HELP REDUCE ANGRY FISH!!

[SaFyQ448]

Ok so my 2 electric blue acaras are fighting in their 37 gallon tank. I feel super bad about leaving them with a fish sitter for a week. Is there anything I can do in the mean time to reduce stress and aggressive behavior before I go? There's 4 Cory's 3 bristlenose and 2 electric blues. I'm well aware it's overstocked and electric blues need more space. I didnt know that when the person sold me the tank along with all the fish.
I have a buyer ready to pick up the fish when I get back but his tank won't be cycled until before. I really could use some help on reducing stress.
I attached a pic below of my setup. And i just added the bucket as like more habitat space?

All of the temp hardness ph is all in the electric blues favor too.

Probably not much you can really do other than separating the fish. Acara are by nature territorial and aggressive.

Your set up is complex, and you couldn't add more. If the 23 fish could coexist, they would in such a set up. But likely, the luck of the draw has given you 2 males. Even mid sized cichlids have a way of making a person have more than one tank. They are not good fish to start with, and there are no solutions other than finding them a new home asap...

No more words needed... Too small to house two of them. Do you have an extra tank or something that could work as a tank? Just to separate those two...

I wish I did. I thought since the previous owners had all those fish together it would be ok. I was definitely wrong. I sold the oscar fish that was also in the tank before and am currently trying to remove the electric blues so I can just have peaceful fish that get along without an issue...

What about two separate buckets? They'll be fine in there for a short while. But be sure that they'll have enough space to move around.
