Bocourti and Oscar in a 125 gallon.

  • We are currently upgrading MFK. thanks! -neo
You do you, but if you really want tankmates in a 125 theres better choices that still get a good size. Maybe the bocourti could have some tankmates, not sure, not too familiar with item. Chocolates, severums, geophagus, etc can all live together.
 
I have a 6'125 with a 12in male Midas and a 10in female Festae i do 3 80% WC a week (Mon,Wed,Fri) and trust me if your not up to that for the next 10-15 years then you need to listen to everyone here. in the last 6 months i've been measuring spaces to see where i can put a 180 just the 2 fish i have seem to big for a 125

That thread talks about good Oscar tank mates. For the tank size you have.
 
The group of peaceful tankmates doesn’t have to be huge. Their adult size just has to be too big for a 13 inch Oscar to eat.
Hate to tell ya, O's get bigger than that. Mine was a hair over 15 and still growing. Others here have had 14 inchers. They can max at 18 but are usually old in gigantic public aquariums.
For a 125 you could try

1 O and two parrots

or 1 O, one parrot and one acara

+ A few danios if you want fast smaller fish to mingle (likely snacks but some might escape or be left alone)
