Thanks Awi! Not sure if it was the intro of the wrasse that stressed him, as he developed ich shortly after, but he was eating extremely well and recovered (or visually at least) in a couple of days. So maybe that took it's toll.
Tank is done, still no power and the last fish was plucked out two days ago. Poetically the last one to go was the first fish I bought.
My starry eyed hermit was the last survivor, but I am not even sure that he is still in there, I can not bear to look at the tank anymore. And I will just wait for the power to come back before I do.
Thanks guys, I am sure that there were some monster tanks lost, so I am at least thankful that I was not deeper in to the hobby. I will rebuild though, probably very slowly until I can get some Lipa-proofing in place.
