This may be a daft question but I think that my Scorpus Tang has got white spot. But the thing is i,m fairly new to keeping marine fish but what I know of white spot is that they itch on rocks and sand etc. Well the thing is my tang isn't doing any of that it's still eating very well almost anything that I put into my tank it eats ie mysis, Bryneshrimp, Red Plankton + Sea Veggies also I have not seen him scratch even once. What I want to know is that doe's a fish with White Spot automatically scratch...?. My LFS says they don't have to it's not always the case but which ever site about white spot I look at they always says the most common sign is itching or scraping on sand and rocks Thankyou in advance. By the way at the moment not treating it apart from my UV sterilizer is in place was wondering what to do if it turns out it has white spot.
