I am a new fish owner who just got my first betta last week. At first, he seemed perfectly healthy. He was very active, bright red, and had a huge appetite. But two days ago, he became very lethargic, his color turned dull and grayish, and his fins are always clamped down against his back. He doesn't eat very much anymore, and he hangs around the top of his tank all day in a corner. I'm thinking this happened because the tempature in the room he was in fluctuates often, sometimes reaching 64 at night (it gets VERY cold in the winter where I live). The tank had a heater, so I thought it would be ok - I won't be making that mistake again! We moved him to a different room this morning that will hopefully stay warmer. Is there anything else I can do to help him recover? Do you think that it is possible for him to recover? He looks absolutely terrible - I feel so bad for him.
