This is what my Long Tenteacle Anemone did.
It was Perfectly healthy last night and when I pried it away from the anemone the other side was partially digested, i.o.w. it had been eating my flame angel for some time.
There was no time for it to go from healthy to sick to being eaten that much, not in 12 hours.
It was never going to get my angel into it's mouth, but that wasn't stopping it from trying. Evil, evil anemone....
