I have a pet (very small) red ear slider turtle in an aquarium, and recently (we just put 2 mystery snails in the tank) a weird oily / slimy film that has a rainbow effect in light has developed on the surface of the water. It is obviously affecting the turtle because he avoids it and freaks out if he swims into it. Any idea what the film is and/or its cause?
