I just got my first Blue Mandarin Goby to go into my 29 gallon tank. After 3 hours in the tank I had my Goby eating frozen shrimp. From what everyone at the aquarium stores and webpages online the Goby should be hiding and not eating for the first couple days. Sould I be keeping a close record on the conditions of the tank and documenting them or is this behavior more common then I think.
