I had bought my 2 red eared slider turtles 3 months ago. They have a great appetite, bask often, are very active and don’t appear sick. My tank has a basking dock, UVB lighting, filter, regular water changes but no heat lamp.
However, for the 3 months, both turtles were slowly developing weird shiny spots on their shells that started from a small area and had spread all over their shells now. These shiny white spots can only be seen when they are underwater and with a strong light.

This is what it looks like when the turtle is dried.

I read online that it could either be fungal infection or shedding of their scutes. Can anyone tell me which is it?
Thanks!
