Saltwater Aquarium/Hippo Tang


I just got a Blue Hippo for my tank.. Now I knew he was a young Hippo and they said he would hide for a while.. But now I am getting worried becouse he has been hiding for over a week now and he is behind and have stuffed himself in the rock work I can just bearly see his tail..I don't think he has eaten and I am wondering should I be worried about him or will he hide a while longer still. Will he ever come out to eat or should I try to move the rocks to help him.. I would hate for anything to happen to him..    Thanks Valerie

Good morning Valerie:

Sorry to hear of your troubles. I would recommend to try and gently coax him out from behind the rocks to check on him. Make sure his sides are not sunken in; if they are, this is a sign that he's not eating. Try many different types of foods, until you stumble upon something that he likes.

I wish you luck with all your future saltwater aquarium endeavors.

I possess over twenty-five years of hands-on experience and knowledge in the ecology of aquariums. Beyond the traditional, I have successfully tested and sustained environments that have been uncharted territories for hobbyists, for decades. I am the first to admit I don't know it all because there will always be something new, amazing, and exciting to learn about, as discoveries are made. It's a hobby one can never outgrow, or grow tired of.

After High School, my experience and love of marine animals influenced me to take up studies in Marine Biology. Throughout college, I studied Microbiology with an emphasis on Marine Life, as well as numerous other sciences. I continued to advance in this hobby, by building a dozen or more saltwater ecosystems all utilizing Microbes as the major source of my filtration method.
