Clownfish skin issues/scratches

croff11 · Mar 31, 2020

I have been dealing with my tank overall being “off“ for the last week and have now noticed the marks pictured below on my clownfish. Overall multiple corals in the tank have been upset but that is for another post, battling cyano. I first noticed the marks yesterday and will continue to monitor them and post updates. I have also noticed reduced action towards feeding today, I have not notice any rubbing on rocks or sand bed. I recently converted over from a Aquaclear70 as the filtration on my 29gallon to a CPR Aquafuge2, I took all the media and moved it into the aquafuge and added clean chaeto from algaebarn. That is the only major change that has occurred to the tank in the the last month.

Photos lights changed to see better.
