About two weeks ago I decided to buy a Betta to go in my community tank. Knowing the males have a penchant for wanton violence, I bought a nice, short finned little female one. Gorgeous pink and silver colour. I named her Betty.
Sunday night, one of my guppies was looking a bit peaky, constantly swimming at the surface. By Monday he was a goner, lying on the bottom with a fin missing. I put it down to illness/age and opportunistic bottom feeders.
Second guppy starts looking the same way that night. Tuesday morning, Betty's playing with it like a cat with a mouse, is revealed to be the murder criminal. Betty is moved to a new tank.
Cut to today. Third guppy goes belly up for reasons unclear, Betty follows shortly after.
