The past month I have noticed that when doing a wc and vacuuming the sand bed my 2 clowns are charging after my hand. Doesn't hurt much. It's not like getting burred by a car fish. Which had happened to me. But they just started doing this within the past month. I'm not seeing any eggs. I did see the female go after my angel fish today also.. is this normal behavior or are there eggs I'm not seeing around my frog spawn that it hosts?
