So I have a 6 footlong by 22 in high by 20 or so deep 125 gallon fish tank and was wondering could I put a silver Arowana in the tank for say atleast 2 years or so or how long would it last in the tank. Also if that doesn't work I am in search of some cool odd ball fish to put in the tank No bichirs but does anyone out there have soom good ideas on what to get in the tank I am an experienced aquarist just need some help deciding things is all.
