Update: berghia are not as sensitive as some may think because despite my INSANE water chemistry problems lately, I was up late last night and was able to spot 10 berghia out and eating away! I am 100% a berghia supporter and would NEVER recommend any...
The berghia rrived wonderful. All three were fine and I was able to hand feed them one small aiptasia each during acclamation. I got to see first hand how they chow down on them. Wonderful stuff.
