Emergency!

[jdurbin]

I've got white nudibranchs eating my montipora. How do I get rid of them?

You can start by dipping in coral rx. This will only kill the live ones it will not kill the eggs. So the best thing to do is to quarantine and start dipping regularly until you can break the cycle.

Six line and yellow wrasses are good too.
