Okay, my salinity is 1.025, Nitrates are 5-6 and my ammonia and nitrite are zero. Everything else in my tank is doing excellent and I got this new hammer a while ago. He’s been in here for about a month and the Urchin and hermits were kinda rolling on top of him and irritating him. I moved him today and he seems to be doing a lot better. He does have some whitish stripes though, do I need to be worried? I have yet to see him expell any zooxanthele.
