cheers for the advice guys.....to answer you atnixon i got 3 blue green chromis....2 pecular clowns....1 yellow tang....2 cleaner shrimps....1 peppermint shrimp....4 blue legged hermits....1 snail.(not sure what kind).and various soft corals. as for the yellow tang i went to my lfs and talked to the guy and he recomended a fresh water bath for it..he said he has used this method to some effect .... so i did it tonight ...i prepared the water to the same ph and temp as my tank and dipped him in....he didnt seem to mind too much and when i put him back in the spots were all gone.....hes never missed a beat since hes had this ich and even after this dip hes still full of life and eating heartily... i gave him garlic and spiritula just there and hes first there for the food...... hope this sorts him out..
