Have a carpenters wrasse that has been going downhill since yesterday. Received on Tuesday with a group of wrasses. Blue flasher, pink margin and whip fin. The carpenter was the most active of all of them no problems eating or coming out. Did Prazi on Thursday for 24 hours then 25% water change and carbon. One I added the carbon the dish started hiding but would come out to eat. Last night was the first time it didn’t come out to eat and breathing was fairly rapid. This morning breathing is slow but labored. I started dosing copper power yesterday. Have not tested yet but with how much I’ve added I should be around 0.6ppm. The fish has flipped itself upright since the video and is currently laying on its belly.
