I just noticed this on my molly - it looks like a white/nude zit spot, similar to the kind we get on our body. She just had fry on Saturday, and since then she was harassed by the two male mollys. I don't recall seeing this on her before and I've had her since mid-Nov. Also, I don't believe it's ich since it's not a white flat spot, more like a pimple bump. She is not flashing and her behavior is normal. I noticed that the black freckle spots have increased these past few weeks and I have read online that aging mollys get those.
