I was wondering if I could add more fish. Preferably medium sized ones that won't get eaten. They don't have to be cichlids. Suggestions? Or should I add more severums/acara? Or just leave my tank as it is?
you have room for more fish - but i would avoid barbs
your acara colony would benefit from more members though - i'd take it up to six without blinking - you may get a more natural behaviour pattern from them too
personally i'm a pl*co fan anyway - what type do you have in there ? - you could fit another in along with the extra acara with little worries about turf wars in a tank that size
