Black spot

[Hassan 2021]

Hi guys can anyone help me with this, while inspecting my fishes this morning I noticed this black mark on my fish. I have checked my water parameters all is fine. My tank is 180 litres and pretty unstocked. The fish in question is swimming actively and feeding normally.

Cant really tell from the picture but it could be genetics

Welcome to the forum!

Unless the fish begins to appear ill or act unusually, I don't think it will be an issue. I woke up one morning to find that my bumblebee platy had a black spot on her tail, and she is just fine.
