okay,I know this sound pretty sick but I was thinking it would be pretty kool to somehow preserve like giant fish heads so I can use them in a fish tank as ornaments.I was thinking of using skeletons of fish that eventually die in the future,but,that doesnt happen often.So I got an idea-being that I am also a fisherman-if I caught a huge bluefish or striper in the ocean,I can take the head and let nature do its thing outside, which should take like a week at most.Then once its just a giant skull I will attempt to paint it with silicone or maybe something else I can find that wont harm my alive fish.once its dry,it will become a cave for my live fish.kinda like all the fake alligator heads and steer heads etc ya get at the pet shop.any ideas?What do ya's think?
