Hi,

Excellent photo - how did you take it?

It's better to post replies as it usually encourages more people to join in the discussion. You have aeolid nudibranchs and they are specialized feeders on cnidarians like corals, zoanthids, etc. If you have adults then you probably also have egg ribbons. You'll need to do a combination of dips and hand removal to get rid of them. The eggs can be inconspicuous so you'll need to carefully examine the montipora & plate when you have them out for dips. There are lots of posts here on RC reporting the results people have had with different solutions - check them out for details.

It looks like the Berhgia nudibranchs I keep to control aiptasia.
