Don't silversides have bones in them?

I tried an experiment awhile back where I fed the anemone heavily for about two weeks and then suddenly stopped.

My reasoning was that it would get used to the extra food and once the food became scarce it would split into an organism that didn't require as much food.

It worked! Or something did anyway. The nem split and I had two. But I tried it again later with no success.

The BLUF is that my nem never suffered from suddenly not receiving food.
