I will try to be short,
Know those dreams you only noticed they aren't real when you wake up?
Well, I was having one of those, I was cleaning my tank and I had a female betta on a tiny bowl next to it, then before I knew she somehow got into my male's tank and they started fighting, I removed her and when I see, she lost her whole caudal and pectoral fins, I was like WHAT ON EARTH JUST HAPPENED! Then I woke up... I think I'm getting over my head dealing with my aquarium... I mean I don't even have another betta, I plan in getting a female but in like a month time. O.o'
