I had one hide in my tank for a month and a half. I thought for sure he had either jumped out or starved to death and got eaten by something in the tank. Turned out that he was scared and hidding from the trigger we put in the tank. As soon as we sold the trigger (a month and a half after getting him) the firefish came out of hidding. Unfortunatly our firefish took to carpet surfing during a tank move later on.
