I just had a good friend call me about a fish that he had dropped off at another taxidermist 3 years ago. The fish has not been completed yet and he was wondering if it still could be mounted. I told him he could try to pick up the fish and bring it to me. I do not fill it will be in any kind of shape to mount. I believe a replica will be the best option. Has anyone messed with fish that have been frozen for over a year? If so how long is too long.
