ok so i got the divider in ( as per my other thread ) so the cons have an area of a foot long by 18 wide, which should be big enough for them and there family that there raising and i have my magnum 350 going on there side ( and to cut out my old fish net to put over the intake and rubberband it to the intake ) so now the oscars have a 4 foot by 18 room ( well which is 90 gallons for them cause its 25 inches high ) so do you think this will work in the long run? i only have 2 oscars and 4 black skirts and a few diff livebarers on the oscars side. and the pair of cons and there frys on the other side. the oscars are more active then ever since the cons dont bother them anymore! oscars are 6 and 6 1/2 inches.well comment away!
You really need to trim your stock down to non-breeding fish so that you only have those fish without the extra hassle of dividers, fry or extra tanks to worry about. It is all about priorities.
