Do remember where you got your Yellow-Lined Cleaner Goby? I've only seen them once and I'm pretty sure it was at Ocean Floor.Pretty sure that was how I lost my Yellow-Lined Cleaner Goby - Foxface got startled and Yellow-Lined looked really rough.
Sorry about the Aiptasia. That's the way my 125 went. I still see Nudibranches in there on several occasions but they don't seem to be making a huge dent.
That's pretty discouraging about the nudis. I'll probably try again though.
