I looked in my tank today and I seem to be missing a clownfish. I've looked in the tank at every angle, can't even find a corpse. He was just fine yesterday.
I am sure he wasn't sick, and I've had him for over a year. The suspects are:
1. longnose hawkfish (he seemed to ignore the clown)
2. mushroom coral (they don't sting fish, do they?)
3. lots of mini feather-dusters
4. turbo snail
5. 4 green hermit crabs
6. a two-legged, non-aquatic thief
I have eggcrate over the tank, so he couldn't have jumped out. Could a hermit crab attack and kill a sleeping clown?
