Adding the nudibranches and or peppermint shrimp into a tank with established wrasses ain't going to work. I'll give them 5% chance of surviving.
I have a couple of peppermints in the sump. If I notice any smaller rocks/frags with aptasia, in the sump they go for 2-3 days. Aptasia gone. I do have some aptasia on some of the larger rocks in the display. Still trying to figure out how to get rid of them.
