Invertebrate Care sticky thread?

[ThunderGoose]

I would love, love, love to see a thread on how to care for invertebrates and what to expect from them as a sticky in the invertebrate forum.

For example: Fan worms (feather dusters) should be fed x, y times a week, if they lose their crown it could mean a or b, if they come out it could be because c or do and what should you do if that happens.

Thanks!
