hi guys, my 6month old female clown has this weird patch on her that i noticed yesterday. shes acting and eating normally, no new tank mates for at least 3 months and water params are good. shes in a 15g nano with her bonded male clown some cuc and mixed corals. i cant seem to figure out what that patch is??? its on one side in between her belly and tail. no patches on the male so far. here’s a youtube link to a video of her:
