I have no idea what filter i should upgrade to for my 150 gallon aquarium. I currently have 3 Oscar fish in it that are relatively 3 years old. They are showing signs of HITH disease in their sensory pits and i know these cheap filters that hang off the back aren't cutting it. I was doing some research on the FX5 filter and noticed something about the FX5 being able to do water changes? I'm currently having to vacuum the tank per 5 gallon bucket. With me currently going through college it makes this a rare occasion due to how time consuming it is, and my terrible procrastination. The main thing I am worried about is how easily it will be to set up the new filter for my tank. I'm not looking to drain the tank nor drill any holes in the tank. Any body have any suggestions?
Also my Oscars have been fighting extremely bad today. Usually they just lock lips but it seems my tiger has become extremely aggressive. To the point that I am scared for the other fish's lives, he is ramming into the Red Oscar's sides and literally just ripping scales off.
I keep interrupting the fights with a fish net and separating them, I just don't have a divider. Any ideas where this sudden aggression may be coming from? I have never seen him act this brutal... Thanks for all your help.
