I have a beautiful orange Saffron Molly. He had a very vibrant coloring that included a very black tail. He looked like someone to the front and back of two Mollies and combined them, color wise. He's always had my 2 guppies heart. They follow him everywhere. I've had the three for about a week. Yesterday, he wouldn't leave the bottom of my tank. He just rested on the gravel. The guppies wouldn't have anything to do with him. He's isolated in the only extra tank I have, a 1 gallon tank. Today he started swimming in circles. He is also tilted when he swims. But still, more than anything, he just sits there. Now though, he is on a 45 degree angle.
Two days ago, we got our first cold weather in Texas. The tank got to 72 degrees overnight. So we turned the heater up. Then the tank got to 80(that evening). so we turned it down alittle. Again, the tank got to about 74 last night. so we have the heater up again. I'm keeping a closer look at the temperature today. All my other fish seem to be doing well.
I'm keeping the tank at 78 degrees,. I have a 37 gallon that's been set up for about a month. I've only had 1 fish die very early on before this fish was ever introduced.
I need to know what it sounds like it wrong with my fish. How is it treated? Can it be treated or should we let nature take control? What caused this? Should I be worried about my other fish? What can I do to prevent it from reoccurring?
