I thought I'd throw this out for ideas...
"Something" is eating a Euphyllia here, a Euphyllia there. It ate over half the heads of a hammer, consumed all three heads of an Octospawn. This week it has eaten over 90% of a beautiful green Alveopora whose skeleton is the size of a tennis ball.
The rampage happens at night. My husband stays up past when the tank lights go out and says the fish are asleep so he doesn't think it is a fish. Since we've been noticing the damage, he has been specifically watching the Alveopora and never sees any suspects, day or night, so we assume a critter is coming out in total darkness after he goes to bed.
Our 300g tank is 5 years old so there may be a peppermint shrimp lurking somewhere but we never see it if it is there. Years ago we had a tiger tail sea cucumber but have not seen it in probably 4 years. There is a tiger shrimp that we see maybe once a month. Those are the only "hidden" critters we can think of that might still be in the tank.
Based on how quickly the Alveopora has been eaten we think it has to be a critter of some size. Anyone have ideas or similar experiences?
