Hello. I have a few cichlids that have some black/gray spots on them. It's mostly under and around their mouth, but a few have them in other places. I saw on another site it could be from digging. The spots appear to be smooth and almost like a natural part of their coloration. I don't see any scabs, flaking, irritation, abrasions, ect. They are acting/eating normally and it doesn't appear to be be getting better or worse over the last 2 weeks. Any ideas of what it could be and possible treatments would be greatly appreciated. I just don't want this to be something that gets worse later. Thanks in advance for the comments and I wish I had better pics. These guys move around non-stop. John
