owww I see. Lastly, if I change 20% of water weekly, do I need to remove my flowerhorn kn the tank or no need?Bubbles are good don't worry about it. You need that oxygenation and water movement.
thank you! one more thing, if I added water conditioner to the water and mu flower horn attempt to drink it, does it harm mu flowerhorn?No you usually should not have to remove your flowerhorn from the tank. I would never do so unless I really had to avoid stressing out the flowerhorn. You should change anywhere from 20-50% percent of water a week Depends on the bioload for your tank size. You could also split it up into 2-3 smaller water changes a week.
thanks a lotProbably not but try and pour the conditioner as far away from the flowerhorn as possible just to be safe.
