I am currently in the process of starting my first saltwater aquarium which is a 120 gallon FOWLR. Yesterday I got my first fish, a banggai cardinalfish. It is currently in my 10 gallon QT tank before it will go in the display. Since I got it yesterday, it has been hiding in the corner of the tank underneath the heater and has not eaten anything. I have attempted feeding pellets and frozen mysis shrimp. At the fish store it was out in the open and eating (I asked the employee to feed it so I could make sure it ate). I know it is normal for fish to be nervous the first few days in a new tank, but I just wanted to ask in this forum and make sure this is normal and that there’s not anything to be concerned about. Does anyone have experience with banggai cardinalfish doing this?
