This may seem like a dumb question bash me if yah want but just curious to what monster fish I could keep in a 55 gal until a year time from now that wont out grow it in that time planning on getting some big but nothing big enough to out grow a 150 gal just planning on keeping whatever I get in the 55 for now until I move and set up my 150gal which is currently sitting in storage cause it's to big for one person to carry up 3 flights of stairs lol any ideas on predatory fish would be helpful
