Clownfish with spot

[Sammeyrama]

Hey I'm new to saltwater and I have two clownfish with a potential issue. I've had them for a little over a month. I quarantined them for 4 weeks then introduced them to a live rock tank that is 8.5 gallons with two hermits, a snail, and a tiny rose bubble tip.
A day later an one had a small white spot on his tail. Showed it to my LFS and they said it was probably stress. I kept an eye on the water parameters and they have been perfect and not fluctuating. Temp is 80. The spot went away two days later and now, a week later, they both have spots, one on his top lip and the other on his side. LFS said keep an eye on them and that it could be that the RBTA is stinging them. Not sure I trust them though. Any help would be appreciated guys!

Have they been treated with copper at the LFS or while you had them in QT?
Looks like Lymphocystis.

No copper treatments as of yet. I have some Tropical Science Marinemax that I started using today though.

I would avoid copper at all costs - there are better and more effective treatment options that are much gentler on the fish.

I've heard that about copper. Thanks for the advice!
