I had fresh water tanks for many years and three months ago started my first 90 gal marine tank . I had some good advice and guidance on the startup, cycles, live rock, filters, protein skimmer etc. The water quality was excellent so three weeks ago I added 4 green chrome damsels. Last week I added a yellow tang and a maroon clown. For the week, everybody seemed fine. Actually they all still seem to be fine but the maroon clown has developed a strange behavior. For the first couple of days he/she swam freely around the tank and favored a particular notch in the rocks. For the past three days, he spends a good part of the day hiding behind the protein skimmer. I was wondering: is this is an unusual behavior or a sign of something being wrong?
