I also now have two fish, although I think Mrs. fantail goldfish is going to have to go back to the aquarium shop because Mr. Beta is picking on her
The beta (he's deep purple and red so he's a bit harder to see) is named Bubble Boy and the red cap fantail goldfish has yet to be named
I heard that Beta's should live alone, not even with other Beta's because they are an extremely territorial fish. My cousin, Rusty, has like a 10 gallon tank for just two Beta's. They like their space.
