It's not stuck forever, it's more the camera goes inside the rock and all you can see is the inside of the rock until the fish moves enough for the camera to get out of there. I also caught one fish glitching through a rock.
Poor fishes starved when I switched windows to leave my comment yesterday. Woops. >_<
Setting up the plants and such shounds interesting. Maybe there could be some story about how the fish, newly unfrozen, can't digest actual plant matter from the get-go? To explain why the pond's plants aren't eaten right away.
