Hi there. I have what I believe is a female Bluethroat triggerfish. She seems to have developed two white spots on her top and bottom fin. Otherwise she is acting normal. I have attached a video. Any advice as to what this may be is appreciated.

Too large to be ich. Could be broken fin rays, or a mild viral disease known as lymphocystis:

So this is at least better than an ich outbreak right? My juvenile orange shoulder tang also appeared to have a similar looking dot on his fin this morning. I have attached a video for reference.
