Cal B Posted August 26 Share Posted August 26 Hi all, I noticed one of the cardinal tetras I’ve had for several months has developed what appears to be ulcers which protrude from its body. You can see the rather large ulcer on one side and now more seem to be developing on the other. The ulcers appear a flesh colour not white. Does anyone know what this may be and how to treat/should I euthanise? Thanks and sorry if photos aren’t clear. Link to comment Share on other sites More sharing options...
