I'm new to saltwater, and I noticed my young clownfish had white stringy poop and ravenous appetite a couple weeks after I got it. So I treated for internal parasites with API General Cure food soak and it seemed to have worked because there was no more white stringy poop. However, it's been a month since and it still hasn't gained back the weight and still looks skinny. I feed either pellets or mysis once or twice a day. What should I do? Repeat treatment? I've attached a picture.
