Broke Reefer!
I've noticed my mimic tang flicking across rocks and the substrate the last few days. First time I've seen any of my fish try to scratch themselves on the rocks (though I occasionally see my blenny use her tail to scratch her body). I've looked very closely at my tang and do not see any sort of white spots on her fins or body that would suggest an ich outbreak - in fact I've never seen white spots on any of my fish even though I am sure there is ich in my tank. My tang also has not really filled out much weight-wise - she was pretty skinny when she arrived and I can always see her very full tummy after she eats, but it doesn't look like she's really put any meat on her bones. Now with this flicking behavior, and the crash of my tiny tank, I'm starting to get concerned about her. Is there anything that could be going on other than ich since I don't see any white spots? I've been feeding every other day and nori sheets about 3x per week - should I up feeding at all? There is little aggression in my tank and water quality is adequate, though I recently changed foods and have noticed a diatom outbreak so might have some phosphates in my system from the new food (its a food my LFS makes that has similar ingredients to Rods and they gave me a free bag to try - I'm not really sure I like it though because I think the pieces are too small for most of my fish to really feast on once its thawed). Anyhow, any ideas as to what to do at this point? (And no need to link me to the stickies about ich and treatment - I know them!)
