How do you guys try to get any stuck fish out of any decorations? I’m afraid of pushing it too hard from the back (or should I push it from the front back) to help it get unstuck?
In that photo I would probably lift the decoration and push the fish out from the front to back. If you still are unable to, try to get a hammer or something hard to break the decoration without damaging the fish directly.
I mostly recommend that unless the fish is exactly half way through (then pushing from the back makes better sense overall).
