I am looking for marine or FW fish, Marine fish must be able to live in a 75 Gal tank with some live rock, the FW fish must be able to live in freshwater only sorry no BW's for now, the FW fish must be able to live in a 55Gal for more then a year while I build my tank, I cannot take Gold fish and I would consider Koi when I have my pond set back up, Thanks
