What is your water change routine?
When was the last time you tested your water parameters?
Have you noticed any aggression from the Oscar or the FlowerHorn?
Answer these questions as it’ll help to guide advice.
I usually change 20% of water monthly coz iam ruining a sump on my tank as for my water parameters I have 0 ammonia and my ph around 6.8 and I already remove the Oscar coz it was not getting along with the flowerhorn but I never noticed any aggression on my aro
And since the issue I already done a 70% water change and iam doing a 20% today is that should help ?
I suggest doing a minimum 50% or more water change weekly. You must stay consistent with the water changes or you will do more harm than good. Drastic PH fluctuations will be dangerous to your fish. 20% monthly is not good at all even with a sump especially with Large and messy eaters like Oscar's.
