Nudibranchs there still?

[KenRexford]

Added breghias a few weeks ago. They seemed fine entering but disappeared. I know that is expected. I also know to not use Aiptasia X while waiting. Now, I fear that I am letting the menaces grow with impugnity while waiting for the bergs to catch up but might have no actual bergs in there (died, eaten, etc.).

Give them time, typically you will never see them again after introduction.. it will seem like they are doing nothing then one day you will start to see the aiptasia disappear. Like everything else in this hobby patients is the key

Yeah, for me it was two months before I started to see the Aptasia disappearing. They go for the ones that are deep in the crevices first and then venture out once those are all gone. I'd say after 3 months if you see no changes then the Nudibranch might have succumbed to predation.
