Berghia movement question

[A.VOID]

added some berghia nudibranches a week ago.

Much to my amazement ... These things mowed down aiptasia like nobody's business. Went through about 10 nice sized aiptasia in like a week. Almost cleaned up my one island.

How long does it take for the nudi's to migrate to another island. I read where they don't typically want to be on substrate, but I assume they will go prowling for prey.

I'd like to get some. Where did u buy them?

local groupbuy. I believe we got them from one of the online breeders.

Like I stated, I was a little skeptical ... but they are the real deal
