can get in your 75 gallon tank with those 2 Dempsey's alone. As it is, I hope for your sake, that's a male and female pair. I've seen you ask about stores in your area before and you asked about white spots on your fish. Seems to me, you already have your hands full with that tank, so unless you are going to keep any Africans in a seperate tank, I say again, THIS IS NOT ADVISABLE.

Yeah I know you can see most anything you want on YouTube. I've entertained myself on there as well many times. That's about all I take it for, entertainment. I'd have to say showing that it can be done is one thing, but in doing so, there's numerous view points to take into consideration as I mentioned and it's not just an easy thing to do. Forgive me though as I can't seem to make out your English very well but is this crib meaning Kribensis perhaps? That is an African. They can do ok in South American type waters, but I think they are going to get extremely stressed out by the presence of those Dempsey's and should your kirbs be a male and female pair along with your Dempsey's being male female, one of those two species, come breeding time, is going to lose out and I'd bet big money, it's going to be those poor Kribs.

Just because its on youtube doesnt mean its right. For the most part, Africans are a bit too rowdy for the Americans. Sometimes, you can get a good combination though, but most Americans get alot larger than the Africans, so that would become a problem. Besides, the fout foot tank you have is most likely just big enough for the dempseys. Its probably 65-90 gallons. If you have a pair of dempseys, Im not sure why you are trying to add things, they will just be killed...

it is advised not to do so because of aggression and african cichlids need different water requirements. it also depends on what kind of african and central american cichlids you are talking about. i have mixed a convict cichlid with a kenyi african cichlid and the kenyi cichlid constantly bullied the convict cichlid. really you never know with cichlids they are unpredictable. good luck

Its possible, as long as the species can live in the same water parameters, and would be compatible in the sense of size (ie. American doesnt get big enough to eat the African) Ive never done it but I know african species need a higher ph, especially species from lake Tanganikya. No, you dont need to add salt, they're not brackish or saltwater fish.

I wouldn't, they already tried that in the 60's.
