In the last week or so ,i see more and more of this round / half littel moons in my tank , it is growing on the rocks and on the back of the tank if some one know to tell what is it please let me know
Are you talking about the little white specs in the pic?
Quite normal in a new tank - the name of them currently escapes me, but they are harmless and will eventually vanish over time. Nothing to worry about!
