I have a female Anthias and as her fins have gotten longer I’ve noticed a spot that I can’t tell if it’s a parasite or not. I’ve been watching it for several weeks. She’s thriving and coloring up potentially transitioning to male. I’m hesitant to medicate if this is nothing, but also don’t want to introduce anything unnecessarily to the display. She’s been in observational QT since June 26. She was in lfs for a couple of weeks before that. 2 Clowns in tank seem perfectly healthy except battle scars where they are incessantly nipping at each other. I’ve attached the best pic of her tail that I can get. Was thinking of medicating for a week prior to introducing into display, but also would love for it to be nothing and just proceed with introduction. Help/suggestions appreciated!
