It is best to go on and leave. I think the fish will loose some coloration the longer it is in the livewell. Also when you get it home if your not going straight to the taxidermist, wet a towel, lay this fish flat on the towel and wrap it tightly making sure the fins are laid out flat. Put the towel in a trash bag, wrap the bag tight around the towel, tape it up and put it in the freezer until you can take it to the taxidermist.

Hope this Helps
