hey guys, after much talk with everyone, i need some help re-setting up my tank, and which fishes i will be removing. i currently have an Australian Aro, a Pike Chichlid, a Maganese, a Wolf fish, and lastly a FL gar. None of them seem to be fighting, but so far everyone told me its a ticking time bomb waiting to happen. the Aro is definently staying, which other ones should i keep??
