I have had one Goldfish for about 8 months and he has always been fine. This morning when I got up and turned his light on he was lying on the bottom of the tank but began to move around normally and ate. About an hour later I notied he was doing the same thing but when i got close to the tank he would move around and look at me (he is very social). But he continues to lie at the bottom of the tank when left alone. What can I do and what is causing this?
