Welcome to the community

Don't worry the behaviour you o's are showing is quite normal. You never know, you might have a breeding pair, time will tell.

How big is your tank? O do require large aquariums to keep up with the amount of waste they produce. You should also have excellent filtration since since you have got two large adult Oscars.

Anyway, most photographs when you can, would love to see them

Glad to here this is normal, Thanks..
My tank is 450litres with two fluval 303 canister filters lookin to upgrade this soon tho.. will put some photos on soon..

looks like you done your home work.)))glad to see they are not in a 30g)))

welcome to the forum. just keep an eye if the
twisted tail fin is caused by bullying.
