I have a 210 Gal with around 4/ 8-9" Oscars, a 24" high fin pleco, a 10" high fin pleco, 2/ 8-10" Limas', an 8' Peacock Bass as well as a 9" Black Wolf Fish. The last fish I want to add to this tank is an Arowana, around 9". I do not have issues with aggressive behavior, besides the occasional nip or rub against each other. The Bass is an aggressive eater but otherwise stays to himself and when around others is the sweetest. The Wolf, he swims around with the other fish and I have not seen too much aggression from him. The Oscars will be Oscars and from time to time open mouth fight with each other when feeding but with no bodily damage.

I have minimal ornaments in the tank, 1 large centerpiece of Manzanita wood and 1 Mopani wood for the giant Pleco with fine gravel. I don't know if any of this matters, just trying to give as much info as possible.

I read online that the Bass and Arowana may butt heads but if fed separately that will minimize aggression and keep the peace. I look to you, my fellow monster keepers, to ask for your input. Does anyone have any advice? Thank you, kindly, for your comments in advance.

I would pass on the arowana. They get far too big for a 210 when full grown. Beyond that, even if the current stock works now, those fish aren’t close to done growing.

Agreed. if you manage to get a larger tank then you can add the arowana. there won't be any issues. the small aggression problems you are facing right now will also end.

That bass seems like a sweetie because it's a baby. Somewhere around the 10-14" mark you're likely to see a behavior shift and an example of bad behavior I had (and still have) an adult flag tail that was in the same tank w/ three peacock bass. The flag tail would occasionally chase the bass around but flag tails present a nuisance to others in the tank but normally aren't particularly aggressive.

I walked into the tank room one morning and three peacocks had the flag tail in a corner and were taking a solid crack at killing it. It took a couple three months to nurse that flag back to health and get it's fins back to right.

It's also important to know what kind of pbass you have. A Temensis won't fit in your 210 as an adult and would likely be capable of inhaling all but the largest of aros. Any idea what kind of pbass you have? A Kelberi might be ok.

I honestly don't understand why so many pair pbass w/ arowana (as have I). The nature of the arowana is entirely different from the pbass and if they're around the same size the aro is definitely a potential food source.

Your tank is already pretty well stocked, an Arowana wouldn't fit. Maybe you could get another catfish, MAYBE...but with the wolfish I highly doubt it.

I hate to be that guy but… you are already substantially overstocked

Pbass or any type of bass can kept with tankmates like Oscars red devil's etc, including large fishes like arowana rtcs clown knife fishes, etc. The trick is to provide them with a large enough space and provide more than one tank mates to spread aggression. In your case, the pbasses were aggressive because the only fish they could bully was the flagtail, inappropriate space,etc. Otherwise pbass rarely bully large tankmates like RTCS arowana clown knife fish etc. They rarely bully Oscars and other similar sized fish. This fact can be proved by numerous YouTube channels like ohi fish rescue, Paul cuffaro etc. Moreover I am definitely sure that there are a lot of members on this website who have tried out community tanks with pbasses.

I wouldn’t use Paul Cufaro as an example lol
