i think you should get a fish you can keep for life rather shoving it off when it cant turn around... a p bass will outgrow ur tank in no time. do a mini predator tank. what about a giant bumblebee catfish, and a rare pleco then a centre piece like a male green terror or a rainbow wolf... like an amazon biotope... im fed up with filling my tank with big fish crammed in, im currently trying re arrange my tank around my midas pair, would like just those breeding with lots of midas juvies growing out i think... aint all about the big rare fish to show off here is it. alot of these tanks are boring, just two silver tigerfish in a 75 is nothing on a thriving community of 4-5 inch fish all interacting. or a breeding pair with baby growouts. thats my take on it, a lone flowerhorn or midas is another option... elongatus would be cool if you can find a confident one, a timid one will be boring. i had a manny which was active and cool, glass biting ect, got bord... i will say what i always do, an oscar is hard to beat, predatory, characterful, greedy, moody and colourful, can hand feed em... what more do you need!
