Killer Hitchhickers

[pelena]

I was just wondering if there is a bad hitchhicker and critter list anywhere out there. I only know about aptasia.
Pics of your naughty hitchhickers would be cool too.
Thanks

I'm not sure there is a list - but they come up now and then and you can search. Maybe people will add
Bad hitch hikers include:
mantis shrimp
tube hydroids
asssorted rock crabs
various types of flatworms and nudibranchs
some relatively uncommon extremely large bristleworms
Anemone Majano (little green anemone)
cirolanid isopods
sundail snails (predators on zoanthids)
Pyramidellid (sp?) snails (predators on giant clams)
