I got this melanurus wrasse last week. When I first got it, it was gulping air at the surface. Now it seems to be swimming around the tank without too much distress, it doesn't seem skinny and has good coloration. I tried feeding and spot feeding thawed mysis and brine shrimp with selcon but it wasn't even remotely interested. I have some fairy shrimp eggs laying around which I'll hatch to feed it. I did a freshwater dip a few days back but nothing came off. What is the best thing for me to do?
