If you say I have high nitrite or ammonia and these will kill my fish
within a day then why have they been sat at the bottom but very much
alive for over a week

The water was completely fresh 3 weeks ago when I moved into my new house


3 weeks ago?! It definately needs changing. Your fish are at teh
bottom because they can't breathe. Get an ammonia and nitrite testing
kit, and start doing water changes at least once a day until your tank
gets better.
