Good day,
I currently have a yellow wrasse and a red coris wrasse in my quarantine tank. They've been in there for 20 days.
I have never noticed any signs of disease or illness with these wrasses but I still them with cupramine. After about a week, the young yellow wrasse developed some redness around its gills and I was certain that it was from the copper. When I removed the copper, the fish went back to normal. Right now both fish are eating well and look healthy, except the red coris wrasse yawns every minute or so. There's no ammonia in the water or any copper anymore. Why is it doing that?
