White spots

[gadazobe]

Been sitting watching my featherfins at play and noticed that all three of them have a few white marks on them. It doesn't look like fungus, the marks are not raised at all. One of the fish has them along both sides - perfectly symetrical. It looks more like lack of pigmentation. The fish seem fine, eating like vacuum cleaners and doing whatever featherfins do. Has anyone else come across this?

When I had mine he tended to get chalk-like marks on him from minor scrapes.... never did any harm and disappeared easily

saw mine this morning he or she has a chalk line mark again, nothing to worry about.....
