I have a well established 55 gal. fish only tank that is also home to 2 blue crabs, a sand sifter and a large Volitan (lion fish). I have owned the starfish for a week or so and don't really know what the normal behavior is. I was wondering if the starfish should stay at the top of the tank with the arms at the top of the water. The tip of the arms are also curled slightly. Is this normal? Tests on water are normal with the exception of the nitrate being a little high(45ppm).
