I would get a nice house and make a nice big in ground indoor pond in my living room and stock it with aros and possibly a RTC. Then i would have one tank in every room of atleast 200g and fill them with discus, flowerhors, gars, and then in the master bedroom have a huge 500g tank filled with my red belly piranhas, then i would turn the basement into the saltwater fish room, i would have a tank big enough to keep a black tip reef shark for life. Also in the living room would be a 300g saltwater tank with a huge snowflake eel and a nice big lionfish or 2.
