I currently have 2 oscars one is 5'' and the other is 7'' in a 150g tank. I also have 2 plecos one is 7'' and the other is 14''. The thing is I was told that I could get away with 4 oscars in my 150g. If I do wouldnt I have to get rid of the plecos or could I keep the big one as im kinda fond of him and bought him for only $10. I might have to give in and get a tank just for the big pleco. My only concern with having the 4 oscars is when/ if they spawn how will they react to the other oscars in the tank? and is this doable? Thanks!
