Would a hermit eat zoos?

[MikeP]

I had a nice patch of 6 small green zoos that disapeared over the last couple days. I did notice the same hermit by them the last couple nights, there was one left last night before I went to bed but when I got up this morning it was gone and that hermit was a few inches away. Is it possible that he developed a taste for zoos or is it just a coincidence and I have to worry about finding something else in the tank.

Thanks for any help
