Dark spots

Hey everyone
I noticed some dark spots on one of my discus 2 days ago just wondering if anyone has seen anything like it before.
Thanks

Are the fish fighting? and/or you have plecos in the tank? To me those appears to be peck marks from other fish. It should clear up with a few good water changes.

Thanks pat
I have only seen a little bit of pecking while there being fed. I'll keep a bit more of an eye on them. I done a 50% wc today instead of a 20% I'll just keep that up for a week and see how that goes
Thanks again

No other tank mates except 3 gold mystery snails
