I have a yellow tang that I've had for several months. The corals in my tank have been there long before him. I feed him flakes in the morning and various frozen food at night with a seaweed select strip haning in the tank. I caught the little guy nipping at some xenia and my lobophilia (sp?). This tang is posibbly the fattest I have ever seen a captive tang and I (for awhile) thought I was over feeding it. Has anyone else seen a yellow tang do this and is there a way to make it stop?
