i am going to take a wild guess and say you haven't done a ton of research of proper setup and husbandry for your new terror : )
that can be remedied, lots of folks do it. check out the link below for our Nile Monitor FAQ at our site, and really think hard if a giant, mean, biting lizard is going to be the right choice for you.
carewise, check out our caresheet section, and read the Water Monitor caresheet, as well as the Water article i did for Reptiles Magazine (listed in the same section). i wouldn't approach a Nile monitor much differently from a Water monitor as far as husbandry goes.
check out our Monitor FAQ as well, there is lots of different info there.
get rid of the fish, and feed a proven, nutritious diet, feeder insects and rodents, period.
check out our available books, and #1 get the Savannah Monitor book by Bennett, it has the most up to date monitor husbandry info available in print, and you can absolutely learn from it and apply it to your monitor (or any monitor). #2 get the Nile monitor book by Rob Faust (also at our site), it covers a lot of Nile specific knowledge very well, and both books are affordable for every monitor keeper, and every monitor keeper should have both in their library : )
best of luck!
