The last time he ate (big pink anenome about 20CM across) was 8 days ago and
only about 1 quarter of a giant prawn. His colour is still good he just has
gone off the prawns. Should I give him some hake instead. Or should I try
and get some new prawns or go for the smaller ones - the old ones I keep
frozen in the fridge until I thaw them for feeding?

Try different foods - verify what is the species of your anemone and try
to feed it what it likes... I found my bubble tip anemone prefers krill
over big shrimps/prawns. BTW - 8 days is not that long for an anemone...
Maybe it is not so hungry.
