is there a creature that eats GSP?

They are non-aggressive, and don't bother snails or crabs... but they are general coral nippers. My guy has been fine for months eating nothing but algae, but recently he started decimating my GSP, ate all of my Zoas, and possibly killed my frog spawn and favia. This guy has got to go!

 

wow, that's the type of thing I was hoping for.

these are the questions I'll be researching on these snails - if you happen to know answers, feel free to post them and save me the trouble

Do they reproduce (will they get out of control)?

Will they basically eat any/all softies? Coral list in sig.

how big are they (can I easily spot them to remove if becomes a pest)

Hmm, that's all I can think of for now.

google here i come ;D

 

One guy in our local club had a emerald crab that ate his gsp.

That unfortunately was a one off, like the purple tangs that eat brain corals and acans.

 

I think those sundial snails are the same pones that kill clams as well. Is that the case pagojo?
