0006116: Fish in aquariums interfere with vermin behavior checks
Part of the game's "process vermin" logic includes updating all existing "vermin" items in the fortress for milking, escaping from animal traps, air-drowning fish, etc. There appears to be a bug in this logic, however - once it encounters a vermin fish safely stored inside an aquarium filled with water, it breaks out of the loop and skips processing for all remaining vermin in the fortress (i.e. "break;" instead of "continue;").

This bug appears to date back to at least (which is where I first found it).
