Leopard Puffer bubble tip sting?

[sirpuffington]

I’ve had my puffer full marine for about two years. Recently added a bubble tip to my reef tank a few weeks ago. All other fish in tank seem fine with no marks but these are on my puffer. Any thoughts?

A photo under white light would help really seethe burn marks, but if he was stung he’d probably have to run into the anemone, then the tentacles grabbed and stung him. Fish tend to stay away from them, unless they are clowns, they know what they are and will only run into it accidentally. So if that happened he probably learned his lesson and will be fine.
