From personal experience, and not sure if it is just my firefish personality or not. But my firefish loves to hide alot. Only time I really see him is after the light has been on for 5 mins or more. I know they are skittish fish by nature and need to have places to hide within your tank. Just not sure if it is normal for a firefish to hide all the time like mine or not. Just a lil FYI on the possibility of not seeing your fish much if you get one. Other than that, I think he is a wonderful addition.
