Have an 8ft tank 360 gallon
Decided to grow out fish and choose my favorite when grown
Currently have 3 datnoids 5 inches
And 2 Oscar’s, green terror, red vieja, all about 4 inches or less.
Black arowana 14 inches

the vieja which I just added is the only problem constantly chasing other fish, but never hurting them. Should I remove this fish?

also should I try adding more smaller cichlids to the mix? In the end I will choose the best behaved ones and sell the rest, just didn’t know how people made successful monster community tanks

:help2:

Not an expert but the Veija might be just claiming territory, would add more decor and watch closely

Have you got any hiding places, driftwood or anything? The dats may not like to be out in the open being chased around.
 
I find most Vieja can be quite aggressive, and I have kept 6 of the 8 species in the genus, and a couple that were formerly in the genus such as both Maskaheros.
Central American species are too territorially aggressive to be kept with S American, or Asian convergent, or even non-convergent species.
They are generally much more aggressive than Dats and Oscars, so I don't believe Vieja should be kept in the same tanks with them, even if the tank is large..
