Thanks everyone for you're responses. Especially to danmhippo, thanks for sharing your experience with the berghia. I'm going tostart with the control using peppermint shrimp and then using the syringe with kalk as a secondary plan. Happy Reefing everyone!
I have a pretty nasty outbreak of aptasia in my 55. I'd prefer to use the natural method of eliminating them. Besides peppermint shrimp I want to also try using berghia verruciornis nudibranch to eliminate and control these pests. Anyone know where I can get the berghia verrucornis nudibranch...
