fins

I have another clownfish and a goby and they’re fine. My clownfish is still eating and swimming normally, which i guess is a good sign How do i treat him asap? Attached a video below

Help! We have one anthia who has been in a QT tank since we got her, she’s due to go into the display tank tomorrow. Last night these areas on her fins showed up. At first I thought maybe ich, but the more I look at her the more I think it may be something else. It’s on both pectoral fins...

I just got a halichoeres leucoxanthus wrasse in the mail today and it has a blemish/ chunk missing on its top fin. It's a juvenile, just wondering if that should heal up and return to normal under proper conditions or if it just stays that way even through the adult transition.
