Spot on scopas tang

[dbleoh7]

Just today I noticed this spot on my scopas tang. I've had him for about 6 months and he has been healthy the entire time. I haven't added any new coral, fish, CUC or anything in months... I did notice about a week ago I got these things on the glass in the second pic which I'm not sure what they are either. ID on both of them? Are they related?

Looks like nick or injury that is healing. Just keep an eye on it to assure it is Not progressing into an infection such as bacterial
Second pic is an acoel (ghost) flatworm and although not harmful can be an issue in numbers as they will smother a coral blocking light needed for production of coral building block known as zooxanthellae. Remove manually. If there are several, consider adding a wrasse that will eat them such as: Yellow coris-6 line-lunare or melanurus. Springieri damsel will eat them also.

Thank you! I'll keep an eye on him. As for the flatworm, I've had flatworms before but they always had a red hue to them and these don't. I guess it's a different type? My six line wrasse took care of those previous ones but he seems indifferent to these ones...
