Poor rutilans juveniles are covered in velvet. Some have rubbed their scales off trying to scratch.
Then I look up and their bloody dad in a separate tank was rubbing himself on a leaf. Even with my torch I couldn't see any signs of parasites, although his gills were redder than normal. Might just hit that tank with salt and high temperature for a week or so as I am hesitant to use strong medication on everyone.
This velvet will be the death of me. Just when I think it has gone it rears its ugly head up again.
