is it probable that an oscar, jaguar,and flowerhorn can live together?

[djsaltynuts]

i have a small flowerhorn that i originally had in a cichlid community tank but then he started to kill off fish so i moved him. i have a significantly bigger oscar that the flowerhorn kept his distance from. i was thinking about getting a very large tank and getting a jaguar cichlid moving the oscar and flowerhorn into the same tank and possibly another large cichlid to balance aggressive (im thinking vieja, trimac or red devil). if i did this what would happen? i would introduce the jag as the smallest ofc.

I wouldn’t personally do this.
1. The Oscar is a species from South America and prefers neutral to slightly acidic water ph (yes I know it has been heavily domesticated) and it is generally less aggressive then the other species mentioned.
2. The jaguar, red devil and Trimac are top predators in their biomes and are considerably more aggressive then some of the species you have listed. Plus mixing the two amphilophus species being similar shaped you will experience more aggression. That mixed with the fact you want a flowerhorn as well which is another similar shaped fish.
3. I personally would not mix the Trimac with the other Amphilophus and flowerhorn. The Trimac is a species that is and has for a long time been at risk of becoming more lost to the hobby because of hybrids and the flowerhorn craze. I personally keep Trimacs with their own species, or other species found in their biome they are not able to interbreed with.

At the end of the day each individual fish is different and have their own temperaments. It may work out for you, it may not or it may work then one day/ night of the fish in there may snap and kill the rest (common occurrence for some of the species you have listed ). If you plan to go ahead, I would have at the very least other tanks to move fish too/ a place to rehome them if it doesn’t work out

Agree with the above, with the caveat that in the end it all depends on tank size.
What a human considers a large tank, and what territorial adult cichlids deem as sufficient footprint may be two different things.
I believe a majority of humans think an @ 180 gal tank is large
Your cichlids may consider a 350 gal minimal to not create constant turf wars, 500 gal or more even better.
So my guess is in a 350 gal, you have a chance of it working, any smaller, I doubt it.

I agree with Duanes. Above a 300 gallon you have a chance, if you aren't worried about the pH, etc. Below that, it's almost certain to fail.
