I was going to visit some family and I was going to be gone for three days. So, as usual I asked my cousin to watch my fish. I told him that my fish would be fine if they went three days with out food, and I showed him how to feed my fry microworms.
When I came back I found the bottom of Inky's and Prince's tank almost covered in pellets. The water in my fry tank was cloudy (I think he put the culture medium in instead of just the microworms). And all of my other fish looked really bloated.
Have you had a similar experience?
