Black spotting on laps

[Rotaryp04s]

My laps started to develop black spot on their face and body. Should I be worry?
I will post pics soon. My laps are nice green color but the black spots look strange to me. Any idea what this could be.

My old laps had some black spotting and my cogicus has a black spot on her tail, nothing to be alarmed over

It's mostly common in wild-caught lower-jaw bichirs from my observations. It'll fade away
